Re: Hi Flow Cat Needed
There are many high-flow after market cats available that are direct fit--and aren't terribly expensive. I'd suggest new over used, but that's just me.

Re: Hi Flow Cat Needed
Also noticed someone mentioning that they couldnt pass emissions w/ a hi flo cat. Whats your thoughts on that. Will hi flo cats make it harder to pass emissions?
