The 30-Minute Upgrade: Why Axle-Back Exhausts are Perfect for the F350
Share
You just spent $80,000+ on a 2023–2025 Ford F350 Super Duty. It looks like a beast... until you walk around to the back corner.
Sticking out from under the bed is a tiny, sad-looking exhaust pipe. On the diesel models, it looks like a "musket" barrel with awkward cooling vents. On the gas models, it’s just unfinished aluminized steel that starts rusting within a few months.
You want to fix the look, but you don't necessarily want to spend $1,000 replacing the entire exhaust system—especially if you're happy with the sound (or lack thereof).
The solution is an Axle-Back Exhaust System.
These kits are the "Bang for your Buck" champions of the exhaust world. By replacing only the visible piping from the rear axle to the bumper, you get the massive 5-inch or 6-inch tip you want, without paying for piping underneath the truck that no one sees. In this guide, we cover the ease of installation and the critical differences between Single Rear Wheel (SRW) and Dually (DRW) fitment.

Frequently Asked Questions (Axle-Backs)
Will an Axle-Back make my 6.7L Power Stroke louder?
No. The sound suppression on the diesel happens upstream in the DPF and SCR systems. Changing the tailpipe (Axle-Back) does not change the volume. It is purely for the custom look of a large-diameter tip.
Will it fit with my spare tire?
Yes. All our verified Axle-Back systems are mandrel-bent to follow the factory routing. They are designed to clear the factory 18" or 20" spare tire tucked underneath the bed. Note: If you are running an oversized 37" spare in the factory location, fitment may be tight.
Can I install this myself?
Absolutely. An Axle-Back is the easiest exhaust mod to install. You typically only need to loosen one clamp near the rear axle, slide the old tailpipe out of the rubber hangers, and slide the new one in. No cutting or welding is usually required.
