Ideas on replacing stock cats
 

My current exhaust setup consists of AAM midpipe with AAM short tails. I'm now looking at replacing my stock cats to compliment my exhaust system.

I assume that even though I have AAM parts installed, I can install other manufacture cats replacement parts. I say this since my midpipe aligned with the stock cats.

So, what do you think I should go with? My main concern is that I'm able to pass state inspection when due.

Any cat of your choice should be fine. Comes down to personal preference I guess. I went with Z1 HFC's due to cost and availability. Plus I have always received excellent service from those guys.

how does the AAM short tails sound? i was thinking of doing the short tails with test pipes myself, just looking for a nice aggressive tone and not so much HP, 12 Horses isnt worth 1500$ to me. i would be interested in hearing some clips when you get it put together!
