4" VS 5" Cummins Turbo Back Exhaust Comparison Video
A comparison video for a 4" TBE straight pipe vs 5" TBE straight pipe on a 24V Cummins. The in cab videos were done with the windows up. Didn't get a heavy acceleration video, don't really have the roads for it.





Dodge Cummins 3rd Gen Magnaflow 5" 304 Stainless Exhaust Look and Sound Comparison
Visual and sound comparison with the factory Exhaust. Exhaust system is the Magnaflow pro series MFL-17989. Truck is a 2006 5.9L CTD Auto Quad Cab Long Bed and is all stock except for the new Exhaust. I have only driven the truck for a few days since installing the new Exhaust system and it has slightly louder and much deeper tone from idle to 2000 rpm, normal driving. From to 2000-2800 it is considerably louder than stock and may not be for everyone. I plan on adding another video while driving as well.





5 inch exhaust discussion
My opinion of the 4 inch and 5 inch Exhaust





water washing the cummins exhaust
every once in a while i clean the inside of the muffler. water has carbon-scrubbing properties. also helps the Exhaust sound a little more raspier without sacrificing the volume level. It's a stainless steel Exhaust so no it's not going to rust out.
