Follow the above DIY. Fairly easy...took me 6 hrs since the driver side bolts underneath are hard to reach...you need a swivel joint and long extension to get around the drive shaft.
I wrapped mine and turned out great. I pulled them recently after 15k miles and the wrap held up well. I’ll post pics later
Edit: I posted the info below. Still follow the link DIY and take your time with the V-Band clamps so you don't strip anything. I could probably do this in 2 hours now that I've done it so many times, but took me a while the first time since I didn't want to mess anything up. Be patient.
