Product Description

The Borla 40348 ProXS™ Universal Muffler is crafted to provide a balance of performance and aggressive exhaust tone for custom exhaust builds. Featuring a straight-through core design, this muffler enhances exhaust gas flow while mitigating excessive drone - making it a popular choice for street, performance and custom applications. Its center inlet and dual 2.5" outlets give installers flexibility in routing exhaust tips or adapting systems with single-to-dual configurations.

Built from high-grade T-304 stainless steel with an all-welded construction, the Borla ProXS™ muffler resists corrosion and offers durable service life. The reversible design allows you to orient the inlet and outlets to match your exhaust layout. This universal part is ideal for performance exhaust upgrades, custom fabrication projects or replacing a worn factory muffler when matched to 2.5" exhaust piping. Note that welding or professional installation is required for proper fitment - this part does not use vehicle-specific hangers or bolt-on connections.
