FITMENT

  • Engineered as a high-performance upgrade for any aftermarket 5" exhaust system.
  • Fits perfectly with custom or aftermarket exhaust setups on Ford Powerstroke, Chevy/GMC Duramax, and Dodge Ram Cummins diesel trucks.
  • If you are retrofitting this onto a smaller factory OEM exhaust pipe, standard exhaust reducer adapters and custom fabrication will be required.

DESCRIPTION

Product Overview

  • Upgrading your diesel truck to a 5-inch exhaust lowers towing EGTs and improves turbo response, but straight-pipe setups create loud highway cabin drone. Traditional chambered mufflers cut noise, but they restrict airflow and trap heat.
  • The 5" Inlet/Outlet 30" Overall Performance Diesel Muffler offers a high-flow, quiet solution. Its extended 20-inch stainless steel body features a straight-through core packed with high-temperature insulation to eliminate cabin drone, lower backpressure, keep EGTs safe, and deliver a deep exhaust tone.

Key Features

  • Heavy-Duty Stainless Steel Build: Constructed from heavy-gauge stainless steel with reinforced end caps to handle severe exhaust heat and winter road salt corrosion.
  • Lowers Towing EGTs: Unrestricted inner core allows hot exhaust gases to exit rapidly, keeping Exhaust Gas Temperatures cool under heavy towing loads.
  • Straight-Through High-Flow Design: Features a 5-inch perforated straight-through inner core that maintains maximum exhaust gas velocity without power-robbing backpressure.
  • Extra-Length Drone Elimination: Extended 30-inch overall length provides extra dampening volume to eliminate harsh cabin drone during highway cruising and heavy towing.

FAQ

Q: Why choose a 30" overall length muffler instead of a shorter 20" model for a 5" exhaust?

A: 5" exhaust systems produce louder low-frequency sound waves than 4" setups. The extended 20" body (30" total) provides 50% more sound-dampening volume to eliminate harsh highway cabin drone effectively.

Q: Will this 5" muffler change my truck's exhaust tone at idle and low speeds?

A: At idle and light cruising, it smooths out harsh metallic rasps and gives your diesel engine a deep, clean rumble. Under full throttle, it opens up to let your engine growl and turbo whistle through clearly.

Q: How should I mount and support this 30" overall muffler under the truck?

A: You can weld universal stainless hanger rods directly to the reinforced body end caps, or use 5-inch heavy-duty rubber-isolated clamp hangers anywhere along the smooth outer body.

Q: What is the best clamp type to use if I don't want to weld this muffler?

A: We strongly recommend using 5-inch heavy-duty stainless steel lap-joint band clamps. They provide 360-degree sealing pressure over the slip-fit joints without crushing or distorting the pipe ends.
