Description: Grimmspeed Gentleman's Catback Exhaust

Fitment: 22+ Subaru WRX VB

Details:

Refined Sound. Proven Performance.

The GrimmSpeed Gentleman's Catback Exhaust for the 2022+ Subaru WRX was developed to deliver the sound, fitment, and quality Subaru owners expect from a premium exhaust system. Based on our proven Catback V2 design, this system provides a deep, sporty exhaust note without introducing excessive drone or unwanted noise during daily driving. The result is an exhaust that feels right at home on a stock vehicle while still supporting future performance modifications.

At the core of the system are GrimmSpeed's custom twin-tube mufflers featuring larger perforated cores and a revised internal Y-splitter design for improved flow over previous generations. Combined with a carefully selected long-life packing material, these mufflers were engineered to maintain their sound characteristics over years of use, avoiding the deterioration and increased drone commonly found in lower-quality exhaust systems.

The resonated mid-pipe helps preserve the refined character that has become synonymous with the GrimmSpeed Gentleman's Exhaust. It controls unwanted frequencies while allowing the FA24's natural tone to shine through, making it an excellent choice for drivers planning additional exhaust or turbocharger modifications in the future. A stainless steel braided flex section allows compatibility with a wide variety of exhaust configurations, while double-overlapping stainless steel sleeve clamps and included adjustable polyurethane hangers provide exceptional fitment flexibility and sealing performance.

Constructed entirely from TIG welded 304 stainless steel and finished with quad 3.5-inch tips, the GrimmSpeed Gentleman's Catback Exhaust delivers premium materials, refined sound, and the adjustability needed to achieve perfect fitment on every installation.
