I'm of the impression header install on this car will be a PITA? If not, I'd be interested. Inconel LT headers would be especially interesting

I want something turn-key, easy install on the full exhaust system.

I wouldn't want any louder then a stock system, I would need to see the weight savings to determine my budget. I do not think I could spend 5 k but was expecting 3ish

Why its like the LS3 in size and that is not hard at all.

I'm specifically asking for:

*OE fit/finish
*Header-back
*Retain OE exhaust valving
*OE decibel levels
*V-band flanges
*200 cell HJS race cats or equivalent
*O2 bungs

I would guess these systems would come back at $3500-$5000 lest anyone not realize the likely cost here.

Not a z/28, but as a ZL1 owner I would be interested too.

Good deal, great minds think alike The interest level is there and will motivate some manufacturers to step up to help us out and make some money at the same time.

I'll encourage any manufacturers I make contact with to post here- direct to consumer marketing, it's a beautiful thing.

NOTE: IIRC, the LS7 uses 2.75" and the others use 2.50" plumbing.
If you intend to move the HP curve upwards, I'd do 3".

I could be wrong.

I do not see the Corsa Ti system we used in 2003 in their catalog. But they are still working with Ti.

This sounds like a great project. On my car, I'd like to wire a switch to control the exhaust valves (that open under full throttle) so that I could keep them closed -- at tracks like Laguna Seca -- if noise becomes an issue. Hell, what am I saying?!? At Laguna these days, noise is almost ALWAYS an issue!

Unobtanium would be great, but he is up here in Canada. His custom work is second to none.

I have replies from both Unobtamium and Litespeed Racing now, both are enthusiastic to do this and have wanted to do a Camaro Titanium system for a while. I am refining the proposals a bit before presenting them to the thread for choices to be made and purchase commitments by buyers to be done. One of them is looking for 5 people to initiate a "group buy" and that should be easy enough to achieve based on what I see so far.

I also have a IM in to a GM person to determine what the spec is on the OE catalytic converter. There is mention in the Z/28 literature of it being a high-flow cat, and if there is no efficiency to be gained by going to a 200-300cell aftermarket cat, then that saves big $$ on the system and allows for the focus to be on cat-back vs header-back. If OE is high flow, then the system will for all intents be only for weight loss, anything cat-back in my experience is negligible in regards to HP/TQ gains (especially so on the Z/28 system I'd bet money).

We need to know what the db is at WOT to see if it is even an issue. My suspicion, like yours, it it will not pass 90-92db so may need a workaround of some kind, whether turnaways or a manual valve control as you mention.

Does someone know for a fact how the Z/28 system operates and can post a diagram of the vacuum/electrical actuation system?

Good to get a recommendation, thanks! I received a reply from him but need a Z/28 up there to build off of, who here is near to Calgary and interested to help?

I talked to akrapovic at SEMA last year. They said "What's a camaro?" (not really)

I'm not sure how many Camaro owners would be willing to spend $5000-$6000 on an exhaust, but Akrapovic sells a ton of them for BMW's, Sportbikes etc...I wish I would've stopped by their booth!

+1 for the "What's a Camaro" joke, I can totally picture them saying that lol

Still an oldy but a goodie. For db restricted tracks, the de facto standard is still the inexpensive and lightweight SuperTrapp:

Checkout this thread http://www.camaro5.com/forums/showthread.php?t=318683.

Its the same for ZL1 and 1LE. So i assume the Z28 won't differ.

As I assume you Z/28 guys have similiar issues with the belly pan, it would be good if the headers wouldn't require a trimming of the belly pan.

If you know a guy good with TIG:

http://www.titaniumjoe.com/index.cfm...0:0.025:WELDED

Super Light Weight.

Don't even try to bend it. It will fold. For bends, use pre-fab thin wall stainless and clamp together. Or pie cut the Ti tube and weld.
