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 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 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.175.99Brand: Borla Part Number: 40842S UPC: 808422408424

Had this muffler professionally installed. First words, wow! Sounds amazing. Not a cheap sounding muffler, gives a rich deep low growl. It's everything I expected it to be. Would recommend this product to anyone looking to upgrade/enhance your car's exhaust and performance.Was this review helpful for you?

This product just simply looks and sounds amazing. I bought this product simply for the sound. The muffler gives ur car that amazing deep street car sound. It sounded better than on the website. Little did I know to that it would actually improve my gas mileage as well! I couldnt be happier I paid $51 for professional installation and its perfect. I would highly recommend this product to anyone who wants to improve their fuel mileage and have that great sound. Also make sure ur silencer is off ur car as well cuz I replaced my muffler tip with this one but it wont be loud unless u get the silencer removed as well so u will get all the exhaust and power and sound out of this muffler. Definitely going to buy another one of these for my 2nd muffler I have under my car to make it more powerful!Was this review helpful for you?

I purchased the Borla S-type muffler and thought it was gonna be like any other aftermarket muffler I have had before, but it was extremely different! This muffler increased my horsepower, torque, and fuel mileage on my 1998 Z-24 Chevy Cavalier with the twin cam 5- speed. The muffler did give it an amazing deep throaty sound. Plus, I made it 21/2 inch exhaust. Ha-ha! It's awesome.5 people found this review helpful.Was this review helpful for you? YesNoShare this review:
