Large Bore-HD 4" 409 Stainless Steel DPF-Back Exhaust System

Flow and Performance:
This Large Bore-HD exhaust system is 100% hand MIG-welded and Constructed from 4" mandrel-bent stainless steel tubing for maximum flow. The smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's. A mitered merge collector is also incorporated to eliminate dead space that can cause turbulence and hinder flow.

Intercooling tailpipe:
This system is designed with Intercooling tailpipes, to reduce exhaust gas temperatures at the tailpipe.

Perfect Fit:
This system uses all factory mounting locations providing stability and hassle-free installation. Includes OE-style bayonet hangers which 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.

6" Angle-Cut Rolled Edge Matte-Black Clamp-On Tips:
Finishing off the exhaust are dual side exit 6" stainless steel clamp-on tips with a matte-black finish. A unique laser-cut aFe Power logo plate is riveted on for an aggressive style.
