Features:

  • Increased exhaust flow for better performance
  • Definite performance tone at cruise with a throaty, aggressive sound during acceleration
  • Patented straight-through muffler design reduces backpressure while absorbing sound waves
  • Made from the finest austenitic stainless steel for long-lasting durability
  • All welded construction
  • Backed by the exclusive Borla Million-Mile warranty
  • Proudly made in the USA

Borla engineered the Transverse Flow Stainless Steel Oval Muffler to make the most horsepower and torque with the best sound quality. The patented straight through 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.

Borla - Pro-XS Transverse Flow Mufflers

The Transverse Flow muffler is for someone that wants their vehicle to have the real sound of performance, with a throaty, aggressive note during acceleration, but without an annoying drone or resonance through the cabin.

Borla uses austenitic stainless steel in the construction of the Transverse Flow muffler, 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.

Borla is so confident in the quality of this muffler 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. The company began three decades ago making exhaust systems for concours classic Rolls Royce and Ferrari models, and gradually evolved to become the premier manufacturer of performance exhaust products for street, off-road and racing. Borla pioneered many improvements in the design of performance exhaust systems, holds several patents for innovative exhaust system technology, and has won numerous “Best New Product” awards. Today the company operates a state of the art research and development center in Oxnard, California, and makes all of its products at a world-class manufacturing facility in Johnson City, Tennessee.
