• Does not fit Cab & Chassis

Description

This 4"/5" Downpipe-Back Exhaust System is engineered as a direct replacement for the factory exhaust on 2020–2024 Ford F-250, F-350, and F-450 trucks equipped with the 6.7L Powerstroke diesel engine. The system replaces the exhaust components from after the downpipe to the tailpipe, delivering improved exhaust flow, reduced backpressure, and a more aggressive diesel sound.

Constructed from high-quality 409 stainless steel and featuring OE-style hangers, this exhaust system installs directly to factory mounting locations for a true bolt-on fit. Designed for off-road and performance-oriented applications, it’s an ideal upgrade for drivers looking to enhance both performance and sound.

Key Features

Complete Downpipe-Back Replacement
Replaces the factory exhaust from after the downpipe to the rear of the truck, including the mid-pipe, tail section, OEM-style hangers, and all required installation hardware for a seamless bolt-on installation.

Improved Exhaust Flow & Performance
Larger 4"/5" diameter piping significantly reduces exhaust backpressure, helping lower turbo strain while supporting improved throttle response, torque, and overall power potential.

Straight-Through / No Muffler Design
Muffler-delete configuration maximizes exhaust flow and delivers a deep, raw, and more pronounced diesel exhaust tone.

409 Stainless Steel Construction
Built to withstand high exhaust temperatures and harsh driving conditions, offering excellent durability and corrosion resistance.

Direct Bolt-On Installation
Utilizes factory mounting points and bolt-together connections—no cutting or welding required.

Tuner Required
DPF, CAT, SCR, and DOC deletions disable emissions sensors. A tuner with Powerstroke DPF delete capability ensures no check-engine lights or fault codes.

Note

This downpipe-back exhaust system is intended for off-road and competition use only. It is not legal for use on public roads and may not be compliant with local, state, or federal emissions regulations. Please verify vehicle fitment and local laws before purchase and installation.

FAQ

Q1: Will this exhaust system fit my truck?
A: This system is designed specifically for 2020–2024 Ford F-250, F-350, and F-450 trucks equipped with the 6.7L Powerstroke diesel engine. Please confirm your vehicle’s year, model, and engine before purchasing.

Q2: What does “downpipe-back” mean?
A: Downpipe-back means the system replaces the factory exhaust from after the downpipe to the tailpipe, including the mid-pipe and rear section. The factory downpipe itself is not included.

Q3: Is this a bolt-on installation?
A: Yes. The exhaust system uses OEM-style hangers and factory mounting points for a direct bolt-on installation. No cutting or welding is required.

Q4: Does this system include a muffler?
A: No. This is a straight-through, muffler-delete design, intended to maximize exhaust flow and deliver a louder, more aggressive diesel exhaust sound.

Q5: How loud is the exhaust compared to stock?
A: This system is significantly louder than the factory exhaust, especially under acceleration. It produces a deep, raw diesel tone and increased turbo sound. Sound levels may vary depending on other modifications.

Q6: Will this exhaust improve performance?
A: The larger 4"/5" diameter piping helps reduce exhaust backpressure, which can improve turbo response and support increased torque and power potential, especially on modified trucks.

Q7: What material is the exhaust made from?
A: The system is constructed from 409 stainless steel, offering excellent durability, heat resistance, and corrosion resistance for demanding driving conditions.

Q8: Is this exhaust street legal?
A: No. This exhaust system is intended for off-road and competition use only and may not be legal for use on public roads. Always check local, state, and federal regulations before installation.

Q9: Will this exhaust trigger a check engine light (CEL)?
A: A downpipe-back exhaust does not typically trigger a CEL on its own, as it does not modify sensors or emissions components upstream. However, results may vary depending on other vehicle modifications.
