Product Description
DIAMOND EYE K4211A is a 4.0" aluminized turbo-back, single-side exhaust system with a performance muffler for the first-gen Dodge Ram 2500/3500 5.9L Cummins. Mandrel-bent tubing reduces backpressure for quicker spool and a clean, classic Cummins tone while resisting corrosion and heat cycle fatigue.
FAQ: WILL THIS FIT MY TRUCK?
Yes—if you have a 1989–1993 Dodge Ram 2500/3500 5.9L Cummins 4x4. This kit is built for all cab/bed lengths on 4WD models (verify wheelbase and hanger condition during install).
FAQ: WHAT’S INCLUDED?
Turbo downpipe, intermediate pipe, muffler, tailpipe, tip/hardware (as supplied by Diamond Eye), and clamps/hangers to bolt up using factory-style locations. Always inspect the contents list on receipt.
FAQ: IS THIS CALIFORNIA LEGAL?
No. This is a performance turbo-back system and is not CARB-approved. It is not for sale or use on pollution-controlled vehicles in California.
