I have a Tanabe Hyper Medallion full cat on my RSX and I love it. It's not too loud at all. The exhaust I had on my integra wasn't a Tanabe and that thing was the loudest thing ever, set off car alarms and crap, I hated it, heck someone rode in my car and said they got car sick fromt he vibrations of the exhaust..but this exhaust on my RSX is great! :thumbup:
