I have a 2011 murdered g37s sedan. I was told I should customize my exhaust because it would be cheaper and I can pick a sound I like. I've done research and everyone loves the Fast Intentions but I want something a little louder when revving and something that is deeper when idling but roars when I hit it. I'm not sure how many parts I should get to customize it. I've seen some good things about the Magnaflow mufflers though.

 

Welcome to the site Jake, moving this to the Sedan folder, check the Exhaust sticky on top of that folder for good info & sound clips.

 

This is a great sounding exhaust. He did 2.5 catback and has 2 chamber race mufflers.x 2 of them (no resonators)
