Borla Pro-XS Universal Muffler 2.25" Offset Inlet / 2.25" Center Outlet (40658)
Enhance your custom exhaust system and maximize horsepower with the Borla Pro-XS Universal Muffler. Engineered as the perfect upgrading solution for sport compacts, custom cars, and street builds utilizing 2.25-inch piping, this compact oval muffler features Borla's street-legal, straight-through free-flow internal layout. By eliminating restrictive backpressure, it optimizes exhaust gas velocity to improve horsepower and torque delivery. It unleashes a deep, sporty exhaust note under acceleration while maintaining excellent sound control at cruising speeds via premium continuous-filament fiber acoustic packing material.
Built to easily outlast stock equipment, this heavy-duty street muffler features a 100% welded assembly crafted from high-quality T-304 austenitic stainless steel for superior resistance to rust and weather elements. The smooth, un-notched necks are specifically designed for a seamless weld-in installation by custom fabricators, though they can also be secured using heavy-duty wide two-bolt style band clamps. Its smart, fully reversible configuration allows for complete packaging flexibility under your vehicle, making it an excellent choice for tight chassis spaces. Arriving in a classic natural mill look that can be brushed or polished to perfection, this American-made unit is backed by Borla's legendary Million-Mile Warranty.
