Question did you buy this exhaust used or new ? I have had 2 tomei exhaust my first one sounded like yours (loud ) but the muffler flew out in the Highway . Now the second one I got sounds really quiet . Both I got them used . And I really want this note back again .
Got it used, mine is straight piped from turbo all the way back, tomei exhaust and test pipe. I think if you were to get tubular manifold it would make it louder.
