We are talking crank....for get the catback...test pipes and the pop charger or stillen cold air.....that should put you at 360 crank....ok do the catback free flowing the better.. but get it custom. As it wil be far cheaper and you can reuse the stock tips... 500 max....
with the cats gne a free flowing muffler...and a cold intake i can feel 15 hp in the seat ..this is more.....so i guessung at 360-365...which is older C5 vete power...the torque come up but not enough to feel v8 like....so you rev.
Good luck..!!! Pm anytime
you can have custom work done far cheaper....
To be honest, no I don't feel much difference. I'm sure it's added the claimed 10-15hp in the upper range, but it's hard to feel that on a 332hp car. I think in order to feel a gain you will need to combo the exhaust with an intake and some HFC's. It's a combination of parts that will get you the most gains. :-) it does sound a bit better though.
