Construction & Design

The Borla Cat-Back Exhaust System is crafted from high-grade T-304 stainless steel, known for its exceptional corrosion resistance and strength. This premium material ensures the system withstands harsh environmental conditions while maintaining its appearance and performance over time, outperforming lesser 409 stainless steel alternatives.
