hi guys
i have a 89 RS and is lowered, i just finish doing a motor swap and i bought hooker super comps, i havent see a lowered car with long tubes yet.. anybody dont it before? if so can you post some pics?
i'm thinking of buying mufflex Y pipe and they catback. but i think the Y is going to be to close to the ground... any suggestions...
here is a pic......

 

WOW! That is low. I too would like to know if anyone else is running a lowered car and long tubes. Also, what header back set up are you using. A search might help to for us! Oh yeah, any pictures of the car itself Revel?

 

man dude those hang really low. i think you should take them off and say give them to me?!

 

You might beable to lift the engine up a little bit, maybe different motor mounts?

 

if he raises the motor the headers most likely will contast the floor pan which is not good. i said they hang low just because he lowered the car.

 

if he change the engine mount, he may need to "mod" the body otherwise the headers will HIT in several places.

My car is not lowered and i think these headers are preaty low... still my exaust have been well done and the lowest part is the actual headers flanges.

Say you'd have a Manual car you could make the exaust pipe goes up the trans crossmember, on each side you can fit 2" nicely, posibly more, but i know for sure 2" is no prob...
If your Auto, I have not seen under an auto fbody lately so i dont know.

I suggest you try going around open headers to see if it hits (i know it's noisy but, hell, you cant heard it HIT!!! lol, you need to look at the flange after your trip is done to see any scrachts!)...

I dont think longTube and lowered car is a good idea. You better have super stiff suspension if you still want to try it. Selling your headers an getting Shorty would be better.

 

Im puting them in my lowered vert when I drop the new motor in.

What oil pan is that you are running? looks like a aftermarket one.

 

what I would do, is while i was still building the motor, use heads with raised exhaust ports...

you'll have better heads and the longtubes will be higher up..

the downside is, you are jus going to have to hammer/grind/ect on the car to make them fit. some people have a prob with doing that, others dont.

 

also, new mounts will raise the motor too..

 

yes is a moroso 7 quart oil pan, im running poly motor mounts
is a 383 stroker with dart heads miniram, accel gen7 dfi crower cam #00426 and high rev kit...
is super louds on open headers. i havent drive the car yet cause i got the b&m megashifter and the super long shifter cable got melted cause of running the motor without exhaust.....
and icant get shorties cause of the oil pan....

the car

 

I was thinking of oval pipes? to fabricate an oval Y pipe and then follow the same factory exhaust route with oval pipes??

 

Verry nice...

Im doing true dual with Dr. Gas oval and a x -pipe
with spin tech muffs.

Hey where in PA are you? Im right on the Ohio/PA boarder

Should've got the Headman LT's. They're tighter to the car and don't hang as low. - You're deffinitely going to have to be careful going over bumps. You're fine as long as your front suspension doesn't drop when you hit a bump. - I'm lowered and have Lt's, but I have Headman's, and I don't think I'm quite as low.

 

im in Horsham, like 30 mins from philadelphia....
i was thinking of running the mufflex Y pipe with their 4 inch catback with spintech muffler.

 

Nice ride Revel! Yeah, about the exhaust, i think i am going the same route. Pretty easy to do instead of paying a shop you don't know(well for me anyway-without the "hookups") to do a custom $$$ exhaust. Should be very little modifing to get it to work well. I am sure if you made a custom set up it would hug the chassis a little better then that mufflex setup. Oh well, just gotta be careful and not drive into Philly that much, huh! lol Good luck

 

What spring kit are you using? Eibach Pro? Eibach SportLine? Just curious because, IMHO, that looks way to low to run on the street. You'll bottom those headers out in no time. FWIW - the Mufflex Y-Pipe sits LOWER than the headers.

That motor is my dream motor. I have a thing for the miniram on any small block. Anyways, I have shorties but since my car is lowered so much I have clearacne problems with my cat and I pipe. They hang just about as low as your long tubes look to be. If I go slow it doesn't scrape, but I have to be carefull around speed bumps and what not. Just control your advance and you usualy don't have any serious problems.

 

Careful.... $hit, I plain turn tail and run when I see a speed bump! And I have shorties (SLP 1.75s).

My "test pipe" in the stock cat location isn't really a problem at all. MY lowest points are the Spohn T56 crossmember and the S&W Racecars crossmember that comes with their SFCs. With the Pro Kit in my car, that S&W CM has about 3" of ground clearance at its lowest point (it goes UNDER the I-pipe).... That Spohn CM is a little overkill IMO, but I guess ya can't complain when something is over built when it comes to strength. It could be a little better engineered for ground clearance though.

I wish I could run LTs but it would be big $$$$$$ to hack up the floor and/or bend up a custom Y-pipe that would flow well enough to make it even worthwhile in the first place to go LTs.... So the SLPs have a home on my car for the time being....

<-- *wishes he could run LTs *

 

I run the same 7qt Moroso pan (#20180) on my 1" Hotchkis lowered Z with SLP 1.75" shorties.No clearance problems outside the normal with the shorties and the pan.Cutout hits before anyother part of my exhaust.Your is way lower than mine..good luck with LT's..I would highly recommend going shorties if you plan on driving it at all.

On a side note..sweet as* car.

 

hey guys i need some help locating a one piece 3 inch intermediate pipe that will fit on my 3 inch slip on flowmaster highflow cat and goes into my 80 series single in dual out flowmaster muffler. i ahev a huge hole right as the pipe enters the mufler on the bend. pain in my butt i dont know where i can get one i have checked flowmastermufflers.com and i get nothing. i do not want a 3 peice setup either. so if anyone has an extra they would like to sell or knows where i can buy one let me know please.

 

spring kit are sportlines.. i barely drove the car last year i put 600 miles and that was with the 305 TBI.. i dont wanna put the stock springs back cause is looks so high, for me doesnt look aggresive.... my oil pan i dont know what part# is but i had dynomax shorty headers on the 305 and i test fitted them to the new motor and the oil pan was in the way.... plus the Y pipe didn't fit between the oil pan and the crossmember... after i finished the exhaust the car is going to the paint shop this winter

i was thinkin of somehow making a Ypipe out of oval tubing...

 

this is the oil pan

 

Ahh..I see now.I thought you had just the deep Moroso pan..I never saw the kickouts on there..yeah I know of no shorties that will fit that style pan.

 

Why not try the IROC or WS6 springs? I think they lowered a stock camaro about a .5 in or something like that. I would try that before lowering it too much.....and hitting an "unknown" bump or dip in the road at speed. My buddy has a 95 Z that "had" L/T's on it....till he hit a hole in the road at night going about 35.....wasnt pretty. He ripped the header off the head....almost went through the floorpan. Just something to think about. Great car though!!!.....good luck

 

Should've got the Headman LT's. They're tighter to the car and don't hang as low. - You're deffinitely going to have to be careful going over bumps. You're fine as long as your front suspension doesn't drop when you hit a bump. - I'm lowered and have Lt's, but I have Headman's, and I don't think I'm quite as low.

true, the hedman l/t's do not hang below the trans x-member, it actually sits lower than the headers themselves, oh and they are cheaper!!!

 

I have a similar problem... my car is also lowered and right now, the one pipe is routed under the floor and is waaaay too low to the ground. I am using Heddmann long tubes and Eibach Pro Kit springs. I have yet to go near a speed bump, they are my enemy.

 

i have custom made lt's with 4" piping and i don't have much of a problem with my 3/2 drop. i had the car dropped 4/3 but it definately wasn't good for any sort of road that was slightly imperfect.

i wouldn't recommend running this type of setup unless you have alot of power. shorties and a 3" are more then enough and will work with just about any practicle drop you could want to use.

when i set the car on the ground i have a little more then 1/4" of clearance for the y which is undriveable.

good luck with hit.

 

Who made your LT's were they made from scratch? what primary size etc? is it a custom Y-pipe into a single 4inch like the muflix(sp) setup?

 

i suppose it's similar to muflex although i haven't seen the muflex setup so i couldn't tell you. it's all custom made with exception of the spintech muffler.

 

I just bought the mufflex y pipe yesterday... im going to get it install on by tuesday.... so i will be posting pictures soon..
if is too low i'll be swaping springs soon

 

yea.... kinda sucks...

but what im doing for the lowered look is using a bigger overall wheel, and then using lowering springs to bring it back to stock height.... so the clearance is the same, but theres no wheel gap.


thats my idea that is... when i get around to buying wheels and tires, i'll let ya know how it works out

 

interesting theory.....doesn't work quite well but you will get rid of the gap. that's similar to a old school monte on 20" wires...wheel gap or not it looks a bit odd, i like the idea though so i hope it works out for you.

yeah for lowering my y had to be almost ovaled in a sense in order to give me clearance. not much but a little.....has worked well so far.

 

lol, not nearly to that extreme.......


my cars current height is "settled" a lil lower then most 3rdgens.. even though springs are stock..


im going to bring her to that height... so its like a inch drop with 17" rims, just a lil larger tires then normal plus size.... i might do 18" rear, might not.... im still deciding on my rim design...

having a hard choice between OEM style vette wheels, BBS style dished, or good ol 5 spoke designs....


all i know is, i want a 11" wide rear tire, and a 9.5" front.

 

well 11's won't fit without minitub or at least a good hammer and roll. that is if you want them inside the fender.

good luck with your choice.

 

they JUST bearly squeeze in there..

and its a VERY SMALL amount of hammering... you have to trim and roll the lip though..

 

glad they work for you....my car would not fit 11's as 10.5's just fit nicely and 10's are a very clean fit.

 

I'm in the same boat with my 91 Z. My blown L98 will be swapped out soon (est end Nov) and a blown 427 will be taking its place. I dont know exactly how much power it will make but I do recognize that shorty headers might be a restriction on the exhaust end. I want to run long tubes but then ground clearance becomes an issue. Like Jeff, I'm running 18's and adjustable suspension for a very aggressive stance. The car is daily driven and long tubes might become a problem really quick on the uneven roads here in Hawaii. I posted about it before and everyone pretty much said if I think ground clearance will be an issue, run shorty headers. But I cant stand the thought of my exhaust holding my motor back, so I had to figgure something out. I've contacted some Stock Car Racing related fabrication companies over there on the mainland US. I dont have any answers yet, but they are looking into what will solve my problem. Stock Cars are very low and produce alot of power. Their exhaust systems are designed with maximum flow and maximum ground clearance. I doubt there are systems made for a 3rd gen F-Body, but they are checking into what will fit. I know this exhaust (if it happens) will not be legal, and it might cost alot, but I feel it will be the best solution. I'm not really worried about ground clearance over speed bumps at slow speeds. I'm more worried about ground clearance when going 150 mph on the freeway and some freak bump comes out of nowhere.

But if the Hedman long tubes dont hang lower than the transmission crossmember then that might be good enough. Does anyone have any more info to back this up? If the crossmember is the lowest point of my car I'll be happy. Thanks for any info you have!!

 

you should have a lot more on your mind than that if you are doing 150 on an open road! Just because some of your freinds with their supercars can do it, i would think it would not be in your best interest to be following along. Just my opinion unless your whole car has been redone, b/c these cars were not built for it, at all! But yeah, back on topic, if you can find a way for clearance and an "aggressive stance", please share. good luck with your plans

 

don't know about 150 but 145 is fun!


i don't think you would have a problem so long as you stayed to a 3" design. the only reason i have any problems is because of where my headers meet the collector. 4" is impossible to not have some sort of problems. even still it works but i have clipped things that just can't be helped.

 

heres is the pic, im getting the rest of the exhaust system by the end of next week, after that i will start to drive the car....

 

wow that is low...

edit my above post to 170.

 

I agree that is low.

and what was the 170in and how do you know it was actually 170?

 

Damn man, you will have to drive the car around like you have a flat inorder to avoid the simplest road problems. And what fun is that? There are a few kids around here with thier cut springs in thier civics, and let me tell you, you sure as hell can spot them down the road in the middle of the night!! lol not very practical for a daily driver, just be vey carefull! Oh and Kandied, did you top her out or was there still more left in her??

 

right now the car is at 92 efficiency and i could still pull....i'm working on raising that.

were working on a few more tunning issues but the fuel is programmed to shut off at 200 on the chip. that's what i'm aiming for.

 

a little too fast for me......

 

Revel, what part # Moroso pan are you running and do you have a windage tray? It's kind of funny, our cars look real similar and have similar engines. The main diff. is my car is red and has the stock hood.

Joe

 

Joe, i really dont know the part#, the only thing i know that is a kick out, 7 quart , pass side dipstick.... with a windage tray. you have pics of your motor?? have you driven it yet?? im waiting for the rest of my exhaust, and then i'll be tuning and driving the car... i cant wait to drive it with the new motor..

 

Hedman longtubes are a real nice fit actually. I was suprised. I had them before. They fit perfect with no denting or anything. I liked them. I real nice header for the price. I wanna get some and get them coated this time. Im tired of ugly headers that are painted....it never lasts.
