yea i know heddmans are good but hookers are better heh heh =) *looks@mark*....but seriously...the other night when my girl and i were goin to new jersey my cat back broke....the 3 inch pipe broke right behind the cats and started drapping the ground at 70 mph...i immediatly started divein across 3 lanes to get off the freeway....but, yall know those little metal grate things that seperate the bridges for expansion and contraction in different temps...well guess what that 14 guage 3 inch tubin caught on...when it caught it hit so hard it locked my seat belt up and it actually lifted the back of the car about a foot of the ground...and scared the **** out of me....i finally got to the shoulder and inspected the damage....when i looked under the car i didnt see my exhaust at all....i looked to the back of the car were the muffler would be and i saw that the 3 inch i-pipe was damn near wrapped around the axle ....the over axle pipe was bent in half and the i-pipe was twisted and bent in half also...even both tailpipes were kinked very bad....it bent one of the little lips on the panhard bar and from what i could see nothing else was hurt *sigh*...i limped it 30 miles back home and cut it off the next day and when i did the axle dropped 3inches because it was bound up cuz of the tubing wrapped around it....yes i took plenty of pics...

i went to an exhaust shop and they was 300+ for a cat back and woulld have to take off the "n10" because it busted the flange behind the cats.. so i figured now would be a good time to do headers...i dont have very much money right now thats why im gonna get the heddmans...and im gonna do a dual exhaust that i beleive "fast3rdgen" did....i looked at tubing today ata parts store and it was 5.99 for 18 inches of 2 1/2 inch which is waht he used....i just need the "s extentions" and mufflers....so ill be able to get it done for around 225 which is 100 less then the shop wanted and 150 less for there dual exhaust...


my question is...what is the heddman part number for there long tubes that will fit a 91 gta with a t-5 and all acceseries he used the hookers with the s extentions...will there be a difference between the headers and will the "S" drop it below the cross member?
...thanks guys
sorry for the long winded post

Hedman long tubes won't fit with a T5 without a little "persuasion"

 

i'm sorry to hear about the exhaust dude!!!! i would have probably cried!!!!

but it's all for the best because the exhaust that you want is 10x better than what ya had........

i think fastthirdgen has given alot of people including me a good idea!! thanks fast!!!!

the part number for the headers is 68460 from jegs for 104$

be sure you get the h crossover from flowmaster and x extensions........

good luck!!!

 

Also if your car is lowered the mufflers are going to be really close to the ground. The headers collectors should be alright. You could stick an X-pipe right after the transmission too. The driver's side header will also need an O2 sensor bung welded in and switch to a heated O2.

In about a week or so I'll have an extra pair of 2.5" hooker aerochambers that I used for about a year. I'd sell 'em for REAL cheap.

 

does hedman make longtubes for a 91 305tbi w/ the o2 bung already welded in?

 

I was thinking about ordering these headers to...i heard the hedmans dont fit very well..how well would they fit with a 700r4...oh yeah and they will be installed while the engine is out

 

Should be fine on an auto. If the motor mounts are old and the motor sits lower one of the driver's side primaries might hit the k-member.

and I don't think they come with an O2 bung. costs something like $5 Canadian so that's like 1 cent for you guys.

 

Must modify rotary A/C bracket
Designed to fit and clear with 700R4 or TH-350 transmissions.


does the a/c bracket apply to me?...and what will i need to massage for them to fit with my t-5.....and im guessin that the flowmaster h crossover and extentions can be found there aswell? on jegs that is.....

how much does it take to weld in the o2 bung....and my car isnt lowerd...

 

badgta do u have the part number for the h crossover?

 

X-Treme ''X'' Junction Only
500-18820


is this what your talking baout?

 

Don't have AC so don't know about the bracket.

I had to flatten the driver's side collector a bit to clear the bellhousing where the slave cylinder mounts. It hurt to do that to brand new headers but they work great!

for the O2 bung, you could cut the hole yourself and go to an exhaust shop and have them weld it in. It would take them about a minute

 

how did u flatten it?...and was it hard to do?

 

also how much SOTP did you get? even better would be track time improvement

 

okie...to flatten. held it between my legs then smacked it with a hammer a few times until it fit. very precise!

as for SOTP...before exhaust I couldn't tell if I was flooring it or not. ran 15.4 @ 89MPH with burnt clutch, cheap gas, overheating, wrong shift points, etc...my first time at the track.

after exhaust...
scared the crap out of me the first time I almost fell out of the seat cause I wasn't holding on the wheel tight enough. People told me header + exhaust would get me ~20 HP so I wasn't ready for that.

g-tech showed 14.6s' @ 97 MPH and data logging shows around 14.6 @ 96MPH w/ 2.2 60 ft's

I can keep up with my friend's 87 vette w/ exhaust and other little mods, and also LT1 Camaro SS auto.

still need to go back to the track though for real timeslips.

 

jegs has everything i mentioned....

heres what everything costs...

headers part# 500-68460 104$
universal s # 500-18806 23$
40 series fls # 389-42541 120$
h crossover # 389-15920 40$
____
287$

you will also need about 8ft of 2.5" pipe to hook everything up......

 

hmm i might do it. I was gonna run single but this would be much much cheaper and better flowing. Do you have to run the H crossover? what would happen if you didnt?

 

cheezx..talk about BFFI (brute force and ****!n ignorance) lmao...ill do that when i get um...

badgta to me that looks like it would more restrictive then the 500-18820 the"x junction"....also the h-pipe looks a little to wide for what im doin...i want to have the same setup as fast3rdgen but put the x junction between um....i dont have to use it or the h-pipe but i would like the equlazation for increased power....

im sure i could come up with somethiun creative to use the x junction..


300 posts!!! yea!!.....im gonna catch you mark sheilds lmfao

 

all the h crossover will do is let exhaust go to each side to equalize pressure on both sides......

if you can afford it go with the x, but have somthing of a crossover......

 

How does the crossover increase HP? I just odered everything to complete my exhaust. I ordred everything to run duals like fast3rdgen did....should I order the crossover to???

 

the crossover will increase power becasue 2 cylinders on the same bank fire almost at the same time...so the puleses are fighting for space on that side of the exhaust...when u have a crossover the puleses can move back and forth through the crossover so the spent gasses evacuate with less resriction...u dont have to use one but it helps....

 

try to put the crossover the same length from the collectors as the collectors are from the exhaust valves. then they will increase power over the same RPM range as the headers. and an x-pipe is better.

maybe you guys should think about putting mufflers under the rear bumper instead of under the car. WAAAAAY more ground clearance that way. that's the way mine is as of today. no worries about speed bumps. even with 5 guys in the car

 

Well I ordered everything. When I got to the exhaust place ill ask them how much it would cost to run the mufflers under the bumper. You still have no ground clearance because of the long tube headers so it doesnt really matter.

 

im doing the same dual setup on my maro, im just buying 2 "t" junctions and welding them up w/ a crossover, hell of a lot cheaper than the ones in the magazines. a crossover makes it sound a little better, smoothes out ur exhaust

 

I just got my set of hedman long tubes in....i know why they are so much cheaper than hookers...because they are made cheap. They are decent looking headers but the flange just looks kinda cheap and half the paint was already off right out of the box...but hell they are only 109$ and paint is cheap.

 

You guys really need to search before sarting posts, I have the Heddman full tubes installed with true duals-SUCKS Save your pennies and get the Hookers otherwise for a daily driver you're gonna hit every bump in the road. With a full tank of gas and noe one in the car, there is 3" of ground clearance between floor and bottom of muffler-Flowmaster knock-offs called Super-Flos same exact dimensions as 40 or 50 series sepending what u want, sound, but at a cheaper price.

 

another

 

no wonder!!!!! the headers are fine clearence wise from your pics, but the exhaust under the floor pans are whats so low.......

look at fast3rdgens setup..........

to me a header is a header, if it clears, no spark plug interferance, and are made ok, then it's a good header.......... theyre going to waste over time and need replacing sooner than later if ya didn't get them coated, so why waste 500??? on slps??


heres a pic of mine painted with the high temp stuff...

Those headers look like they tuck in much better than the hookers. Your problem is the pipe right after the headers. To late now im gonna be running true duals with hedman headers since i already got them. Im thinking about buying another set of the long tubes sanding them down and coating them real good. Id do it to the ones i have no but i dont wanna have the car down any longer i miss it. hell looks like a real good headers for 100$...just needs some high temp paint and ****.

 

No, seriously, the problem with the Heddman full tubes is that they "tuck up" too well. The end and center of the collector is up where the pan bolts onto the tranny, tranny linkage is only like 3" behind the collector W/an auto that is-manuels are gonna naturally be different. The pipes coming out have to be bent on such a way that does'nt let you run the pipes like in a Hooker header system which collectors hang lower thus allowing you tto run the duals down the tranny tuneel and allow for some extra ground clearance. Look underneath your car while it's parked on flat ground, then try to imagine what ever size tubing your gonna be running having to bend under the front "frame" Not only that, but the A-arm had to be torched off to allow for cleance, engine had to be pulled up 3" when first installed by shop to get them in there, when I was having first tranny rebuilt I cut the ears for the dust cover off so I could slide them in from underneath. Then when I installed the TH350, I cut off both ears just so it'd be easier on me to get it into place. Changing plugs is'nt bad, getting at the header bolts is'nt bad, but I also removed the A/C box, otherwise it's gonna be a PITA to get at the pass. side bolts and/or plugs. Fuel boil is gonna be a major problem as well as under hood head-unless they're ceramic, as soon as I hit 180 degrees I know I'll have a "bog" when I mash it-street driving that is, cause my car has the fuel line coming up over the tranny and running up the pass. side right next to the headers. Starter is also gonna be an issue-the headers almost rest on top of it so heat soak will be of concern, plus if and when the starter goes out (I had to, but would anyway install a new one just because), tyou'll have to remove the header to get it out. Getting at the oil filter is also a chore cause the header/pan clearance leaves much to be desired-don't plan on putting oil in the filter at oil change cause you'll have to twist it every which way to get it in there and you'll wind up with a face full of oil. I've always used copper gaskets on the heads and switched to dead soft aluminum on the collectors-have'nt ever had a leak. I'll agree, they are cheap-when I budgeted my new drivetrain the hookers would'nt pass at that time, and if not for my sponsor I would've had a hell of an exhaust bill-but I dropped him after seeing the results, paid for material, but not labor-could'nt believe they had the car for a week and what I got is what they came up with. I mean it works, car runs the smae number corked or uncorked but **** is it ugly, and I scrape everything with a passenger in the car. Just some FYI for you guys who thought like me cheaper was better-it'll come out the same in the end believe me.

 

with a T5 you can actually run the pipes above the tranny x-member and go straight down the driveshaft tunnel. or you could make an x-member with the humps in it for the pipes. the lowest part will still be the mufflers if they are under the rear seat and will bottom out unless you hammer the floor in. but my car was lowered, it wouldn't be as bad with stock ride height. gotta be careful when people are riding in the back though.

 

i agree there could be a problem with the length it comes down, but still from looking at your pics the mufflers routed under the floorpans are whats the trouble......

theres no way the headers all the way to where it bolts to the collector will drag...... if it does the so does the bottom of your car......... you got probs.....

did ya ever think of routing it down beside the tranny tucking it anywhere?? thats what i'm going to try......

again, heres another pic of mine with the high temp paint.....

 

no, no, I wanted to route the exhaust in the tunnel-BUT YOU CAN"T WITH THESE HEADERS!! What you see with mine is basically what your gonna have to do. Once you get them into position, your gonna look and say "oh, that's what he meant" I wish I had a pic from directly under the car to show you what I mean. After the collectors there is'nt enough room between the "frame" and transmission to route pipe down the tunnel-it is impossible, unles you channel out your floor boards to accept the pipes. I'll let it, go cause like I said once you finally get them bolted up it's gonna hit ya in the face and your gonna ****, now I know why people run Hookers and have good looking exhaust and Heddmans suck-you'll find out soon enough

 

seeeeee..... he actually dosen't have the s extensions turned all the way down....

 

well damn...i already have them and im outta money so i guess im gonna install them anyways. We will have to see what happens. My car isnt lowered and it sits pretty high for a camaro after installing the KYB shocks/struts...we will have to see what happens.

 

F-crazy... where the pics of your twisted up cat back???

 

so to install these headers while the engine is on the car requires lifting the engine? how far?

This time im gonna do it while the engine is out but next time the motor will be in.

 

im pretty sure it needs to be lifted at least 3 inches

 

If your not real attached to the dust cover on your tranny, remove it and cut the ears off both sides of the tranny, this will help the process alot. Then just have the torch on hand to start cutting away A-arm mount otherwise it will not bolt up to the head, and if you dimple the header the required amount you'll pretty much shut off the drivers side collector all together-it's that bad, no the mention the engine torques to the pass. side so you'll have to allow extra room for that also unless your running solid engine mounts. Soak your manifold bolts before attempting to remove, the shop that did mine busted off a total of 6 exhaust manifold bolts off inside the head-they had to drill and heli-coil to make it right again. I've also read many horror stories on this site with the same occurance happening. If you have the A/C box on pass. firewall and the engine is in stock form, it'll have to raise a minimum of 3" to slide them in/out. Since your doing this with engine out, you'll have to probably put it and out a couple times to make sure you have everything cut that needs to be cut for clearance issues. Good Luck.

 

wow that sucks, everyone i know of thats put on headers hasnt had as much trouble as this dude

 

i have a digital camera but i cant get it to import the photos onto my harddrive....so i took so regular pics...i have to burn up the last few pics in the roll so i can get them developed....

when i post them up you guys are gonna ****....its really twisted up....if i can ill get a pic of my panhard bar and show you were it wrapped around that.....

as far as the collectors on the hedmanns tucking up to good...im sure if u use the s extentions that will solve that issue...i have to wait till the 1st before i can order anyhting....and if u gotta raise the motor to put um in then fu(k it....i dont have the resources for that...its always somethin with this fù¢kïñ car

what about the dual exhaust on the stock manifolds for now?

 

F-crazy,

So, are you going to go ahead and put the Heddman long tubes on despite the clearance issues with the slave cylinder/bellhousing? Oh yeah, when I tried it, the driver's side header hit the a-arm mount on the chassis, also.

 

if thats that has to be done then ill do it....but if u have to raise the motor and grind the a-arm a little then i cant do it....i dont ahve the resources to do it on the street in NYC...and i dont have the $$$ to pay someone to do it......
so i may just get the dual set up goin on the stock manifolds for now with pre bent tubing from a parts store...then do the headers when i can...

my "N10" is shot so that has to go no question

 

I got the S extentions with my setup to. I hope I dont run into to many problems. Even if the exhaust isnt perfect its gonna sounds great and you cant beat the price....

headers, mufflers (flows), s extention, H crossover...~270$

 

im going w/ hooker aerochambers, flowmasters sound good, but they hurt scavenging

 

Damn lots of problems with clearance from these headers. Im gonna do the install with the motor out so maybe mine will be a tad bit easier :::knock on wood:::

 

redflashblue, I got a pair of 2.5" aerochambers sitting on the garage floor. you can have 'em for cheap if you want. they have some scrapes but nothing major.

and yeah, the hedmans are a nasty install. if you do it outside everyone will hear you swearing

 

there is a feller on here that has them... he has pics of his exhaust and it looks very simular to fast thirdgens...........

the thing i cant figure out is were everyone says it hits??? the length it comes down can be solved with s extensions from hedman.... but where else does it hit???

 

i found the pic of the dude with the hedmans....... they look like they come down far enough to me.....

 

I just noticed this by your pic, but it doesnt look like the headmans are equal length, and on my hookers look like they are. I just hadnt realized that before.
