RAVE (Rotax Adjustable Variable Exhaust) but i don't know the HP, so i won't guess.

Yeah .. Bombardier won't comment on HP specs for their snowmachines because of all the variables. I asked about my own machine and they said too many factors affect performance, so they just don't do it. I think it's kinda silly myself .. if they specify it for a standard set of parameters such as elevation, ambient air temp, and grade of fuel .. then it's all good

Variable Exhaust systems (RAVE, VES, APV) restrict the exhaust opening prior to the pipe to allow a higher back pressure to increase bottom end power. As you open the throttle further, the valve becomes less and less restrictive, thus opening the port up entirely at WOT. Variable exhaust systems do not add HP to the sled overall but, dramatically affect the bottom-mid range of the engine on it's way to WOT.
By the way telorvehc2000, there are never stupid questions around here!
I just recently found out that Bombardier's reverse systems actually stop and spin their rotax motors backwards to do it! I had no idea until I asked. Someone on the forum answered me but I can't remember who it was anymore. Thanks again to whomever that was.

Just me trying to through things into different perspectives.
