(S-Type Exhaust) (Quad Polished Rolled Tips)
 

Systems labeled "Rear Section Only" are simply axle-back exhausts; they are not full cat-back exhaust systems. Each Borla exhaust system is separated by the overall loudness of its tone:
  • Touring Type is mild.
  • S-Type is noticeable.
  • ATAK Type is very aggressive.

An exhaust system is one of the first things to upgrade and among one of the first noticeable modifications for a car. A rich exhaust note adds so much more to the personality of the car, and echoes the performance of the engine too. While most systems go for bigger and louder, Borla has a slightly different approach. Borla is meticulous with their exhausts, and they take great care in having a truly well balanced system in terms of sound and performance.

Larger does not always mean better when it comes to exhausts. Having a system that allows the maximum amount of flow, while also retaining proper thermal dynamics, ensures maximum performance across the board. Borla takes their time to select the best diameter piping, muffler, and even material to ensure this. All systems are mandrel bent, hand welded, and made of aircraft-quality authentic T304 stainless steel. This process ensures a quality exhaust that not only will last a very long time and look great, but will retain heat properly for maximum performance. Each system has the sound carefully crafted to suit it as well. Borla exhausts have a very distinct and noticeable, deep, throaty tone that is sure to put a smile on your face.

Key Features:
  • Excellent flow characteristics.
  • Carefully selected pipe diameter for best overall performance.
  • Super lightweight and strong T304 stainless steel.
  • Full cat-back and axleback (rear section) exhaust system options.
  • Amazing looks and sound.
  • Bolt-on design for a simple install.
  • Carries Borla's million mile warranty!
