It really all depends on the sound that you want. If you do get test pipes, make sure they're resonated. However, my vote is HFCs. It shouldn't make much difference in which ones. I have the Kinetix. Just make sure they have the extra brace on them.

i like the deeper sound that i have with the greddy exhaust but its just not loud enough for me...so i want the deeper sound just louder..the test pipes would be better than the high flow cats for that right? oh and what do you do to trick the o2 sensor when you put the test pipes on so your check engine light doesn't come on?

We don't recommend that members commit a Felony by replacing oem cats [that have not failed] or in any way modify the emission system.

Just because it is rare to get caught and be prosecuted doesn't mean it is not a felony.

What about in places like Florida where no one cares (otherwise meaning, no emissions testing) ?

Do you really have no emisions testing in Florida ?I have been dealing with the smog police since 1976.Even with that said i would still go with high flow cats.I think your engine managment will work better.
