Product Overview

Upgrade the sound, appearance, and driving experience of your Subaru WRX with this Boso Style Muffler Delete Axle-Back Exhaust System, engineered specifically for 2022–present Subaru WRX models equipped with the factory OEM exhaust system. Designed for enthusiasts seeking a more aggressive exhaust tone without the complexity of full exhaust replacement, this axle-back setup delivers instant results with a clean, bolt-on installation.

Constructed from premium T-304 stainless steel, this axle-back exhaust offers excellent corrosion resistance, heat durability, and long-term reliability under daily driving and spirited performance conditions. The dual muffler delete design removes restrictive factory mufflers, allowing exhaust gases to flow more freely while producing a sharper, deeper exhaust note that enhances throttle response and overall driving engagement.

Visually, the system features quad 3.5-inch burnt blue exhaust tips, finished in anodized silver with heat-treated blue accents. The angled round-cut tips sit perfectly within the factory rear bumper cutouts, giving the WRX a bold, performance-oriented rear profile that complements its aggressive body styling.

This exhaust is designed as a direct replacement axle-back system, meaning no cutting, welding, or fabrication is required. It bolts directly to the OEM mid-pipe using the included gaskets and hardware, making it an ideal upgrade for WRX owners who want improved sound and aesthetics while retaining factory fitment and drivability.
Note: This system is intended for use with the stock factory exhaust only and is not compatible with aftermarket exhaust systems.
