The new exhaust components are known as "R1000 GT-RR SPL STTI" and are produced by Amuse in Japan using their proprietary STTI material.

We have tested this system and found surprisingly no drone. Our demo car is using this pipe along with the 90mm Amuse x GT-RR rear section with a aggressive sound underloud however it is easy to use for daily driving. This piece fits with othe rexhaust systems as well. At an additional cost, this system may be customized with resonators and high flow cats.
