Product Description

The Remark RO-TSVB-S4 Axle-Back Exhaust is a direct bolt-on muffler delete system engineered specifically for the 2022 through 2024 Subaru WRX (VB chassis), all-wheel drive. With mandrel-bent 2.5" T304 stainless steel piping and polished 4" single-wall slanted tips, this axle-back replaces the heavy factory muffler section with a high-flow straight-through design that improves exhaust sound presence and reduces rear-end weight. Designed to fit seamlessly using OEM hanger rods and included gaskets/hardware, this system is simple to install with basic tools.

The large 4" tips fill the WRX rear bumper cutouts for a more aggressive visual appearance while producing a deeper, more assertive exhaust tone. Ideal for enthusiasts seeking a cost-effective upgrade without committing to a full cat-back system, the RO-TSVB-S4 enhances driving experience with improved sound and premium stainless construction. This axle-back exhaust is designed to bolt onto the factory midpipe and may require compatible connections when used with non-OEM systems.
