FITMENT

• 2013-2018 6.7L Dodge Ram Cummins 2500 / 3500 Turbo Diesel.

• Does NOT fit trucks equipped with factory Rear Air Suspension or commercial Cab & Chassis (4500/5500) models.

DESCRIPTION

Product Overview

• While the 13–18 6.7L Ram boasts impressive factory power, its emissions system chokes it with failing DEF heaters, faulty quality sensors, and fragile NOx sensors that trigger 5-MPH Limp Modes.
• During use, factory DPF is continuously collecting irreversible ash until it becomes permanently plugged, making this 4" DP-Back pipe a simple bolt-on fix to replace the restrictive filters and rotting muffler in one go.

Key Features

• Premium T-409 Stainless Steel Built: Heavy-duty T-409 SS to provide superior heat resistance and protect your undercarriage from severe winter road salt and rust pitting.
• Dual-Component Deletion: Replaces the restrictive DPF canister, CAT and factory muffler with 4" DP-Back pipe flow for uninhibited power delivery.
• Aggressive Cummins Growl: Eliminating the factory muffler unlocks the true, thunderous tone of the 6.7L inline-six along with a crisp, whistling turbo spool that a muffled system can never match.
• Drastic EGT Reduction: Maximizing exhaust gas velocity eliminates excessive thermal buildup, significantly lowering sustained EGTs to protect turbo and head gasket when hauling heavy loads.

FAQ

Q: What factory components does this Downpipe-Back system replace?

A: It replaces everything after factory downpipe all the way to the exhaust tip. This means it physically deletes factory DPF canister, CAT converter, SCR assembly, and factory muffler.

Q: Does this kit fully solve the 13–18 DEF tank heater and quality sensor codes?

A: Yes. Running this system requires a delete tune that shuts off entire emissions logic, completely deactivating and ignoring the problematic DEF tank heater, faulty quality sensors, and fragile NOx sensors forever.

Q: Is a custom tuner required to run this pipe?

A: Yes. Removing these filters will instantly throw hard fault codes and trigger a 5-MPH Limp Mode. You must install a delete-capable tuner (EZ Lynk or Minimaxx Tuner V2 ) to turn off the emission monitoring cycles.

Q: Can I install this kit on a truck with factory rear air suspension?

A: No. Trucks with the factory-optional rear air suspension feature modified track bars and air spring brackets that will physically hit this 4" tailpipe routing. This kit is strictly for standard leaf-spring trucks.
