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 your stock midpipe if you just want a noise and small performance increase. Ideally this should be installed with our WS02-SBE Stealthback to make a full Turboback or it can replace the WS02-RMA-TI Titanium Tip Rear Muffler Assembly (N1 Style) for a more mature look without any loss in power.
