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 aggressive ATAK® exhaust with outstanding flow numbers that generates great power enhancements. 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" Cat-Back™ system is all business.

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.
