aFe Power Rebel XD Series 4" Stainless DPF-Back w/Black Tips | 2017+ 6.6L GM Silverado HD/Sierra HD L5P

Simple Installation
All systems use factory mounting locations providing stability and hassle-free installation.

Leak-Free Seal
High quality band clamps are included for a complete 360 degree sealing surface.

OE 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 & Peformance
This Rebel XD Series exhaust system is constructed of 4" mandrel-bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT’s.

5" Diameter Polished Intercooled Tips
Finishing off the exhaust are dual 5" diameter, Hi-Temp black, stainless steel straight cut tips with intercooling vents designed to reduce exhaust gas temperatures at the tailpipe. A unique stainless steel laser-cut black powder-coated aFe Power logo plate is riveted on for an aggressive style.
