2022 F350 7.3l
High quality product super impressed. I did the install as a weekend warrior in my garage. Ended up taking me a couple of days but this isn't my day job. I added DEI wrap. Definitely needed a second set of hands to help mount the headers. If I did it again I would have left some of the original studs in for initial install placement. My only complaint is the instructions could have had a few more pictures and the band clamps that are included aren't great. I had to buy 3" exhaust reducer clamps to fully seal the system. Had a custom x pipe 3" to flow master 40s prior to this. This upgrade brought my truck to that next level. The truck is a monster now can feel more power in acceleration and it has alot more growl. I did throw CELs for the cats as this was a major change but added a tune and it resolved the issue. SW is amazing and will definitely be a repeat customer for my next project!
