Apexi WS!!!

That N1 "Style" muffler is gonna be loud as hell... and probably resonate inside the car while your crusing down the highway giving you a major headache!

The Apexi WS has a 4" tip on it, not too big, not too small.

Trust us, if you want quiet, save up some $$ and go for a WS, you will not regret it!
