18" rear wheels, Aftermarket exhaust, What sprocket size??

About to get my pipe and get my rear hipers next month. Just curious what sprocket I will need to run.
Mainly will do MX riding. Will put my 14 or 13 back on w/ my 20's when I do some trails and dune riding.

Someone from another site said 15 tooth. Hm maybe add one of those to my collection :) Would 2 inch smaller rear tires equal about 1 tooth smaller front?

Tim farr runs stock gearing with 18 inch rears but has more motor than us. I run a 14/39 gearing with 18 inch rears and it feels great.

I would think the 18's would make the gearing not so tall and be about perfect. I hate how tall the gearing is on mine.

stock gearing is perfect with the 18's
