Borla S-Type Exhaust Systems

The S-Type II systems use the latest muffler design to eliminate sound frequencies are often associated with resonance or drone. BORLA Cat-Back and Axle-Back exhaust systems feature patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA Sound of Power respected by motoring enthusiasts everywhere. Each system is built from premium, high-quality T-304 austenitic stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer-controlled CNC manufacturing ensures an accurate fit. Best of all, BORLA stands behind every system with a Million-Mile Warranty. Just what you?d expect from the world?s most experienced (and most winning) exhaust brand.

Replacing your factory exhaust system with an aftermarket performance system is a significant investment in money and time. Of course, you can always try saving money and going with a cheaper system, but you may only get an irritating exhaust tone without any real gains in power. The only silver lining with such a system is that it probably won't last, so at least you won't have to put up with it for long. Instead of going that route, just install a premium Borla Cat-Back exhaust system. You'll get the power and sound you want, with quality materials and construction that will make it the last exhaust system you'll ever need to buy for your car.

Borla custom designs each exhaust system for the specific application, 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. The S-Type series muffler is smaller in diameter than the Touring series, with less space between the core and muffler wall, so it contains less sound absorbing composite filament.

The shape and diameter of the exhaust tubing is optimized for volume and exhaust gas velocity. Borla mandrel bends the 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 percentage of their diameter in sharp bends. This system features an "X" pipe, where the pipes behind the catalytic converter include a crossover junction. This junction reduces excessive backpressure created by close firing cylinders on one bank, allowing it to escape to the other side of the system, thereby improving low and mid-range torque.

But improved performance is only part of what you want in an aftermarket exhaust system, because all the horsepower in the world won't matter if it doesn't sound right. There's no need to worry with a Borla System. They have many years of automotive acoustical experience and the company is staffed with automotive enthusiasts just like you that listen and drive cars to make sure your system has the right sound to go with the power. The S-Type system is somewhat louder than the Touring system 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.

Finally, 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 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.

The Borla S-Type Series Stainless Steel Cat-Back 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.
