2003-2004 Cummins 4" Turbo Back Exhaust System w/ Muffler (48643)

Fits

Moves up to 122% better than stock and eliminates backpressure in your Ram 2500/3500 with the Banks Power 48643 Monster exhaust system. The streamlined 4" turbine outlet pipe (with provision to retain stock catalytic converter), intermediate pipe(s), and tailpipe are made of heavy-wall, stainless tubing with constant-diameter bends to maximize airflow and lower EGTs.

Replace the restrictive factory muffler in your 2003 - 2004 Dodge Ram with the Banks 48643 polished-stainless Monster muffler featuring a straight-through 4" diameter path that flows up to 129% better. The Banks-designed expansion chamber will dissipate the annoying exhaust drone that plagues most straight-through mufflers. The Monster muffler utilizes spun ceramic, high-temperature packing and gives your Dodge truck a rich exhaust sound. The tip comes with an adjustable clamp for positioning on the tailpipe.
