    FFS! "You're a loser" not "Your a loser" Almost get it right later in the sentence but spell it wrong.

    The "workshop" pictured makes reproduction parts (headsets and such like)

    They made 100 exhausts for us from a sample.

    It wasn't a particularly good exhaust, but it sold well.

    The Chrome is surprisingly durable.

    They churn out copies by the thousands there (expansion chambers, every thing)

    This particular workshop recently purchased water forming equipment and have started to copy some new designs (that are hand made in Europe) and bang out water formed copies for about €110

    It's a sore point with quite a few people.

    Unfortunatly the mufflers are "jam packed" with "pink bat" material and you need to repack them, but after that it's still a cheap pipe.

    labour in Europe is always going to be high, obviously they can set up & cut for a run & jig saving huge amounts compared to fitting to a scrooter for the first time under bodywork, but you are buying the development & for a pipe with muffler that is quite reasonable.

    The original would be a mission but then laser cut patterns, good jig, big box of slip-joints and mounting flanges, and a decent bloke with a TIG, and I can't see more than .5 day putting them together.

    I'm no expert in these things but did spend a year or so recently working in a shop that did a lot of sheet metal.

    I bought a "power bomb" brand pipe, actually I got it after a mate bent one of my rotary files, for a NSR125 I think. It had a hydro formed tapered head pipe and a mismatched junction to the diffuser section but it worked a treat. It would have cost something around $50-70 I think. Stupidly cheap considering what it takes to make a pipe from scratch.

    About 2 years ago, such pipes where about €600 (Yep $1200 NZ)

    Competition from cheap copies dragged that down.

    The interesting thing is the money these guys made from such "handmade" copies was invested in (like one "workshop") in water forming equipment.

    Now they are still copying, but the quality of the water formed chambers is incredible (and cheap)

    The first series of water formed chambers was total crap, but over two years they got it right.

    Of course it is supply on demand, but the sad bit is the guys who design the original get little to no money.

    There is a recent water formed copy that rivals the best hand made chamber I have seen. and at €110 (landed, at your door) it is hard for the customers to say no.

    But it is a copy, there is nothing original about it.

    That is the important difference.

    The same is true for cylinders (cast iron lined only at this stage, but in a few years, I am sure Nikasil will be able to be produced) as well as Cylinder heads....

    All straight copies of the originals.

    Here is a water formed copy of the first pic.

    The muffler is taken from another pipe design (which actually was taken from the AG Bell book), and the slip joint is taken from a "Falc" exhaust

    Just an amalimation of 3 designs, but the actual expansion chamber dimensions are the same as the first pic.

    This first hit the scene here about a year ago.

    6 months after the original.
