Frequently Asked Questions
Will this catback fit my 2020–26 F-250 or F-350 Super Duty?
Yes. This catback exhaust is designed specifically for the 2020–2026 Ford F-250 and F-350 Super Duty trucks equipped with the 7.3L Godzilla engine. It is compatible with all cab and bed configurations and is a direct bolt-on system. See the Fitment Information section above for wheelbase details.
What is the difference between Legend and Redline?
Both series are engineered to deliver an aggressive exhaust note. The Legend Series offers a classic muscle car tone with a deep, refined sound. The Redline Series delivers a more aggressive, race-inspired sound profile for maximum attitude.
Will this system fit with the 5th Wheel Prep package?
No. This system does not fit trucks with the 5th Wheel Prep package. The tailpipes will hit the added components, so this system will not work out of the box on those configurations.
What warranty is included?
Stainless Works provides a lifetime warranty on material and craftsmanship — covering the full life of the product, not just a limited term.

Catback & resonator delete
Verified Buyer — Dave | Aug 2nd 2026
I did the entire exhaust from the heads to the tailpipe exits on a 24 F250 Superduty Tremor 7.3L gas truck. Before, it was grandpa's work truck. Now, its a freaking beast! I also added a supercharger so I wasn't chasing sound improvement so much as I was looking for flow performance. And SW pipes did not disappoint. Opted for the Legend package because i didnt want the truck too loud. I can not say enough good things about this setup! There is zero drone. Pipes arent loud. You can hear a lil rumble. When you get heavy on the pedal the truck comes alive and it will get a lil loud! But that's ok cause that beast is breathing! It's very B.A.!! And none of that affects drivability or dependability. It still hauls & tows with ease...actually even better. And judging from other folks with the same package online, it is now 0-60 in about 4.5 seconds!! Not bad for a 7000lb brick!

Legend 7.3 Cat Back System
Verified Buyer — Nick | October 21, 2025
I just finished up the installation of the Legend cat back for the 7.3 v8. The product itself seems well made and I have zero leaks or needs to adjust anything which is a testament to the fit and finish of the product. It produces a pleasant muscular sound upon start up and settles down nicely. I wasn't looking for anything super aggressive or prone to drone. My one complaint is with the instructions. I feel for the cost of the system the instructions could be a bit clearer and have a few full page color printed pictures. Due to the system using some hanger systems the truck doesn't come with from Ford a clearer picture of their orientation and the proper orientation of the proper piping angles would have been helpful. After scouring the Internet I was able to locate some pictures from other customers which helped.

2022 F350 Lariat 7.3L Legend Series Cat-Back
Verified Buyer — Mike | March 10, 2023
Love the exhaust. I have had two other vehicles with Stainless Works headers before and loved the products. This was my first cat back with them and I am very happy. Great cold start and minimal drone even when towing 15k. Highly recommend. Also great support over email and phone. Look forward to future products as well.
