CA Header, XTC DP with cat 2.5" and stock cat back exhaust. didnt go crazy on the throttle tho. hope you guys like it

EDIT: Last acceleration was with window up, the rest is down
Sounds really good. I think stock exhausts are 2.25" piping. Correct me if I'm wrong, but this should sound downright mean with 2.5".

stock is 2.5 with a small section thats 2.25... im getting that section swapped out with 2.5 and getting a borla muffler... saving about 150 with that too

I'm thinking of sticking with the stock cat-back as well since swapping it out seems to yield the least results for exhaust. I'm glad to see that the CA shorty and DP with stock exhaust still sounds nice and mellow! I have them sitting in a box for now til I find out how I'm going to address the CEL when that pops up

the cel wouldnt affect anything other than loosing remote start...but you could find some tuning place to take out the code easily.

hmmm.... I swear I heard a whine when I was going down the track. I know it wasn't the camaro next to me cuz I beat him. Unless he had gears instead of a timing chain.
