Pontiac G8 2008-2009 - Corsa Exhaust dyno quarter mile

ok i jus ordered the full corsa exhaust and i was curious if anyone know what i would be able to do at the track and what kind of number i would be able to put down from the crank and to the wheels.

With just the Corsa? 305 whp and 13.7

Might want to look into a tune...the Corsa isn't gonna give to much of performance boost.

yea i wanted to get a tune also but i dont want to void the warranty u know? i will get a cai soon would that help much for the track or hp without a tune?

If you buy an HPT you can slap the tune on there and copy you stock one and if you take it in to the dealer, just copy your stock tune in there.

yea just doing muffs isnt going to do much...

The Corsa system gave me 5 rwhp more than my factory ws6 catback. The ws6 catback is worth about 5 rwhp over a stock ta catback.

thanks man i am pissed the parts were sapposed to be here today but they said they are not gonna be here till friday now.
