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.
This system is designed with Intercooling tailpipes, to reduce exhaust gas temperatures at the tailpipe.
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 Polished Clamp-On Tips:
Finishing off the exhaust are dual side exit 6" stainless steel clamp-on tips with a high luster polished finish. A unique laser-cut aFe Power logo plate is riveted on for an aggressive style.
