Andris is a r i c e r ! Fake tips!

Just messing with ya...I guess I missed the part about redoing the exhaust later. I kinda figured you might be doing that, just forgot to add that when I asked. I pay keep it. The minimal weight wouldn't give you any track benefit.

askulte.....next time they hassle you at the track just tell them to test the rear outlet. Then subtract what they hear out of that one, from the front one and you should be legal!

That looks kick a$$...good job, first side exit I seen that I realy like!
Off topic though what kind of wheels are those and could you tell me the size and off set? Those are just what I am looking to get for my black trans am.

They are CCW lightweight 3 piece wheels, originally for the SCCA T1 C5 Corvettes.

17x10 Front, 7-1/2 Backspacing, 11-1/4 Total width with sidewall bulge
Originally for a C5 Corvette

Dbl spacer (.140 each) still too tight, leaves 3/16" clearance against trailing arm.

With one washer and two plates, it barely clears the top. 7/16" total. This has 5/16" clearance to edge of wheelwell.

Need:
9/16" thick spacer
5x4.75" Bolt Circle
70.3mm centerbore, at least .350" deep

Specs from CCW, if they are the T1 race wheels
2.785 centerbore
Non-stainless hardware (gold colored coating) with nuts on the outside
Wheel halves welded together
Front - 17x10, 7.5" backspace, 50mm offset, 18 lbs
Rear - 17x11, 8.25" backspace, 56mm offset, 19 lbs

Plenty of ground clearance.

Lime Rock Park had an 83 dBa sound rule, and I was concerned about passing it. Dave Zug and Mike Davis helped fab this baffle that was tack welded to the exhaust. It aimed the sound at the pavement, and it worked like a charm. Stuffing the exhaust with steel wool was our next temporary option, in case this didn't work.

that is just amazing the sound is just incredible what kind of engine you got in the Z oh and another Q did u just run headders and straight pipes?

wow...sweet...im thinking of doing this since my dp is 4 inches and i cant fit that under my iroc....where did you get these ....any help would be greatly appreciated....i have a topic in the exhaust section thats fresh from yesterday if you want to chime in anyone...thanx again...

87_GTA_5.7 · 02-18-2009, 04:48 PM

Sorry to bring back and old thread..but How well would this work with Subframe connectors? Does the Blue Iroc have them..its hard for me to see or tell. Iv got a pic saved on my pc of a nascar style set up but I think I need to run a muffler of some type..mangapack or something at least..Kick *** car love the wheels cant wait till spring so I can order me some!

askulte · 02-18-2009, 05:49 PM

I'm running Southside Machine SFC's that are stitch welded along the rocker panels, and there's a Dynomax Ultraflow 3.5" in/out muffler to quiet things down.

I now know how im going to do my exhaust Thank you askulte.

87_GTA_5.7 · 02-18-2009, 10:53 PM

Sweet thanks man..Kick *** car..I love to see more pics of it..been on your page but dont see many with teh CCWs

Pingu 2.0 · 02-20-2009, 12:03 AM

awesome car! i was looking into dr. gas boom tubes and doing something like that but i just ordered my mufflex 3.5" catback w/ spintech

P.S. where abouts are you in west hartford? i'm over near sedgwick middle school. i want to eventually do a t-56 swap and such. where do you go to dyno/tune in the area?

87_GTA_5.7 · 03-04-2009, 10:06 AM

How does this "sound" with out having an exact picture. Having two Boom Tubes one on each side? Come out of the Headers (longtubes) wiggle jiggle whatever has to be done for the Tranny Crossmember with Oval 3.5in into a pair of Magnapacks or just some Magnaflow Mufflers, Then turn 45ish and go behind the door kinda like askulte. I found a pic that gives me an idea under the car.. could but shorter pipe then into boom tubes and have them stick out about an inch or 2. Runing it under my subframe ties? Ok doenst sound all that bad to me..but Wont they boom tubes sit odd and run up hill, My BMRs are Big and Boxy 2x2 Boxed, So..my cage/welder whatever you want done guy came up with this, Cut my Subframe or notch it and run it through the Subframe and then him weld it all back together and add bracing. IDK Im worryed about streight in the subframe ties now. But I like the idea..Let me know how that sounds

Nascar boom tubes?.....heres the exhaust off my Winston Cup car
