I understand people like loud, it will be loud and aggressive without being obnoxious. MY Tanabe exhaust was rated at 93db though... pretty quiet when I'm not on the throttle. The second I tip in the gas, it opens up a serious can. I couldn't imagine LTH's/TP's with 12" or no resonators at all. I would purchase an insurance policy on my ear drums.
