Product Description
DIAMOND EYE K4212S-RP is a 4.0" T409 stainless turbo-back exhaust system for 1994–2002 Dodge Ram 2500/3500 5.9L Cummins, configured without a muffler for maximum flow and an aggressive tone. It includes the turbo-back piping (downpipe to tail), single side exit, and uses mandrel-bent tubing for lower EGTs and improved throttle response.
FAQ: WILL THIS FIT MY TRUCK?
Yes, if you have a 1994–2002 Ram 2500/3500 with the 5.9L Cummins (all cab/bed lengths). 1998.5–2002 24-valve trucks are a direct match; 1994–1998 12-valve fitment is also supported per kit family coverage. Always verify emissions/local laws before purchase.
FAQ: DOES THIS KIT INCLUDE A MUFFLER?
No. The -RP designation means muffler replacement pipe (straight pipe). If you want a version with a muffler, see the stainless K4212S kit variant.
FAQ: WHAT MATERIAL IS USED?
T409 stainless steel for strong corrosion resistance and long service life. Natural (uncoated) finish.
