Cat converter suggestions?

[darionmilton]

I have a 2000 gtp glasspack as res..
Well my cat is clogged and I was wondering if I should straight pipe it or get a high flow cat? No mods yet. Btw

How much will my mpg suffer?

gas mileage will get better since your cat won't be clogged up.

Buy a quality cat if you have emissions.

Most high flow cats will end up setting a rear o2 code because of how well they flow.
