Description

The Invidia R400 Gemini cat-back fills the sound gap between the mild Q300 and the aggressive N1 - a deep, pronounced exhaust note throughout the RPM range with no harsh cabin noise at highway speeds. Quad 4-inch slash-cut polished stainless steel tips give the rear a race-ready look, while 3-inch mandrel-bent 304 stainless steel piping delivers dyno-proven gains of +17 horsepower and +26 lb-ft of torque.
