Not to be short with this answer; they all are best over the stock system. I looked at all their spec. and dyno readings. They are all about the same & priced high. After all the looking around. I just built my own twin system. With a cummins & straight out the back it really sounds different than all the others.
UPS trucks
The Dodge pickup trucks with Cummins engines are diesel turbocharger engines. They are built by the Cummins company and have been used in Dodge Ram trucks since 1989.
Only Dodge will honor the warranty.
Need to know if it has the Mack or Cummins engine in order to answer.
Not the F250, F350, etc. Dodge and Cummins just signed a multi year contract to keep the Cummins in the Dodge trucks.
You were only able to get a Cummins engine in a truck made by GMC up until 1987, and that was only in heavy duty Class 8 trucks made by GMC (e.g., GMC General, GMC Brigadier, GMC Astro, etc.).
1989
They have good power, but the engine is very heavy.They have good power, but the engine is very heavy.
The Cummins motor is not a "Dodge". Dodge does use the "b" series Cummins engine in its pick up trucks. Ford does use the Cummins in its F650 and larger trucks. NO, Ford never has used the Cummins Diesel as far as I know. Up until 2010 the Powerstroke was built by Navistar, formerly International Harvester. In 2010 Ford starting building the Powerstroke themselves but kept the name. Dodge uses the Cummins diesel and GM uses the Duramax which was designed jointly with isuzu.
1989 up till 1998.5 then they changed to 24 valve
Ford IS NOT putting Cummins in their trucks. Chrysler Corporation and Cummins Diesel Engines, Inc. just signed a multi-year contract to keep Cummins engines in Dodge Ram Heavy Duty trucks. You can get a Cummins diesel in a Ford F-650 or Ford F-750. The F-250, F-350, F-450, and F-550 all have the Powerstroke diesel engines.
The Ford Motor Company never bought Cummins, Inc. That said, Ford has used Cummins engines in some of its trucks.
