Borla XR-1® 2.5" Cat Back Exhaust System


BORLA’s XR-1® Raceline products are the choice of today’s hottest drag and oval track racers. Featuring a patented uninterrupted-flow design and multi-core technology, BORLA’s XR-1® mufflers actually outflow a straight piece of pipe in repeated testing. XR-1® race products are made in the USA and constructed of aircraft-quality T-304 stainless steel for track tough durability.

These attributes, coupled with an aggressive sound of power and awesome big tip, proclaim this Shelby GT500 is all business. Airflow management and exhaust engineering is a science with which BORLA has more experience than anyone in the exhaust aftermarket. The performance matches the famous BORLA systems of the past but with a unique muffler and exhaust configuration canceling additional high frequency sound waves. Delivering a significant increase in CFM from the factory system which, as most engine builders will confirm, accounts for the dramatic power improvements. Perhaps more importantly, this added flow maximizes performance for other aftermarket enhancements installed on the Mustang because all BORLA exhaust products are tuned for maximum output from any aftermarket performance upgrade.

BORLA, the original pioneers of aerospace-grade T-304 stainless steel (superior to 409 or aluminized steel) free-flow exhaust utilizes patented award and race winning technology to deliver quality, sound, performance gains and enhanced fuel economy – all with an easy bolt-on installation. Unsurpassed written Million-Mile Warranty.
