I just bought my first stand up and was wanting to make upgrades on can anyone help me out on what to get

550subman

I got the most joy out of a waterbix pipe and top loader intake grate. Good stuff. Next would have to be milled head then impeller ride plate big sump pump oh and a cheap upgrade I just did on mine was to make the hose that comes out the back of the exhaust pipe smaller gives u small power gains. Oh and check to see what plugs u have. I used to run the br8es but I swithched to b8es and it runs better. Hope this helps.
