DIAMOND EYE K4212A TURBO BACK EXHAUST 94–02 RAM 2500/3500 4 INCH SINGLE IN/SINGLE OUT PASS WITH MUFFLER ALUMINIZED

DIAMOND EYE K4212A is a 4.0" aluminized turbo-back single-side exhaust system for 1994–2002 Ram 2500/3500 5.9L Cummins. It replaces restrictive factory tubing with mandrel-bent 4" piping and a performance muffler to improve flow, lower EGTs, and give your second-gen a deep, authoritative tone.

FAQ: WILL THIS FIT MY TRUCK?

It’s designed for 1994–2002 Ram 2500/3500 with the 5.9L Cummins (all cab/bed). Many catalogs list 1998.5–2002 as the primary fitment; earlier 1994–1997 trucks may require model-year specific hangers/hardware. Always verify downpipe/turbo outlet and hanger style for your build.

FAQ: DOES IT INCLUDE A MUFFLER?

Yes—this K4212A kit includes a performance muffler. (If you want a no-muffler version, see the Diamond Eye K4212A-RP on our site.)

FAQ: WHAT MATERIAL IS IT?

Aluminized steel (performance series) for strong value and corrosion resistance. If you prefer stainless, consider the MBRP XP/Pro cross-references below.
