The TRM is loud but it's really not too bad. If you have the silencer in it's actually very livable for noise. The TRM has an angle to it but not like on tegs and civics. I've heard the Apex N1 and that's VERY loud, personally I think it's louder then the TRM. As for the Tanabe DTM, I personally only care for DTM exhausts on German cars, however that's just me.
