Hi there: I'm looking for an aftermarket muffler primarily, but would also consider a cat-back system. Let me know what you have - I don't want anything loud. So far I've been primarily looking at muffler only setups with a possible resonator delete - Magnaflow, Rogue Ikon, Scorpion, Dinan, Vibrant, BMW Performance, Remus. I'm in the Philadelphia area. Let me know thanks!
