Description
REMARK Axle-Back Exhaust for 2015–2021 Subaru WRX/STI (VA). Give the VA WRX/STI a larger quad-tip appearance using the 4-inch axle-back configuration.
The tip size is the visual distinction from the 3.5-inch version; the tubing remains 2.5-inch stainless steel. This rear-section format is useful when you want to retain a compatible factory-layout mid-pipe.
Single-wall tip construction uses one layer at the visible outlet edge. The tip diameter and the working pipe diameter are different measurements, so compare both when choosing the rear appearance. Polished or burnt stainless finishes primarily change presentation; the muffler layout and the remaining exhaust components are more relevant to sound.
