The S-Type Exhaust System by Borla features a straight through muffler design. This helps reduce 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 power waves. This is a huge difference compared to most aftermarket companies that use chambered mufflers. Chambered mufflers use partitions or baffles to subdue sound waves which can create backpressure and reduce your vehicles power.

The S-Type series muffler is smaller in diameter than the Touring series. With less space between the core and muffler wall, it contains less sound absorbing composite filament. The shape and diameter of the exhaust tubing is optimized for volume and exhaust gas velocity. Borla S-Type exhaust features mandrel bent stainless-steel tubing. This means it smooth bends and the pipe maintains its size and shape throughout the entire length. In comparison, tubes that aren’t mandrel bent can lose a percentage of their diameter in their sharp bends.

Borla S-Type Exhaust Sound

Let’s talk sound! The S-Type System is somewhat louder than the touring system. It features an aggressive, throaty note during acceleration. While cruising you can expect a definite performance tone. If you’re looking to have a real performance sound without annoying drone or resonance throughout your cockpit, the S-Type Exhaust is a must have.

The muffler contains a stainless-steel perforated tube wrapped with several layers of stainless-steel sound absorbing material. Furthermore, it features a layer of ceramic sound absorbing, high temperature material, all contained in a fully welded stainless steel shell.
