Description
REMARK Sports Touring Cat-Back Exhaust for 2015–2021 Subaru WRX/STI (VA). Give the VA WRX/STI a dedicated Sports Touring cat-back with a four-tip rear layout.
A 3-inch main pipe transitions to dual 2.5-inch branches and two rear mufflers. The 4-inch outlets emphasize the factory quad-tip arrangement while the mufflers and selected mid-pipe determine the system’s sound-control layout.
Non-resonated identifies the center-pipe configuration, not the absence of every sound-control component. Rear mufflers and the rest of the system still shape the result. Choose this version with cold starts and normal cruising in mind, particularly if the vehicle has other changes that increase exhaust sound.
