Powerhouse Amuse Japan has developed a special exhaust using GT-RR’s collaborative specifications for worldwide market sales. The new exhaust is known as the “R1000 GT-RR SPL STTI” and is produced by Amuse in Japan using their proprietary STTI (super tough titanium/Ti) material. The exhaust which was developed in collaboration between GT-RR.COM and Amuse takes the successful design of Amuse’s prior R1 Titan Extra STTI model and increases the size from 80mm to 90mm to maximize power in higher boost GT-R applications. Additionally, after considering GT-RR’s research, adjustments to sound tuning were made and the result is a more prominent supercar appropriate tone.

The design utilizes Amuse’s highly effective twin horizontal resonators for sound control but does not use any other resonators on the piping. As a result of the new design, the R1000 GT-RR SPL STTI exhaust yielded surprising results during Amuse Japan’s dyno test. After repeated testing, the new special exhaust has produced 21 horsepower more than the previous Amuse exhaust system on the very same GT-R.
