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.
The resonator is an acoustic-control element within the exhaust path. It should not be confused with a catalytic converter or treated as a guarantee against cabin drone. Evaluate the complete configuration, including rear mufflers and any changes ahead of the cat-back, when selecting the desired sound level.
