i have a 92 vx with d16y8 swap and was wondering what is the best hi-flo cat for my car. right now i have dc 4 into 1 headers a test pipe and vibrant cat-back. the reason i want a cat is because my car is way too loud and sort of buzzes

 

get a carsound or use a stock cat. that motor might not really benefit from a high flow cat.

 

anyone else

 

its still gonna be loud with a hi-flow cat...just legal

 

alright thanks
