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.

 

if a test pipe legal in your area, then go for art pipe. if it doesnt, go for berk hfc. however, just make sure you are patience enough to wait for the art pipe, ive been waiting mine for a month and not yet shipped out. hahaha

You would want a resonated test pipe, that way you get more volume of sound without the drone or rasp.
