Wait, is the stock V6 exhaust kinda quite? If so then mine isn't stock...it's got a very nice rumble at 600 rpms and single exhaust. I know the tailpipe is different, so maybe the muffler is too. It's somewhat loud, but after the CAI the tone dropped and it rumbles now. I do love it =D. 2500rpms, it opens up, gets louder and echos ALOT off the houses.
