Increased exhaust flow means improved torque, horsepower and lower EGT's. That's why your Cummins diesel needs the SATURN 4S turbo-back exhaust system by aFe Power. This exhaust is built from 4" mandrel-bent 409 stainless steel tubing and includes a muffler-delete pipe for optimum flow and a race-inspired, aggressive sound. This system does not include a tip. SATURN 4S exhaust systems are the perfect combination of performance, fit and value.
Installation is a Snap:
This SATURN 4S exhaust system includes an extension pipe to fit multiple cab configuration and uses factory mounting locations, providing stability and hassle-free installation. Cutting may be required for some wheelbases.
Quality OE style flange and band clamps are used for a complete 360 degree sealing surface.
A muffler delete-pipe is used in place of the muffler for a true race-inspired sound and maximum flow unleashing all available torque and horsepower from your rig.
OE style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The bayonet tip locks into the hanger bushing for an OE style fit that does not change with time.
Flow and Performance:
Constructed of 4" mandrel bent 409 stainless steel tubing for longevity, the smooth transition bends result in increased exhaust flow and lower EGT's for improved throttle response and overall sound and performance.
