Description
Upgrade or replace the rear exhaust/muffler on your early Porsche 911 with this stainless steel GT3-style sport exhaust. This rear muffler features twin center 63mm tail pipes for a clean performance look and a more aggressive sport exhaust appearance.
Made from stainless steel, this sport exhaust offers improved corrosion resistance compared with standard mild steel exhaust components. The GT3-style twin center outlet design is a popular choice for custom, performance, and sport-style Porsche 911 exhaust builds.
Important Fitment Note: This exhaust is for select Porsche 911 2.0L-2.4L applications. Always confirm engine type, exhaust layout, inlet flange style, rear valance/tail pipe clearance, and bumper compatibility before ordering. Some installations may require rear valance modification for center-exit tail pipes.
