I'm planning to swap out the manifold head pipe assembly on a 2022 V7 850 Stone. I plan to paint the replacement and swap 'em out. I rarely work on cars/motorcycles but I've been successful on small jobs.
What do I need to know?
Will I need gaskets or any special tools or will it just plug n' play?
What paint is recommended for pipes? I have a can of VHT ceramic header paint.
Thank you for your patience.

Swap it out for what? Do you have chrome, and want flat...black or some color? (just curious).
Actually doing it is pretty simple. Remove the mufflers, then loosen the mid pipe and the headers. Sort of 'jiggle' everything loose at once. Installation is the opposite- start with the headers and add parts toward the back. Keep everything loose until it's all together then slowly tighten up the fittings so you don't put undue pressure on any given pipe or joint.
I don't know where the lambda sensors are, but pay attention that you don't damage them. They should unplug from the harness pretty easily, so just chase the wires back. Or unscrew them. Either way works.
Yes, you should probably replace the two manifold gaskets in the head. There are no other gaskets to replace- it is just piping.
No special tools- some wrenches is all you need. You might get some antisieze for when you reassemble.
After running it a bit, you should retorque the manifold gasket.

Okay, so one of the pipes had a dent in it when I bought the bike and then I accidently put my jacket against the same pipe and it melted a big glob of material on it. I just want to swap out the original manifold with another original. I bought one off eBay and just plan to rattle can it a flat black.
Your instructions make sense, thank you!

If I got rid of exhaust pipes every time I melted fabric onto them, eBay would be asking me to chip in for their server costs.
You can get melted materials off exhausts fairly easily…
…unlike dents.
Your black rattle can job will probably be as strong and long lasting as Guzzi’s own stock matte black treatment.

One thing I would recommend is do not put the factory V7 850 exhaust flange nuts back on as they rust. V85TT nuts fit, as I learned from this forum, and change the aesthetic a little bit, but they're much cleaner. Part number 2B007821. I purchased mine from AF1Racing.
