AAM Competition GT-R 90mm Premium Adjustable Exhaust

The GTR’s factory exhaust system is a great design. With no mufflers (only two small resonators) Nissan did their homework to optimize the exhaust system design at the factory 480hp level (410-420awhp). However, as with most exhaust systems, the GT-R’s exhaust can be significantly improved. What is the leading problem with the GT-R’s factory exhaust when it comes to power? It is simply not big enough – factory piping diameter is too small.

This system is adjustable from the driver’s seat via a switch that allows you to change between a quiet, conservative street exhaust note, to a much louder, more aggressive race exhaust note on the fly. You also have the option to tailor the exhaust note anywhere in between the two extremes to find the sound that best suits your driving style.
