Borla XR-1 Racing Sportsman 3.5in. Outlet / 3.5in Inlet Oval Muffler - 5in Diameter x 15in Length

Borla is well-known for their performance exhaust systems, often found on race cars and enthusiast vehicles. This XR-1 Racing Sportsman muffler is a prime example of their race-winning technology, designed to give you a competitive edge. It's built with high-quality T-304 austenitic stainless steel, meaning it's built to last and won't rust, even in tough conditions. The patented, flow-through design is the heart of this muffler, helping to improve exhaust flow and performance without sacrificing too much sound control, thanks to its continuous-filament fiber acoustic material.

This oval muffler is Borla's number one selling racing muffler, and for good reason. It's designed to be lightweight and compact, making it a great fit for applications where space is tight, like many door car or roadster builds. The reversible design offers flexibility during installation, and the 100% welded construction ensures it's solid. While it has a natural mill finish that can be customized, its primary goal is to provide a free-flow design that balances power gains with a more controlled driver compartment sound, a feature appreciated even by record-holders.
