i think he is a little skeptical of your statement. 15 HP from a cat back sounds like a hefty estimate.

understandable. i didnt plan or expect such gains with it when i purchased it. since i bought the car ive wanted to go FI with it so it cant hurt to have a larger diameter exhaust. ive searched around for the few graphs i saw but i cant find them so im not going to argue the gains on 3" on my car.
thanks for the warm welcome 
ya like i said in the first post, alot of things have changed for me
welcome back
