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
- Many diesel truck owners switch to a full 5" straight-pipe exhaust system to achieve faster turbo spool times, lower EGTs, and maximum horsepower.
- However, a full 5" straight pipe creates an aggressive, low-frequency cabin resonance (cab drone) that makes long-distance highway cruising or heavy towing deafening and exhausting for the driver.
- This 5" Straight-Through Performance Muffler is designed as the perfect solution. It splices seamlessly into your 5-inch straight-pipe setup to absorb harsh high-frequency noise and cabin drone, while maintaining a completely unrestricted exhaust path.
Key Features
- Heavy-Duty 409 Stainless: Built from heavy-duty 409 SS with robust TIG welds to withstand intense diesel EGTs and resist structural cracking and road-salt corrosion.
- Drone-Free Acoustics: Packed with high-density acoustic fiberglass to aggressively target and eliminate deafening interior cab drone and raspy tones during heavy towing or highway cruising, leaving only a refined, deep diesel rumble.
- Blow-Out Proof Protection: The perforated inner core is tightly wrapped in a premium stainless steel mesh shield before the fiberglass packing, preventing the sound-dampening material from eroding or blowing out under high-pressure exhaust pulses.
- Universal Reversible Design: Engineered with a symmetrical center-in/center-out layout and no directional flow restrictions, making it a seamless weld-in or clamp-on upgrade for any aftermarket 5" exhaust system.
FAQ
Q: Does it matter which way I install this muffler?
A: No. It features a completely non-directional, symmetrical design. You can flip and install it in whichever direction fits your undercarriage piping and bracket layout best.
Q: Will this straight-through design restrict my 5" exhaust flow or raise my EGTs?
A: Not at all. Unlike highly restrictive factory baffled mufflers, this performance upgrade features a massive, 5-inch straight-through perforated core. Exhaust gases pass through completely unobstructed, meaning you maintain the ultra-low backpressure and cold EGTs of a race-style system.
Q: Will this fit my stock diesel truck's factory exhaust?
A: Generally, no. Factory systems on most trucks are smaller (3.5" or 4"). This universal muffler is engineered for aftermarket 5-inch exhaust systems. Adapting it to a smaller factory pipe requires step-down adapters and custom welding.
Q: Which is better for my truck: a 4-inch or 5-inch exhaust setup?
A: It depends on your power goals. Choose 4" muffler (under 500 HP) to maintain ideal exhaust velocity and sharp low-end towing torque. Upgrade to 5" muffler (500+ HP, larger turbos) to maximize top-end airflow and dump extreme heat fast—just note it is much louder and more prone to cab drone.
