Ford 7.3L Long Tube Headers
Verified Buyer — Dave | Aug 2nd 2026
I had long tube headers from SW installed on a 6.2L Raptor years ago so I knew what to expect. SW headers have the thickest head side flanges ive ever seen! No chance of warping or leaks if installed correctly. For the 7.3L I opted for 1 7/8" primaries since I also installed a supercharger. The 7.3L is in a SuperDuty with 4.30 gears and it absolutely rips!! The pipes are not loud but flow excellent! The supercharger whine is louder then the headers. This time I had a shop install the headers because in modern cars/trucks its a pain to do in the driveway. Doable but easier to pay someone. Ive had SW lingtubes on 2 trucks now. Top quality! No rusting! Perfect fit! Unbelievable flow! A must buy if youre lookin for pipes!

2022 F350 7.3L
Verified Buyer — Joe Kelly | May 1, 2023
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!
