Enhance performance and sound with advanced stainless steel technology.
The Borla Cat-Back Exhaust System Kit is designed to replace the factory exhaust system while maintaining emissions compliance. This system is located behind the factory catalytic converter, ensuring that emissions remain untouched. It features patented straight-through and multi-core technology that helps to unleash hidden horsepower, providing a noticeable increase in overall sound level and performance.
Constructed from aircraft-grade T-304 stainless steel, this exhaust system is engineered for durability and resistance to rust and corrosion. The aggressive 'S-Type' sound produced under acceleration enhances the driving experience without introducing drone at highway speeds. The system follows the same exhaust path as the original, utilizing the factory hangars and rubber isolators for a straightforward installation.
With a diameter range of 2-1/2 inch to 2-1/4 inch, this single exhaust system features a dual exit configuration, allowing for a polished and refined look. The included 3 inch round angle-cut exhaust tip further enhances the aesthetic appeal while contributing to the overall performance of the vehicle. This exhaust system is a reliable choice for those looking to improve their vehicle's exhaust flow and sound.
