The AAM Competition GT-R 4" Premium Adjustable Exhaust System was designed specifically for those seeking the highest possible exhaust flow, while having the ability to adjust exhaust tone and volume at the touch of a button. Using aircraft grade T-304 stainless steel, each exhaust is hand-welded at AAM Competition's facility in the USA, and includes a 4" Midpipe. With proven support on GT-Rs making 1,400+ Wheel Horsepower, the AAM Competition GT-R 4" Premium Adjustable Exhaust System is a must-have for anyone chasing BIG power with total control over sound.
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.
