This new Sports Muffler is manufactured from corrosive-resistant stainless steel to ensure light weight, and is specially designed for all WRX STI sedan models (GV). The entire muffler is buffed to a glossy finish. The 95 mm diameter double-walled tail pipe, featuring slash cut construction and a stamped STI logo, extends to the back edge of the rear bumper to give the rear of the car a high-quality look. The muffler is tuned by STI with a safe and reliable structure that will not affect the power unit or exhaust system. In addition, the muffler sound was tuned meticulously by the development team to a sporty, high-quality, and reassuring sound that fits the character of the WRX STI.
Compliant with safety standards. Type 1 after-market muffler performance test complete.
