Collection: Exhaust Systems

Technical Overview

Competition-grade diesel exhaust systems for Ford Powerstroke, Ram Cummins, GM Duramax, Mercedes Sprinter, and Nissan Cummins platforms. Turbo-back and downpipe-back layouts deliver high flow, quicker spool, and a deep diesel tone. Listings are organized by engine and model year for fast, accurate fitment.

Engineering and Design Advantage

Maximum Flow: 4" and 5" mandrel bends reduce backpressure for stronger mid-range and top-end.

Quicker Spool, Lower EGTs: Optimized routing improves scavenging and heat control under load.

Signature Tone: Aggressive diesel sound; muffler and straight-pipe options available.

Vehicle-Specific Fit: OEM-style hangers and brackets for direct bolt-on installs.

Durable Metals: T409/T304 stainless options resist corrosion and high temperatures.
