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.
Titanium at the rear canister does not make the whole exhaust titanium. The center-pipe construction remains a separate specification. This distinction matters when comparing cost and installed mass with a full titanium system. A burnt-looking tip should likewise be identified by its material rather than its color alone.
