There’s probably no passenger vehicle on the road that's as demanding on parts as a Diesel Pickup Truck, so why waste time with poorly performing equipment that won't last. When you want maximum performance and quality, with the peace of mind of a million mile warranty, there's no other exhaust system but Borla.

The heart of the Borla system is their patented straight-through, multi-core, XR-1 muffler. This muffler is proven on the racetrack and so good it’s used by competitors in racing events where mufflers aren’t even required! Borla uses this muffler in their diesel systems for the most possible airflow and to lower exhaust gas temperatures. The increased airflow results in the most performance gains while the lower exhaust gas temperatures improve engine durability.

The patented straight through, multi-core muffler design reduces restriction and increases exhaust gas velocity, making sure each cylinder is completely evacuated to make room for the incoming charge. This design absorbs the sound waves without disturbing the power waves, in contrast to the chambered mufflers used by most aftermarket companies. Chambered mufflers use partitions or baffles to subdue sound waves, which also creates backpressure and reduces power.

The shape and diameter of the exhaust tubing is optimized for volume and exhaust gas velocity. Borla mandrel bends the 4" stainless steel tubing for smooth bends and to make sure the pipe maintains its size and shape throughout the entire length. Tubes that aren’t mandrel bent can lose a significant percentage of their diameter in sharp bends.

The combination of XR-1 muffler and 4" diameter pipes deliver the renowned Borla sound of power, a deep, throaty growl, through a massive 5" angle-cut stainless steel polished tip.

However, the best power and sound is meaningless if the exhaust system rots away in a few years. Borla uses the finest materials and construction techniques to make sure this won’t happen. They use austenitic stainless steel for their systems, which contains high levels of nickel and chromium, to resist corrosion. This material is harder than the lower grade stainless steel used by the OEM manufacturers, yet is very ductile. Nevertheless, the increased hardness requires special equipment to form and bend. The muffler contains stainless steel perforated tubes wrapped with several layers of stainless steel sound absorbing material and a layer of ceramic sound absorbing, high temperature material, all contained in a fully welded stainless steel shell.

The Borla Stainless Steel Cat-Back Diesel Exhaust System comes complete with everything required for installation, including detailed instructions. Borla is so confident in the quality of this system that it’s guaranteed against defects in materials and workmanship for one million miles.

Borla® is the leading manufacturer of stainless steel performance exhaust products.
