The AAM Competition Premium Sports Variable Volume Nissan GT-R Exhaust is the ultimate exhaust system fro your GT-R. Constructed from superior quality 90mm T304 Stainless Steel, this direct bolt-on exhaust replacement streamliens the turbulent GT-R exhaust flow; maximizing total vehicle power out put.

In addition to the power increase, the sound the exhaust emits is incredible. It here true engineering beauty behind this exhaust shines. The rear section of the exhaust initially runs into a dual outlet muffler, exiting through two dual tipped exhaust outlets out of the factory rear bumper. This exhaust direction however, can be changed remotely by the driver. Installed in the rear section of the exhaust is a valve that can re-direct the flow of the exhaust coming from the engine. It allows the exhaust to exit to a single side through a muffler, effectively causing the exhaust to emit a subtle, almost factory sound, or the exhaust can be opened to run through non-resonated exhaust pipe to create an extremely aggressive race exhaust tone.

Peak power output is unaffected by adjusting the volume of the GT-R exhaust.
