The aFe Large Bore-HD DPF-Back Exhaust fits the 2020-2026 Chevy Silverado 3500HD 6.6L L5P Duramax and delivers a 4in mandrel-bent 409 stainless flow path for stronger throttle response and increased exhaust velocity.
Product Overview
This DPF-back system replaces the factory exhaust from the DPF rearward with 4in mandrel-bent 409 stainless steel tubing. A mitered merge collector reduces turbulence to boost horsepower, torque, and throttle response on the L5P Duramax.
Dual 5in black 304 stainless intercooled clamp-on tips finish the system with an aFe POWER logo plate. Factory-style hangers bolt to OEM mounting locations for a direct fit.
