    Under Pressure...
    Millions of exhaust systems are replaced every year due to corrosion and poor performance. Automotive exhaust gas attacks the system from the inside while vibration, chemicals, road salt, and other harsh conditions attack from the outside. When you think about all the stress your exhaust system goes through, it's easy to see why you need a Borla stainless steel system!

    Built to Last...
    Borla builds their exhaust systems from 100% T-304 aircraft-quality stainless steel (not mild steel, aluminum, or coated aluminum). While coating substandard materials like mild steel may prolong life, these coatings suffer and typically fail at the weld points. Stainless steel maintains form and function at all points for superior corrosion protection. As Borla employees say, ''When you compare coated materials to 100% T-304 stainless steel, it's like comparing gold-plated metal to solid gold!''

    Worth Its Weight in Gold...
    Borla's world-class build quality and performance gains are considered by many to be an outstanding investment. And Borla's One Million Mile Warranty is proof that they take their products very seriously.

    Available in Cat-Back and Rear Section Kits...
    Cat-Back System- Comes with the necessary muffler inlet pipes, mufflers, tail pipes and exhaust tips.
    Rear Section- Comes with mufflers, exhaust tips and necessary mounting hardware.

  • S-Type Mufflers - Straight Through Power, delivers the intoxicating, aggressive, Borla's “Sound of Power”.
