-I was wondering if there is an aftermarket exhaust for this machine on the market?
-Also is it bad to run the ngk iridium plugs on this machine?

Should beable to find an aftermarket exaust for it. Check in the Misc. Parts forum, and click on the parts links thread.

As for the spark plugs. It won't hurt your sled to run those.Iridium plugs are about the best plug you can buy. Just make sure you are running the proper plug number for your sled. Hope this helps

no one makes pipes for 440s.

is that an F-series sled, if not black magic has a set of pipes for zr 440's.

no one makes pipes for a 440 cuz there is no need for them, they race in the stock class.

i was saying that black magic does make pipes for the zr 440's, you'll have to excuse my ignorance of snocross rules, i don't watch or follow it. i imagine the pipes for the zr's are for people on the trails mostly that just want a little more out of it.
