Sound & Performance:

The S-Type sound level provides an enhanced exhaust note that's more aggressive than stock while remaining refined enough for everyday driving. Borla's patented technology increases exhaust velocity, adding power and driving excitement while maintaining fuel economy. When paired with optional mid-section 60738 featuring a merge X-pipe, the system delivers increased volume while preserving the distinctive Borla tone.

Premium Construction:

Every component is crafted from premium T-304 stainless steel, providing exceptional corrosion resistance and long-term durability. The black chrome tips require special care—clean with hot water and a microfiber cloth only. Do not use Borla Stainless Steel Polish 21461 on black chrome finishes.

Backed by Borla's legendary Million-Mile Warranty, this system represents decades of racing heritage and exhaust expertise. Borla stands behind their reputation as the world's most experienced and most winning exhaust brand with unmatched quality assurance.
