Borla Performance Industries hits another home run with a tuned "true" dual Cat-Back™ exhaust system (140176) for the hot new Ford Mustang V6 (4.0L). Incorporating unique, genuine BORLA race-bred straight-through free-flowing mufflers that create superb power increases while exuding that incredible, bold BORLA signature sound. Testing has shown average power increases of 18 horsepower and 14 ft/lbs of torque with almost an identical weight to the factory single exhaust.

BORLA utilizes its racing experience to rev up this hot six shooter with an exhaust that resembles the magnum loads in a handgun. Hot and Powerful: letting this fun pony kick up its heels like its Big Brother V8 without the big insurance premium. The magic begins with a Cat-Back™ that slips on directly behind the cats with BORLA high-end, race-proven stainless steel clamps (no welding required). The BORLA system then merges into a high flowing BORLA X-Pipe that exits with large 4” round rolled edge and angle-cut mirror polished BORLA embossed tips. Customer or installer will be required to cut the rear fascia to accommodate the extra tip, but BORLA’s engineering department provides a simple template to make this a simple operation. In the end, you have the V8 look and sound combined with excellent power gains and the genuine BORLA trademark trusted by more winners in professional auto racing than any other brand.

BORLA has a 30-year tradition of building performance exhausts for high end performance machines and is the original pioneer of high quality, austenitic stainless steel (superior to 409 or aluminized steel) free-flow, CNC mandrel bent exhaust. Patented award and race winning technology delivers quality, sound, performance gains and enhanced fuel economy --all with an easy bolt-on installation and backed by an unsurpassed written million-mile warranty.
