So I've always had my exhaust stock even now when I'm pushing over 600 rwhp. I've read that some of the guys on corvetteforum have made about 50-100 rwhp from changing out the restrictive exhaust out for a more efficient better flowing exhaust. Any of you guys do a before/after dyno on a stock exhaust vs a bigger one on a FI car and had similar results?

I figured I would keep my exhaust being that it is titanium and is much lighter than aftermarket exhausts, but if there really is a massive gain in HP/TQ from changing it out the weight difference would be well worth it.:beer:

Yes I am running a 8rib setup..

100rwhp by an exhaust change only? I think no way! More like 20-40rwhp or something as such for the FI cars.

On a car making 650-750rwhp on stock exhaust yes I can see there being significant gains maybe not a 100hp but I don't see why 80 hp wouldn't be out of the question. Espiecally because if u lose PSI u can pulley down to regain the boost u lost..
