Borla ProXS Muffler (40358) offers a versatile, high-performance solution for universal applications, featuring a 2.5-inch inlet and outlet for broad compatibility. Designed for flexibility, its reversible configuration allows for multiple installation options, while the high-quality T-304 austenitic stainless steel construction ensures lasting durability and resistance to rust. Built with 100% welded seams and engineered for performance, this muffler delivers both strength and enhanced exhaust flow.
The Free Flow design improves power output by reducing backpressure, and the integrated high-temperature continuous-filament fiber (CFF) acoustic material helps control sound without compromising performance. Its natural mill finish can be left as-is or customized with a brushed or polished look to suit your vehicle’s style.
