# Borla 05-09 Mustang GT 4.6L V8 SS Aggressive Exhaust (rear section only)

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®. This awesome 2.5" diameter BORLA® Axle-Back system bolts on, is lighter than the factory system, includes our famous S-Type mufflers with outstanding flow numbers that generate great power enhancements. The system delivers the great sound BORLA® with no drone inside the vehicle, and features a single 4" round bright chrome on T-304 stainless steel tip on each muffler assembly. These attributes, coupled with an aggressive sound of power and awesome big tips, proclaim this Stang 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 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 enhancements installed on the Mustang because all BORLA® exhaust products are tuned for maximum output from any aftermarket performance upgrade.
