Product Information

Product Description

 

Dyno Diesels Custom Exhaust System

Ram Cummins 2004–2024

Built for Cummins owners who demand maximum exhaust flow, durability, and a clean performance setup, the Dyno Diesels Custom Exhaust System is engineered to eliminate unnecessary restrictions while delivering reliable, high-flow performance. Designed with a prehistoric mindset—strong materials, simple construction, and relentless airflow—this system is built to perform in harsh conditions.

Certain stainless configurations and cab & chassis applications may be specialty-built to ensure proper fitment and performance.


Exhaust Material Options

Aluminized Steel 

A cost-effective, performance-proven option offering excellent strength. Aluminized steel may develop surface rust over time, particularly in harsh or wet environments.

T409 Stainless Steel

Recommended for trucks that see winter driving or salted roads. T409 stainless is magnetic by nature—this is normal and does not mean it is not stainless. Built to handle heat, moisture, and abuse while maintaining long-term structural integrity.

Use the drop-down menu to select your desired material and configuration.


Installation

  • Typical install time: 3–6 hours with basic hand tools
  • Can be installed in a driveway or garage (faster with an automotive lift)
  • Cutting may be required for certain cab/bed or shorter wheelbase configurations
  • Clamps, hangers, and hardware included
  • Some factory hardware may need to be reused

Designed for a straightforward, no-nonsense installation.


Features

  • No Bungs – Clean, race-ready configuration
  • With or Without Muffler – Configure sound level to your build
  • 4” or 5” Diameter Options – Built for serious airflow
  • OE-Style Hangers – Factory-style mounting for easier installation
  • Maximum Flow Design – Engineered for competition-style applications

This exhaust system reflects the Dyno Diesels prehistoric philosophy—simple, strong, and built to outlast modern restrictions.

Dyno Diesels — Ancient strength. Relentless flow. No extinction events.
