*update* Installed the 3" catless DP and it's hardly noticeable. Like zuulmusic said, it's more "raw". Sounds nice.

Well after a few days of driving with the DP, I've decided to remove the ZZP pcm for the stock one. Not sure why but the DP didn't help much with my KR. I was getting between 4-5*. Took it out for a test with the stock pcm a few times and my car hardly has any KR now. The only drawback is the coolant temps are now a little higher than before.

And here I was thinking that 4-5* KR is acceptable. That being said, I understand any KR is a performance-killer. I, for one, woulda kept the tune, but thats me. Glad you're happy with the exh note, though.

Glad you're happy with the exh note, though. 4-5 degrees on a stock car is fine. When you start dropping pulleys, the knock becomes more of a problem. 4 degrees of knock with a 3.0 pulley is a LOT worse than 4 degrees of knock with a 3.8 pulley
