Well, I have a 00' SI and I have the basics... AEM CAI, ractive full catback, and just recently a DC 4-2-1..... and i was looking for a GUESS as to how much hp i've gained, since i dont have access to a dyno....

Thanks everyone

 

Probably around 15-20?..

 

no guessin here please, go to a dyno! but it will be pointless b/c you neve had a baseline dyno done, sorry!

 

and no you def didnt gain 20hp

 

prolly like 5-8, anymore is pushin it!
