I have my corsa touring exhaust sitting in my appartment and I will be installing it pretty soon, but I was wondering if it will even increase power, since I don't have a header or DP to go with it. I guess all I want to know is, if you benefit from exhaust upgrades only when it is full exhaust, or can you benefit from upgrades even if it is only a part of the full exhaust system?

 

no, just send it to me then. i'll pay shipping.


you should get maybe between 6-10 hp from a catback on average.

 

Alright, Its still new in box, so i'll just mail it on over... whats your adress?

 

it will make a difference. put the bitch on

 

Oh its going on either way lol... I was just curious cause i read something that was sorta saying it wont do much..

 

The Corsa and the GMPP are very similer in gains and the GMPP system shows an average of 12 to 15 HP over the stock factory cat back so you should be able to see gains of around there.

 

Say what?

Look at Corsa's website... the gains should be posted there.
