I'm catless, it smells like raw fuel, my motorcycle doesnt smell like fuel at all.
I want to installal wideband because i suspect the diablo tuner is why its actually smelling that way, but no exhaust shop around will weld the 02 bung on because i dont have cats


I vote keep the cats

no cats here. You could save your stock parts so if you ever need them in another state. But as long as your here in mich,remove them. cats cost power and i would not spend the cash to buy new ones. My car does not smell like fuel with the tuner i use,but like ls cars i have a little rasp around 2,000rpm's. My car has a low rumple catback and my boy has a stock center mount ss cat and the cars are not loud.

One of the best things is it cuts down rasp. People add them just to do that sometimes

Thanks for the input everyone. I have decided to go with ARH catted y-pipe and their 1 7/8" headers.

Factory option. I believe it's known as the Y3F package.

good choice, I will be switching to a catted y-pipe here when I get the extra funds for it.

I'm wanting a much cleaner sound and less hassle if DOT ends up pulling me over.
