I just got rid of my '08 with a 4.8L, it didn't have AFM but I had put a borla muffler on it and a single side exit and the drone was bad.

I now have a different '08 with a 5.3L that does have AFM, I'm thinking of using the GMPP single side exit exhaust or maybe MBRP. I believe GMPP is made by Corsa? I bet it sounds decent.

Either way the AFM is going to get deleted in the future, it's hardly worth it.
