Power House Amuse R1000 90mm Race Spec STTI Mid Pipe for GT-R

July 31, 2010

When Power House Amuse launched their massive 90mm titanium exhaust system recently it got a lot of us thinking about just how best to move exhaust gas through this massive system with a relatively puny looking 80mm mid pipe. Little did we know they had this card up their sleeve the whole time.

The new exhaust components are known as “R1000 GT-RR SPL STTI” and are 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.

According to the guys at GT-RR who have fitted up the first one to their own car, the Amuse 90mm mid pipe offers a aggresive exhaust note without any noticeable drone inside. While the race version shown here does not come with any catalytic converters, these may be optioned and you should contact the guys at GT-RR for more info there…
