Im saving up to buy a new exhaust and I was wondering if anyone could let me know how many things I need to purchase for my machine to be able to compensate for the new exhaust. I was searching online and was overwhelmed because I'm not sure what is a necessity and what is just extra. So far the items I have on my list to purchase for the new exhaust are, a new jetting kick and a fuel optimizer. Is this all I need? please feel free to express your nerdy needs I need as much information as possible.
