Description
REMARK R1-Spec Cat-Back Exhaust for 2022+ Subaru WRX (VB). Use a single R1-Spec rear canister with a stainless steel mid-pipe on the WRX.
The mid-pipe remains stainless steel even on the titanium-muffler version. This is an important distinction from the full titanium system, and it lets the rear canister material be selected separately from the main pipe construction.
Compare the complete layout rather than the visible tips alone. Pipe diameter, rear mufflers, resonators, and any valve arrangement serve different purposes. A larger or differently finished outlet does not establish a measured power gain or a particular cabin sound level; choose the configuration that matches the intended vehicle use.
