I've been running the Mac cat deletes for about 3 years on my car. No major complaints besides the exhaust gaskets. I don't remember what I paid but maybe around 2-3 hundred bucks. I'll take some photos when I put my car on a lift
I'm actually having raffle for a ceramic coating package next week
50 people x $20
It will include a 2 atep paint correction and ceramic coating for paint, wheels, glass,wheels, and trim. DM for details
