hey guys, i apologize if I started a new thread, maybe theres an answer to my question somewhere. However, I have a nismo s-tune catback on my 03 6MT coupe and i wanted to get more depth and volume outta it..any suggestions? Berks HFC? Motordyne ART TP?

I dont want rasp, i want it to sound a little ballsier and meanier, deeper and louder..what would help me do this? Thanks guys.
