Re: Which hi-flow muffler and cat do you like the best? (Surfingdude81)
with cats, ones that claim to be high-flow and still pass emissions are just as restrictive as the stock ones. if all they do is check to make sure you have a cat, just gut the one you have. if they test the emissions, then stick with stock.
