Got the SLP loudmouths put on. Very easy install and GREAT sound. Had the Pro Chamber with stock cats installed, didn't give me the sound I was looking for exactly. Gave it a deeper note but took the "bite" out of it, car is actually quieter now but still louder than stock. Car feels a little sluggish now also. I have done no other mods to the car, I'm thinking a CAI and a tune will wake the car back up. If I were to do it again I'd eliminate the cats or get high flow ones.
If anyone can help with posting sound clips I have vids of the stock setup with SLP's and then SLP's with the loudmouth.
