Installing an Invidia exhaust is a great way to improve horsepower, performance, weight reduction, and exhaust sound. Made from T304 Stainless Steel, this exhaust reduces weight while giving you additional strength to reduce the potential for cracks and breaks along with rasp and vibration. Optimized flow for minimal back pressure for performance gains. You'll get a great sound and tone from this cat-back exhaust.

The R400 mufflers offer a rich, deep, aggressive exhaust note which enhances the natural tone of your car's engine without introducing any unwanted sound qualities or excessive volume. Specifically designed to fill the sound gap between the Q300 and N1 system, the R400 produces a unique, agressive note while minimising harsh cabin noise (particularly at highway speeds). The R400 muffler was designed using years of experience from Invidia's engineers to allow the perfect balance between unrestricted exhaust gas flow and sound dampening. This exhaust system will provides a pronounced exhaust note throughout the entire RPM band even when only installed as a cat-back system. The R400 muffler design also looks great with a race inspired design that will turn heads.
