R35 GT-R Amuse R1000 No. 2 90mm GT-RR Race Version, No Cat, Titanium
Powerhouse Amuse Japan has developed special exhaust components using GT-RR's collaborative specifications for worldwide market sales.
The new exhaust components are known as "R1000 GT-RR SPL STTI" and is produced by Amuse in Japan using their proprietary STTI (super tough titanium/Ti) material. This Y pipe which was developed in collaboration between GT-RR.COM and Amuse takes the successful design of Amuse's prior R1000 No. 2 Y Pipes and increases the size 10mm larger to maximize power in higher boost GT-R applications. As a result this new racing system has twin 80mm pipes transitioning into 90mm.
Each order is painstakingly produced by hand in Japan using nothing but 100% titanium. The usual details that Amuse are world famous for can be seen here; including: hollow titanium hangers, superbly controlled heat-treating, and not only exterior polished welds, but deburred and polished interior welds for reduced turbulence.
Note - We have tested this system and found surprisingly no drone. Our car is using this pipe along with the 90mm Amuse x GT-RR rear section. The result is an aggressive sound from outside the car but one that is easy to use for daily driving (as our demo car is daily driven).
This will fit with other exhausts as well.
