I’m still running stock manifolds with stock cats with the Gen3’s and the Fast Intentions Cat Back. With a tune she’s at 320 WHP. 50 WHP over stock!
I know it’s nothing compared to what the FI guys are pulling, but it’s my daily driver and I can tell you, you will IMMEDIATELY feel those 50 extra ponies. Not to mention there’s no more throttle lag.
I had Z1 do the installation and uprev tuning. All in price with parts and labor was just north of $2000.
Major improvement for minor money. Your already ahead of the game by doing your own wrenching.
