I can't put up with the racket coming from my 1JZ anymore. Its too loud at idle, driving and drones a bit at freeway speeds. Curently the exhaust is 3.5" with a single straight through Dynomax muffler. Today I had a 3" hotdog fitted but this made no difference whatsoever. I also got the exhaust guy to test a 3.5" dynomax resonator by slipping it over the tailpipe, but this made no difference too. Is my only option going to a conventional type muffler and losing a bit of powah? Any other ideas?
What exhaust systems are you other 1JZ guys running and whats the sound like?
