x2 aftermarket pipe and 44mm carb questions

[luke]

hi im new to the pwc world and i picked up a 91 x2 in the summer then a got a 86 x2 that kinda runs but it has a 44mm carb and a pipe on it my question is, can a keep the stock carb on the 91 and put the aftermarket pipe on it without doing any tuning or should i just put the 44mm carb and the pipe on all at once or should i just keep the 91 stock?

thanks

do it all at once , it would still work if you only install pipe , but not as good

will i have to jet the carb and do alot of tuning because even tho the 91 is stock it runs perfect and i hope by adding the pipe and carb it will stay running good
