Product Details


Uncompromised quality and precision manufacturing is what you get in every Borla ProXS Muffler. Borla manufactures a Pro XS Muffler that will fit almost all vehicles. With a choice of pipe diameters, offsets and single or duel outlet designs, you simply need to pick the one that best suits your vehicle. Your ears will certainly enjoy Borla’s signature deep and mellow sound. This writer purchased a Borla exhaust for his truck way back in the 1990s and now that truck with the same Borla exhaust has been driven over 500,000 miles with no trouble at all. The Borla exhaust still looks great and sounds fantastic after many years and many miles of use. A Borla muffler does cost a little more than most of the competitor’s mufflers but for that extra investment you get Borla’s signature sound and peace-of-mind knowing that you purchased a quality muffler that will outlive most other muffler brands as well as Borla’s Million Mile Warranty to back you up. Alex Borla’s well-engineered exhausts have exceeded the expectations of car, truck and off-road buffs as well as the professional motorsports community since 1978. Mr. Borla started his company with one single purpose, to engineer the best exhaust systems on the market. Borla’s state-of-the-art manufacturing facility in Tennessee uses high tech computer based CNC manufacturing tooling and equipment and employs America’s finest metal workers. Borla goes the extra distance to provide you with the highest quality, best fitting and nicest sounding exhaust for your driving enjoyment.
