Ok guys, i am getting a loud mouth, and an slp y pipe, so i figured i woudl get the cat to go along with it. Now what size cat shoudl i get? And will this cat in the link i have given you actually work? And on top of that do i need one of those 02 sensors like it says? I dont know much about cats. How much hp does a cat like that free up?

Thanks,
Keven

Get a 3" MorFlo (Carsound) Universal cat for about $100 and a rear O2 simulator and you'll be set. How much HP will be freed-up? That's up for debate, but I wouldn't expect more than 10 if that's the only restriction in the system (remember, the stock cat flows pretty well as is).

Just my .02
