Lost power in take off after motordyne m370

I heard the file, that's rasp from the test pipes. It's definitely a common problem when installing on most exhausts. I had rasp for the first couple thousand miles with my long tube headers. Let some soot build up on the pipes and it will help quiet them down. If it still sounds like what I just heard, The best recommendation I can make is to purchase the Motordyne XYZ pipe with a resonator, but requires a Y pipe setup, which depending on which Nismo exhaust you have, may or may not work. Ben1620 added the Motordyne Y pipe / resonator and cleared up his sound. you won't have to replace your whole exhaust or get rid of your TP's. It's definitely much easier to install as well.
