Dyno Diesels Custom Stainless Exhaust System

Engineered for Maximum Flow. Built for Real-World Performance.

Dyno Diesels exhaust systems are engineered with a dyno-first mindset—designed to reduce restriction, improve exhaust flow, and deliver consistent performance under load. Each system is built using high-quality materials and precision fitment to ensure durability, proper routing, and long-term reliability.

Certain stainless configurations and cab & chassis applications may be specialty-built to match wheelbase, body length, or chassis layout.

Shipping

• Ships via ground service

• Typical delivery time: 5–7 business days

Exhaust Material Options

Aluminized Steel (Most Popular)

A cost-effective performance option offering excellent strength and heat resistance. Aluminized steel may develop surface rust over time, especially 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 withstand heat, moisture, and vibration while offering improved long-term durability.

Installation

• Approximate 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.

Exhaust System Overview

Dyno Diesels exhaust systems are built to support tuned, deleted, towing, and competition-style applications. By replacing restrictive factory components, these systems allow exhaust gases to exit efficiently—reducing backpressure and supporting improved engine efficiency.

Available in 4” or 5” diameter, each system is designed to deliver consistent flow and durability where it matters most.
