Product Description
DIAMOND EYE K5216A is a 5" aluminized steel turbo-back exhaust system for the 5.9L Cummins–powered 1998.5–2002 Ram 2500/3500. It includes a 4" downpipe and exits single, passenger side with a muffler for a deep, controlled tone. CNC mandrel-bent tubing improves flow, helps lower EGTs, and frees up horsepower on performance builds and tow rigs alike.
FAQ: WILL THIS FIT MY YEAR?
It’s a direct bolt-on for 1998.5–2002 (24-valve) 5.9L Cummins trucks (all cabs/bed lengths). For 1994–1997 (12-valve) trucks, use the HX40-downpipe variant (see cross-references) or convert the turbine outlet accordingly before installing.
FAQ: DOES IT INCLUDE A MUFFLER?
Yes—K5216A is the with-muffler configuration. A straight-pipe/replacement-pipe version is offered under K5216A-RP (see cross-references).
FAQ: WHAT ABOUT CALIFORNIA/CARB?
This kit is not CARB legal and is not for sale or use in California on pollution-controlled vehicles.
