FITMENT
- 2011-2022 6.7L Ford Powerstroke F-250 / F-350 / F-450 Super Duty Diesel Pickup Truck.
- Note: This will NOT fit Cab & Chassis commercial style trucks.
DESCRIPTION
Product Overview
- Stop choking your high-horsepower 6.7L Powerstroke. The restrictive factory DPF/SCR setup traps extreme heat, spikes EGTs, and creates massive backpressure that robs your engine of true performance.
- The 5" Downpipe-Back Race Exhaust Kit completely replaces everything behind the turbo downpipe with high-volume, 5" straight piping. Deleting factory emissions restrictions and the muffler permanently kills power-robbing regen cycles, drops EGTs sharply, and allows your 6.7L V8 diesel to breathe freely.
Key Features
- High-Volume 5" Airflow: Upgrades your system to a massive 5-inch diameter for maximum exhaust velocity, ideal for high-horsepower builds and heavy towing.
- Drastically Lower EGTs: Eliminates backpressure and heat-trapping emissions units to sharply drop Exhaust Gas Temperatures under heavy load.
- Kill Power-Robbing Regens: Permanently eliminates active regeneration cycles to optimize fuel economy, power output, and engine longevity.
- Unleash Aggressive V8 Sound: Straight-pipe setup unlocks maximum exhaust flow, a deep muscle-truck growl, and screaming Ford turbo whistle.
FAQ
Q: Does the 5" muffler restrict exhaust flow or increase backpressure?
A: No. It features a full 5-inch straight-through core design. Exhaust gases pass straight through without obstruction, tuning the sound pitch without slowing down velocity.
Q: Does this 5" muffler use internal packing that can burn out over time?
A: No. It features a heavy-duty, louvers/perforated straight-through stainless steel core without fiberglass or cell packing. The acoustic tuning will not degrade or change over years of high-heat operation.
Q: How much heavier is this 5" stainless system compared to the stock exhaust?
A: It is actually significantly lighter. The factory 6.7L exhaust with its massive DPF, SCR, and stock muffler assembly weighs over 80–100 lbs. The Seguler 5" T409 stainless system reduces total vehicle weight by approximately 30–40 lbs.
Q: Does this kit fit both Short Bed and Long Bed Crew Cab models?
A: Yes. The kit includes straight extension pipe sections designed to accommodate various wheelbases. For short-bed configurations, you simply cut a portion of the straight extension pipe according to the included instructions.
