aFe POWER introduces an all new Rebel Series dual middle-side exit exhaust system for the 2014-2017 RAM 2500/3500 with V8-6.4L HEMI engine. This Rebel Series Catback is designed with dual black exhaust tips that exit in front of the rear passenger tire for a unique, aggressive look. The tips come with unique laser-etched aFe POWER logos on the side and are constructed from 304 stainless steel for durability. The exhaust system is constructed from 3-1/2" MIG-welded, mandrel bent stainless steel tubing for maximum flow, increased horsepower and torque. This kit uses a free-flowing muffler to absorb high pitch tones producing a powerful sound. The performance Catback exhaust system includes necessary hardware and clamps for a hassle-free install, with no cutting required making it a true bolt on system.

4" Dia. Black Middle-Side Exit Tips:

Finishing off the exhaust are dual 4" diameter black 304 stainless steel clamp-on tips with a laser-etched aFe POWER logo on the side for an aggressive style. The tips are designed to exit from in front of the rear passenger side tire for a unique custom look.

This Rebel Series exhaust system uses factory mounting locations providing stability and hassle-free installation.

Leak-Free Seal:

High quality band clamps are used for a complete 360-degree sealing surface eliminating leak paths.

Aggressive Sound:

A free-flowing stainless steel muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque. 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. This makes for an easy installation with no cutting required.
