I have these connected to BBK's shorty headers and a dynomax catback. No fitment issues but I did lose a bolt so make sure to re-tighten everything after a few miles. They will make your car louder but it's no obnoxious. The only thing you may not like is some rasp at 3k RPMs and up. It's gone by 4k but it's annoying. It really pulls in the high end but feels like I lost a bit of TQ below 3K.
