DESCRIPTION

Product Overview

• The stock emissions system behind the downpipe on 2019–2022 Dodge Ram 6.7L Cummins trucks is a major performance barrier. The heavy catalytic converter, DPF, SCR (DEF) unit, and chambered muffler trap extreme thermal energy, trigger frequent regens, and choke exhaust flow.
  
• The 4"/5" Downpipe-Back DPF & SCR Delete Race Pipe Kit provides this kit eliminates all restrictive mid-pipe and rear emissions components. By relieving backpressure at the source, it lowers towing EGTs, restores instant throttle response, unlocks better fuel economy, and delivers that unmistakable Cummins inline-6 turbo whistle and deep roar.

Key Features

• Premium T409 Stainless Steel: Mandrel-bent 4"/5" T409 stainless steel tubing built to withstand high heat, heavy towing vibrations, road salt, and long-term corrosion.
  
• Maximum Towing EGT Reduction: Removes intense backpressure right behind the downpipe, allowing exhaust gases to exit rapidly to sharply drop EGTs under heavy loads.
  
• Kill Active Regens & DEF Errors: Permanently eliminates fuel-wasting regeneration cycles and DEF system issues, boosting fuel efficiency (MPG) and preventing crankcase oil dilution.
  
• Complete Downpipe-Back Airflow: Replaces everything directly behind the OEM downpipe—deleting the restrictive catalytic converter, DPF, SCR (DEF system), and stock muffler.
  

FAQ

Q: What is the main advantage of a 5" Downpipe-Back system with a muffler over a no muffler 5" straight-pipe?

A: Both systems maximize airflow, lower EGTs, and eliminate emissions restrictions equally well. However, this kit includes a high-flow 5" performance muffler to absorb harsh exhaust rasps and eliminate annoying cabin drone during highway cruising or heavy towing.

Q: Does the 4"/5" performance muffler restrict exhaust flow or increase backpressure?

A: No. It features a full 4"/5" straight-through core design. Exhaust gases pass straight through without obstruction, tuning out harsh sound frequencies without slowing down exhaust velocity or trapping heat.

Q: What is the difference between a Downpipe-Back system and a Turbo-Back system?

A: Downpipe-Back system replaces all exhaust piping and emissions components behind your factory downpipe (retaining your OEM downpipe). A Turbo-Back system replaces the downpipe itself as well, connecting directly to the turbocharger turbine housing outlet.

Q: Do you recommend pairing this 4"/5" downpipe-back race pipe with an EGR Delete Kit?

A: Highly recommended. While this 4"/5" downpipe-back system frees exhaust flow, an EGR Delete Kit stops hot, soot-heavy gases from entering your intake manifold. Combining both keeps intake air cool and clean, prevents valve soot buildup, and offers complete engine protection.
