cutting is the quickest way. if you opt for a full removal, there are a few rivets that will kick your butt.
basically 4 rivets per side that hold a bracket containing two plastic pieces per side that the sway bar rides against. all this needs to be removed to pull the bar. you can easily get to half the rivets, the rest seem impossible. seems as though all the body plastic was installed after the the bar, which makes the job challenging. not worth the effort in my opinion.
once removed, you are left with two holes that need to be filled to eliminate snow getting in. i make block offs from plexi glass and rivet back in place with the stock brackets.
as for durability of aftermarket arms, i have had good luck with chromollytubes, bad luck with aluminum tubes. expensive for sure, weight savings hardly worth the cost, but they look cool.
better money would be spent on power increasing mods or replacing the rear skid.
if you opt for a cut and look for a replacement on ebay or elsewhere, you need a bar from a mtn sled due to the narrower ski stance.
