Borla Mach I Cat-Back Exhaust System S-Type for 1999-2004 Ford Mustang

For over 4 decades, BORLA® Exhaust has been the choice of Mustang experts, from the Cobra-R SVT Mustang to the Ford GT. Major players in the racing industry and leading tuners from Roush, Steeda, Saleen and Ford Racing to the Shelby 427 Cobra have relied on BORLA®. BORLA®'S experience and advance engineering produced the classic S- Type exhaust with outstanding flow numbers that generates great power enhancements with no drone inside the vehicle. These attributes, coupled with an aggressive sound of power and single 4" round bright chrome on T-304 stainless steel tips on each tail pipe, proclaim this 2.5" diameter Cat-Back™ system 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 addi tional high frequency sound waves delivering a significant increase in exhaust flow 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 enhancement s 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 winnin g technology to deliver quality, sound, performance gains and enhanced fuel economy – all with an easy bolt-on installation. Best of all, each system comes with the BORLA® Million-Mile Warranty.
