Fitment

FAQ: WILL THIS FIT MY 1998.5–2002 24V CUMMINS?
Yes—this kit is built for 1998.5–2002 Ram 2500/3500 5.9L 24V trucks (all cab/bed). Always confirm turbo outlet/downpipe style prior to installation.
FAQ: WHAT DOES "Muffler Replacement Pipe" MEAN?
It deletes the muffler section and replaces it with a straight pipe for the least backpressure and an aggressive exhaust note.
FAQ: CALIFORNIA / CARB?
Most turbo-back kits are not legal for sale on pollution-controlled vehicles in California. Check local and state laws before purchase.
