They come with a 1 year warranty.
Like everything in this sport, if you do some research you can save alot of money here and there. If you can fab your own stuff, (which I do alot) you can save more. If you want bling (or what everyone else has) then you can surely find it and pay for it.
Example: I use harbor freight tools for the Desert instead my MAC and SNAPON, if I lose one no biggie. Some parts and accessories for these machines are rediculous ($300 mirrors) give me a break
$100.00 exhaust tips (or more). come on!
My machine isn't fancy but does a good job.
