01 600 grizzly snorkel advice

Hey everyone I’m looking to snorkel my grizzly I just got 2weeks ago I’m looking at maybe doing away with the air box and going straight from the carb and putting a filter on the end of the pipe I know it’s not the best looking just haven’t snorkeled one before and I have seen other wheelers with that set up and I really don’t know how to seal the original snorkel hole and do I have to take the cvt cover off and rtv it as well or is it already sealed any and all advice will be greatly appreciated I know I sound a little cheap but I’m bogging on a budget thanks in advance.
