You may be asking yourself if Borla is worth the cost. Well to ease your mind we are here to tell you that every Borla Cat-Back System, Borla Header and Rear Section Exhaust is constructed of aircraft-quality authenticate stainless steel and is stainless inside and out and utilizes T-304 stainless steel because it is the most resistant to corrosion culminating in a long-lasting and resilient exhaust system.

The Borla exhaust system & Borla Muffler are less restrictive and preserve the velocity and high frequency so the dominant sound is behind the tailpipe where it belongs. And if you are looking for loud then the ATAK system will give you the highest decibel levels. And Borla’s patented, less restrictive design means greater horsepower and gas savings.

The Borla exhausts are specially designed from scratch for each individual vehicle and great care is taken to create the perfect muffler body shape. Coupled with precision internal core configuration, flow dynamics and sound you are assured of an exhaust that is special in every way. .
