Here is the skinny on these pipes...There are currently only 3 of these in existance, but THERE ARE 2 more being built as i type this. He has pieces to build about 15 total...EVER! The stamped center section is from an old school KTM dirt bike pipe, that has been discontinued...and the molds are long gone. He said he had 15 of these center section stampings still around, but when they are gone, THEY ARE GONE! So, that leaves only about 10 more of these pipes to be had (if he doesn't do any old school KTM pipes...LOL). As far as pre-orders go, Thats not something I will EVER get into. I have had too many "issues" in the past, when getting in on pre-orders. I would rather pay for them up-front, then sell them off to people who have money. Also, his busy season is the fall, winter, and early spring months. He is just starting to get busy with sled stuff again, so, other than the 2 he is working on now, there won't be any more of these pipes built until spring/summer of next year, AT THE EARLIEST! If people want to purchase one of these pipes next summer, start saving your money, and let me know that you are interested. Depending on how many more people want 1, Maybe we can get him to build another run of 5 next summer. I don't know if they can be had cheaper than $550 each or not (and he said he would have liked to get $600 each out of them, but I told him he was gonna price himself out of the market, no matter how good they are!). He did cut me a BIT of a deal on the first 3, but I left him a bike for over a month to use as a jig, Specified how I wanted them built, AND spent $250 in fuel to haul it back and forth to his shop....So I am still paying retail for my pipe, even after the few bucks I am gonna make on the other 2... So, ther ya have it...There will only ever be 15 of these pipes built...If that doesn't add some worth to them, I don't know what does!
