Product Description

The Borla 400500 S-Type Universal Performance Muffler is an engineered exhaust component crafted to improve sound and flow characteristics in custom or aftermarket exhaust systems with 3" piping. Featuring premium T-304 stainless steel construction and Borla's S-Type internal design, this muffler delivers a performance-oriented tone that's rich and aggressive yet controlled, with reduced cabin drone compared to straight-through designs.

Because it's a universal component, installation involves matching the 3" inlet and outlet to your vehicle's existing exhaust tubing. You can weld or clamp it into place depending on your build needs. The mandrel-bent internal geometry ensures smooth respiratory flow, and the brushed stainless finish can be polished or detailed as desired. Backed by Borla's Million-Mile Warranty, the 400500 is a durable choice for custom exhaust builds, race applications, or performance street vehicles where sound quality and performance matter.
