leeperryracing · 03-25-2008, 11:43 PM

more pics...

joshh44 · 03-25-2008, 11:46 PM

looks pretty good i think.
i be more careful on speedbumps.
your oilpan looks pretty scraped up. the headers look like they sit lower so i watch out for bumps and stuff.

leeperryracing · 03-25-2008, 11:49 PM

guess what, more pics.

joshh44 · 03-25-2008, 11:51 PM

where did you get thos seats?! i like em!
and i also like your doorpannels!

im looking in getting some racing seats. where did you get yours and how much did they cost?
i really like them.

leeperryracing · 03-25-2008, 11:51 PM

just a couple more

leeperryracing · 03-25-2008, 11:59 PM

the very last two....

Orr89RocZ · 03-26-2008, 12:11 AM

exhaust looks pretty good i think i'm gonna do something very very similar

I have to see how much clearance i will have tho. Those longtubes look to hang as low as hookers and i was hoping to tuck it up abit more than what it looks, but its hard to say just by looking at pics

how is your ground clearance and is your car lowered at all?

leeperryracing · 03-26-2008, 12:21 AM

the car is lowered courtesy of hotchkis springs that advertise a 1" drop but it looks more like 1.5" to me and everybody else who always say the stance is killer. Ground clearance is suprisingly good, just a TINY BIT less than the edelbrock shorty y-pipe deal I had before and of course these mufflers hang a little lower than the flowmaster I had in the stock location too. It'll take a pretty nasty speed bump to rub though.

Orr89RocZ · 03-26-2008, 12:40 AM

nice! my car is lowered about the same and i need headers. Seems to me i'll be getting dougs as well and running some sort of true dual exhaust. I now need to either cut the subframes or crossmember to fit them better. I'm thinkin spohn crossmember mods will be necessary to try first before i cut the cars frame

mw66nova · 03-26-2008, 12:32 PM

that looks AMAZING! i'm thinking i'm gonna do a k-member first, but those dougs headers are definitely on the agenda over the next year.

Hey man.... that looks good, id like to do true dual and then come out separate ways and go in front of the tire... with a thin and long tip...kinda like nascar does there underbody with the exhaust, u know like the ford lightnings did the exhaust on one side.. id like to do both sides!

chevyrules85 · 03-26-2008, 06:44 PM

first of all, very nice exhaust!

haha second im thinking of doing the same thing with hedman lts, just wondering is that mandrel bent or crush bent? from the pics it looks crush, and what size pipe did you use? did you do it all yourself? or did you have a shop do it? and if you did, what did all of it run you? also what kinda mufflers are those?

leeperryracing · 03-26-2008, 06:55 PM

put it on the dyno today(free hookup

) the exhaust made a whopping 21.7 whp more over the 1 5/8 edelbrock shorty y-pipe, full 3" no cat to a flowmaster crossflow muffler setup I had before and sound a LOT better doing it too!!! that X-pipe with the magnaflows=VERY deep and throaty. So on motor it made 358.4 whp@ 6400rpms(could probably get more if i screwed with the carb a little more) and 367rwtq@ 4500rpms. On a 125 shot it made 476whp@ and 485.6rwtq but I know I can get more because the air/fuel ratio was reading 10:8 at the top during the nitrous pulls

so going down to the local speed shop tomorrow to pick up a jet assortment kit and shoot for around 12:0-12:4 air/fuel ratio and that "should" up the numbers a little i think. I'll then head back up to the dyno and see what it does. All the runs were on shell V-power 91 octane, 33* timing on the bottle, 38* on the motor.

Orr89RocZ · 03-26-2008, 07:04 PM

wow thats a good gain!

leeperryracing · 03-26-2008, 07:05 PM

chevyrules, my friend at exhaust pros bended and welded up the tubes(not mandrel bent) for me and the mufflers are magnaflow straight throughs...could tell you the part# if i knew what i did with my warranty card. The shop is also a magnflow dealer and he suggested those mufflers for a 100% unrestricted flow, extra clearance and the bad a$$ deep bassy rumble especially with the 236/248 duration cam...it has a lope to die for!!

P.S- 2.5" pipes

Orr89RocZ · 03-26-2008, 07:29 PM

what is your motor setup if you dont mind me asking

haha, when is fast enough...enough?

Orr89RocZ · 03-26-2008, 08:03 PM

when your radial tire king and well into the 8's

Andy316 · 03-26-2008, 10:00 PM

Man, your car is awsome. Its like you crawled into my head and stole the ideas I had for my car and did them before I could. Everything headers, exhaust, seats, cage, dash cluster. Your friend did a real nice job on the pipes. I hope mine comes out as good as that.

chevyrules85 · 03-26-2008, 10:21 PM

so did he run into any problems running both pipes over the axle in that spot? anything that anyone else should watch for if they attempt this?

Stevo · 03-27-2008, 12:03 AM

Well i just ordered my dougs! Summit was backordered till mid april so i bought them through Jegs. $549 Shipped.

Thats a beautiful looking setup. I thought of doing something similar, but i think im just going to exit before the rear tires. Haven't decided completely i got a really good exhaust guy who ill just leave the car with him and let him do his thing.

Ive seen your setup done on a few 4th gens, thats gotta hang pretty low if you are right under the driveshaft. Do you have any shots from the side at ground level?

21rwhp gain with that exhaust setup is amazing! Bet you were happy to see that. Thanks for sharing the pics!

yea i would sure like to see some pics of it on the ground.. jus to see the ground clearance cause u said its already dropped an inch n half and u still have good clearance... i have the 2210 Hookers.. i wonder if the clearance is the same??

Orr89RocZ · 03-27-2008, 03:13 PM

it should be since the two headers are nearly identical and designed by the same person i believe.

leeperryracing · 03-27-2008, 08:33 PM

chevyrule, there was no issues to get the tubes over the axle, just bend them right I guess. Orr89RocZ my combo is as follows:

forged and arp studded 10:2:1 355ci
edelbrock performer rpm alum. heads 2.02/1.60(angle plug), rpm air-gap manifold, 750 holley DP, comp hyd. roller 236/248 dur @ .050, .520/.540 lift @ .050, scorpion roller rockers, built 700r-4 with edgeracing 9.5" 3200 stall, built 10bolt(moser 28spline axels, c-clip eliminators, torsen posi, 3.73s, ls1 driveshaft....), all the other suspension pieces except for a cross-member mounted adj. TA(getting one before the season starts). Anything else just ask.

mw66nova · 03-27-2008, 08:46 PM

hey leeperryracing, do you think that my little 305 (that runs 12.3/4's) would benefit from a 1 3/4" primary? i'm going through the traps right now at 6400rpms...
