The PERRIN Dual Single Tip Axle Back Exhaust is a bolt-on performance upgrade engineered specifically for the 2022–2026 Subaru WRX. Built entirely from 304 stainless steel with TIG-welded construction, it replaces your stock axle-back section to deliver a more aggressive exhaust note without requiring a full cat-back swap. Whether you're daily driving or pushing the WRX hard on a back road, this system is designed to enhance both sound and appearance.
Key Features & Benefits
- 304 Stainless Steel Construction – Full stainless steel build resists corrosion and holds up to heat cycling over years of use, maintaining appearance and structural integrity long-term.
- Brushed Stainless Steel Finish – The brushed finish gives the tips and piping a clean, premium look that stays presentable even after extended use.
- Dual Oversized 4.5" Slash-Cut Tips – Aggressive-looking slash-cut exhaust tips add a visual upgrade to the rear valance while complementing the enhanced exhaust tone.
- TIG Welding Throughout – Precision TIG welds ensure leak-free joints and consistent flow, resulting in a cleaner, more durable finished product than MIG-welded alternatives.
- RPM-Responsive Sound Profile – The system is tuned to produce a mellow, controlled rumble at low RPMs and light throttle, transitioning to a more aggressive tone under hard acceleration — no drone, all character.
- OEM Midpipe Compatible – Designed to mate directly with the factory midpipe and most direct-fit aftermarket midpipes, making installation straightforward with no cutting or fabrication required.
- 5-Year Manufacturer Warranty – PERRIN backs this system with a 5-year warranty, reflecting confidence in the materials and manufacturing quality.
