Borla engineered the S-Type Stainless Steel Round 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 muffler, also being a part of Borla exhaust, provides an aggressive throaty sound thanks to the design that absorbs the sound waves without disturbing the power waves, unlike 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 S-Type series muffler is smaller in diameter than most factory mufflers, with less space between the core and muffler wall, so it contains less sound absorbing composite filament. As a result, it’s definitely louder than a factory muffler, with a throaty, aggressive note during acceleration. It’s for someone that wants their vehicle to have the real sound of performance, but without an annoying drone or resonance through the cabin.
Borla uses austenitic stainless steel in the construction of the S-Type series 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 a stainless steel perforated tube 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.
