Borla XR-1 Racing Sportsman 3.5in. Outlet / 3.5in Inlet Oval Muffler

What you're getting here is Borla's XR-1 Racing Sportsman oval muffler, part number 40945. This is a universal muffler, meaning it's not made for one specific vehicle, but it's designed to fit a wide range of applications where you need a compact, high-flowing exhaust component. It features a 3.5-inch inlet and a 3.5-inch outlet, both centered on the muffler body, and the oval body itself measures 4.25 inches by 7.88 inches, with a 12-inch long body for an overall length of 17 inches.

Borla builds these using high-quality austenitic stainless steel, which means it's going to resist rust and corrosion, even in tough conditions. The patented XR-1 Raceline technology is race-winning stuff, designed for maximum flow and minimal weight, making it a popular choice for racing applications where every bit of performance counts. Inside, it uses a high-temperature continuous-filament fiber acoustic material to help manage sound without choking off exhaust flow. The construction is 100% welded for solid strength, and the natural mill finish can be brushed or polished before installation if you want to dress it up.

Because this is a universal part, you'll want to check for potential fitment issues like transmission or frame rail interference, especially if you're considering the offset inlet/outlet version, though this specific model is center inlet/center outlet. The reversible design offers flexibility during installation, and it's known for offering a good balance of sound and power for performance builds.
