The TurboXS WRX STI Standard Rear Muffler Assembly is the epitome of subdued looks but performance sound. It's a full 3 inch straight through design so this muffler can support well over 500whp while still offering a "low key" look and sound for the typical street 300-400whp enthusiast. To compliment your rear bumper fascia, the muffler features a 3.5 inch double walled tip that looks phenomenal.

You can fit this rear muffler section to either a stock midpipe if you just want a noise and small performance increase or you can connect it to one of our midpipe to make a full 3" catback exhaust system.

NOTE: This part is designed to work with either an OEM midpipe OR a TurboXS midpipe only!
