Borla Pro-XS Universal Muffler 3" Center Inlet / Dual 2.25" Outlet (40670)
Enhance your custom exhaust system and maximize horsepower with the Borla Pro-XS Universal Muffler. Engineered as an excellent upgrading solution for full-size trucks, SUVs, and custom split-rear street builds, this premium oval muffler features an extended 19-inch body for enhanced sound dampening. Its street-legal, straight-through free-flow internal layout completely eliminates restrictive backpressure, optimizing 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 configuration is optimized for single-to-dual setups with a 3-inch center inlet and dual 2.25-inch outlets, though its fully reversible architecture also allows it to run in reverse as a dual-to-single collector. 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. 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.
