Sniffer Vs. High Flow Cat

[Jaymatic]

I think I am going with a 3" in/out high flow cat but need to make sure of something first. I am running a 2.5" cat-back exhaust so I will have a reducer welded to the outlet side of the cat. I know that I will probably get an SES light but I will deal with that seperately if/when I get it. My worry is, will the sniffer get me or will I pass emissions with the high-flow cat? (that is with the SES light fixed)

I got a better emissions reading with my catback and highflow cat than my stock setup.

Same here.

ok sweet, I guess I'll go for it then.

Is there much difference between a 3" inch cat and a 2.5 inch high flow cat? Because I always see the high flow cats for like... 100-150 bucks, and I just bought a 3 for 45$

well the stock cat is 3" in, so I'd say we're better off with a 3" high-flow cat than a 2.5
