I have the volant intake and FM40 dual out 2 1/4 turned down right behind the rollpan. Sounds awesome outside and doesn't resonate badly at all inside. People say they can hear me pull into the parking lot or up to the house or whatever, but you'd never know from the inside and I've never gotten any noise complaints, so I think it's almost perfect. Only thing is (maybe it was just in my head, but..) I think I lost some power/torque cause the exhaust isn't tuned for my setup, but oh well, no biggie. It's just set up to get me by til I have the time/money to do all the radical stuff I wanna do to it. Sorry, no sound clips though..
