i got one from them, he narrowed it slightly for me so i have room for pipes
when you make yours i'd only mock it up then after you figure out the exhaust you know how wide the tank can be. also since you are making your own you can customize it for your fuel pump/feed/returns/sender/etc. that is awesome
