Just FYI, the RFL muffler flange is at a funny angle so it can fit the TXS 3" system which has a weird 3" intermediate pipe with a double flange, one to fit the TXS 2.5" magnaflow as well as the 3" RFL. I'm not sure if the RFL can fit non-TXS exhaust systems. Just something to check before making the trade.
