Overview

The Large Bore-HD DPF-Delete race down-pipe back exhaust system eliminates the use of the restrictive diesel particulate filter (DPF) and catalytic converter for maximum performance and extreme mileage gains. This free flowing exhaust system outflows the factory exhaust by 67% and is constructed out of durable 4" mandrel bent 409 stainless steel and uses bayonet style hangers and band clamps for a clean installation. This system comes complete with all tubing, bayonet hangers and band clamps. You will be shocked at the performance and mileage improvement you will see from this system. This system requires the use of a controller with a DPF-delete function. All aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.

Leak-Free Seal:

Aggressive Sound:

Perfect Fit:
OE style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The Bayonet tip holds the hanger bushing in place for an OE style fit that does not change with time.

Flow and Performance:
Large Bore-HD exhaust systems are constructed of mandrel bent 4" stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.
