Unlock Hidden Performance: Eliminate restrictive factory DPF & CAT to reduce backpressure, unlock hidden horsepower, and improve throttle response.
Built to Last: Crafted from high-quality, corrosion-resistant T409 stainless steel with full 4" mandrel-bent tubing for maximum durability and optimal exhaust flow.
Simple Bolt-On Design: Features OEM-style 4-bolt flanges and factory-style hangers for a seamless, direct-fit installation. No cutting or welding required.
Precision Fitment for L5P Duramax: Specifically engineered for 2017-2025 Chevy Silverado & GMC Sierra 2500HD/3500HD with the 6.6L L5P Duramax diesel engine.
⚠️ Off-Road Use Only – Tuner Required: Designed for off-road/racing use. An aftermarket engine tuner is REQUIRED to disable DPF regeneration and check engine lights.

Maximize Towing & Hauling Power: Engineered to drastically reduce exhaust backpressure under heavy load, unlocking significant torque and horsepower for your Cummins when you need it most.
Critical Lower EGTs for Engine Health: Straight-through design dramatically lowers Exhaust Gas Temperatures (EGTs), protecting your engine during demanding off-road towing or heavy hauling.
Built for the Long Haul: Constructed from heavy-duty, corrosion-resistant T409 stainless steel with full 4" mandrel-bent tubing to withstand extreme heat and harsh conditions.
Simple, Direct Bolt-On Design: Features OEM-style 4-bolt flanges and factory-style hangers for a seamless installation. No cutting or welding required.
⚠️ Off-Road Use Only – Tuner Required: This delete pipe is for off-road/racing use only. An aftermarket engine tuner is REQUIRED to disable DPF regeneration and check engine lights.

Sharpen Throttle Response & Turbo Spool: Engineered to minimize exhaust restriction, allowing your Powerstroke's turbo to spool up faster for immediate power delivery and a more responsive driving feel.
Optimize for Daily Driving & Towing: Reduces backpressure across the entire RPM range, improving engine efficiency for better fuel economy during daily commutes and unlocking power when you need it for towing.
Lightweight, High-Flow 4" Construction: Crafted from durable T409 stainless steel with mandrel-bent tubing. Saves significant weight over the bulky factory system while maximizing exhaust flow.
Simplified Installation, Direct Fit: A direct bolt-on design using OEM-style 4-bolt flanges and factory hanger locations. No cutting or welding required for a straightforward upgrade.
⚠️ Off-Road Use Only – Tuner Required: This delete pipe is for off-road/racing use only. An aftermarket engine tuner is REQUIRED to disable DPF regeneration and check engine lights.

Uncork Turbocharged Power at the Source: Replaces the restrictive factory DOC (Diesel Oxidation Catalyst) directly at the turbo outlet, eliminating the first major bottleneck in your L5P's exhaust system.
Up to 20% Improved Exhaust Flow: Engineered with smooth 3.5" mandrel-bent tubing to significantly reduce backpressure immediately after the turbo, allowing for quicker spool-up and increased horsepower.
Heat Management is Key: Includes high-quality heat wrap to reduce under-hood temperatures, improve exhaust velocity, and protect vital engine components from heat soak.
Direct Bolt-On Installation: Features a factory-style 4-bolt turbo flange with pre-installed studs for a straightforward, hassle-free installation using basic hand tools.
⚠️ Off-Road Use Only – Tuner Required: This downpipe is for off-road/racing use only. Custom tuning is REQUIRED to prevent check engine lights and optimize performance gains.

Enhance Your Diesel's Aggressive Sound: Engineered to deliver a deep, aggressive exhaust tone while eliminating the raspy, high-frequency noises associated with straight pipes.
True Straight-Through Performance: Unrestricted 5" straight-through design maximizes exhaust flow, reducing backpressure and allowing your engine to breathe freely for optimal performance.
Universal Fit for Popular Diesel Trucks: Designed to fit a wide range of diesel applications including Ram Cummins, Ford Powerstroke, and Chevy/GMC Duramax. Works with both factory and aftermarket exhaust systems.
Premium T409 Stainless Steel with Mesh Wrap: Built from corrosion-resistant T409 stainless steel with stainless steel mesh and fiberglass packing for superior durability and sound absorption.
⚠️ Off-Road Use Only: This muffler is designed for off-road/racing use only. Professional installation recommended for best results.

Race-Ready 5" Exhaust System: Complete downpipe-back system engineered for maximum flow. Designed for competition and high-performance off-road use where every horsepower counts.
Complete DPF, CAT & SCR Removal: This full system eliminates all factory emissions equipment from the downpipe to the tailpipe, providing the ultimate unrestricted exhaust path for your Cummins.
Uninterrupted Flow Design: No bungs or obstructions in the exhaust path. The smooth, mandrel-bent 5" stainless steel tubing ensures minimal backpressure for peak turbo efficiency.
Precision Fitment for Ram Cummins: Specifically engineered for 2019-2024 Ram 2500/3500 pickups with the 6.7L Cummins diesel engine. Includes OE-style hangers for a factory-like fit. (Does NOT fit Air-Ride or Cab & Chassis).
⚠️ Off-Road Race Use Only – Tuner Required: This complete system is for off-road/racing use only. Custom tuning is REQUIRED to disable emissions systems and optimize performance gains.
