you remember right for the slip ons, the SE high flow A/C I got for about $125 at a dealership having their aniversary sale, i think they run about 140 regularly, and the V&H Fuel Pak I picked up off of eBay for $210 shipped. It was brand new in the box and came from a store called eastern performance or powersports something like that. All said and done it ran about $600. I did all the installation myself, brainless stuff, so that saved me as well. Like you I was pinchin what pennies I could but still trying to get quality. I believe I accomplished that nicely. Let me know if i can help you out at all.
