The T1R 90R Cat-Back Exhaust is the first 90mm exhaust available for the Evo X. The 90R is intended for cars with substantial upgrades and tuning. For example, cars with all bolt-ons, turbo upgrades, engine internal upgrades, high boost, and agressive tuning. It is also ideal for track use.

The T1R 90R features 3.5" (90mm) piping throughout the exhaust with no bottlenecks. It opens immediately from 3" to 3.5" at the cat/test pipe flange. The 90R will provide the necessary exhaust flow for even the biggest of turbo upgrades for the Evo X.

The T1R 90R is made from SUS304 stainless steel and features a 4" (102mm) stainless steel muffler tip that has been chemically burnt to a blue color. The entire exhaust weighs 24.6lbs (11.2kg). The 90R can be used with the stock catalytic converter, or the T1R Test Pipe. The T1R 90R has the advantage of allowing you to use whichever brand combination of O2 Housing-Down Pipe and Test Pipe with the 90R you prefer.
