I have an SPT(bosal) 3" stainless pipe that goes into a STi performance muffler for the WRX. The muffler is only 2 1/2" though. Has great sound and in good shape. Mid pipe is brand new, never seen exhaust flow. No gaskets included. I want $325...the SPT system is $400 new, and the STi muffler is $525 by itself.
