GPPExhaust Manifold Kit Set Compatible with 1999.5-2003 Ford 7.3L Powerstroke Diesel

Perfect fit for 2003 F-250 7.3. Good bit of work to get them installed but everything went together fine to replace the worn-out manifolds. I would definitely recommend them to friends.

bolt up nicely i was a little skeptical about the gaskets but they sealed up good if you have an older truck and are looking to install an egt gauge just do your self a big favor and buy these drill and tap these then install on truck . one side note while you have the manifolds off good time to do the up pipes.

i have not mounted these parts yet but i did notice that these will have to be ground out for max. flow

Installed without many issues. Just the typical tedious work that comes with a 20 year old truck.Ther product itself seems fine. Matched the quality of OEM as far as far as I can see. I had a question or two and users here were great to answer. If you need manifolds, I would recommend these.

Nice looking product fits good but Amazon driver threw my package out and ripped my gaskets so beware must be to heavy for most so they just kick out the back of these van

It took us weeks to get the truck in the shop being they were so busy so we lost our window to return..The one side did not line up even with many efforts by the garage. Had to purchase another one to get the truck completed. Do not recommend, go through the dealer, maybe more money for the parts but they will fit and be less complicated.

A better fit than I expected. They are great. If you do not have experience with working on exhaust or lots of experience, then get help from someone who does. A lot of disassembly to install these.

Did what it was supposed to do. No issues
