Premium Diesel Exhaust. The AFE ATLAS 5-Inch DPF-Back Single Exhaust System with Side Exit is engineered to enhance diesel truck performance by optimizing exhaust flow while maintaining OEM fitment.

High-quality OE-style bayonet hangers and flange clamps assure a secure, professional fit that preserves factory mounting points for a clean and durable finish.
