The Honest Truth: Diesel vs. Gas Exhausts for the 2023+ F350
Share
There is a lot of confusion in the Super Duty community regarding exhaust systems. If you go on a forum, you'll see people talking about "straight pipes" and "deletes." But for the modern 2023–2025 Ford F350 owner who wants to keep their warranty and stay street-legal, the options are different.
For the 7.3L Gas V8, an exhaust system is a performance upgrade. It uncorks the engine, letting that massive V8 actually sound like a truck.
For the 6.7L Power Stroke Diesel, an exhaust system is a style upgrade. Because the emissions equipment (DPF/SCR) acts as a silencer, changing the tailpipe won't make the truck louder—but it will make it look significantly better. The factory tailpipe is small, ugly, and prone to rust. A DPF-Back System adds massive 5-inch tubing and a polished or black tip that matches the scale of the truck.
In this guide, we break down the benefits of upgrading your exhaust, the importance of "Vented Tips" for towing safety, and fitment tips for Dually (DRW) trucks.

Frequently Asked Questions (Exhausts)
Will a DPF-Back exhaust make my 6.7L diesel louder?
No. We want to be 100% transparent: The Diesel Particulate Filter (DPF) upstream does all the silencing. A DPF-back pipe is purely cosmetic. It replaces the stock aluminized steel pipe with rust-resistant T304 stainless steel and a massive tip for a custom look.
Does this require "Deleting" my truck?
No. All exhaust systems in this collection are Emissions Compliant. They do not tamper with the catalytic converter, DPF, or DEF system. They are legal in all 50 states and will not cause you to fail an inspection.
Will the tip melt my 5th Wheel?
It is a valid concern for Dually owners. Factory regeneration cycles produce extreme heat. We recommend Vented Tips (like those from Banks Power) which draw in cool ambient air to mix with the exhaust gas, lowering the exit temperature to protect your trailer fiberglass and mud flaps.
