Yeah, when I took the cats off it gets raspy sometimes around 2500 rpms, and pops from time to time when I let off the gas... BUT my cam is sooo much more pronounced I can live with the occasional popping

Does the popping while letting off only occur while the AIR pump is on? I removed the AIR system on mine and no more popping under decel. I also have a Predator programmer.

I still have cats and factory exhaust but I have a cutout. I get pops all the time and I love the sound, but my dealer told me that my cats are leaking because of low back pressure. Hopefully it won't matter soon because I'm getting test pipes and losing the cats.
