    Haven't had it dynoed mate. It dose feel strong tho. Because I used the original headers, cut, re-routed, and welded. To stop then from rusting, as they are chromed mild steel, I had them Ceramic coated. I liked the finish so much I Had the whole system done. Every one should have this done:nod

    I applaud your creative efforts, but that has to be some of the worst welding I've ever seen! :eek1

    Please, for gods sake... put down the welder, and stick to the fiberglass... :lurk

    :lol3 I went to a lot of effort to keep the lumps on the outside where they will not impede gas flow. Low amps, and spot weld:lol3 I bought a TIG to do this job, but could not weld with it. In the interest of time and speed I used a $500 MIG.

    Tig's require skill and practise beyond self taught. For once, I will have do a tech course to master it.

    Even with flap disks this is the best I could do:D

    There's weight savings to be made.......

    Black ceramic would be worth a thought.

    Can you recommend a book or website for learning about how to do this kind of fiberglass work?

    I am, as usual, clueless. Lots of ideas, but no idea how to bring them to fruition.

    Beautiful work, BTW. :tb

    The technique is called "Lost Foam".

    Google "Lost Foam Molding" or similar terms and you should find a bunch.

    K2m,

    I don't think it's necessary to reroute the exhaust, I think by following the curve of the side plastics, one can gain at least 1 gallong to 1.5 gallon from each side.
    With firewall insulation and Akrapovic exhaust, there won't be any risk of fire from the rear.

    This solution would be far cheaper than trying to build or buy a new exhaust system.
    One can take a look at those rear tanks built by AfricanQueen (Germany), most of them are extensions of the side plastics and some add more space from nuderneath the saddle (yet anothe gallon), personally I could live with an overall capacity of 10 gallons.

    So my take is, the original exhaust setup (with Akras) can coexist with 3 additional gallons of fuel while retaining the original aesthetics of the beast.

    Did someone finaly get some dyno results from the home made, modified collector?
    I'm looking in to doing it myself but would hate to ruin a collector if the dyno result suc's in terms of engine life. losing some power would not be a big deal. losing fuel economy, engine life and torque IS a big deal :D

    Please let us know! :ear

    In the world of effecient collectors, the one pictured is not one of them.

    Burns Stainless present a very good example of a very effective 2-1 collector. I have used Burns products for several header projects and have been very happy with the results. There are other vendors out there also so Burns is only one example of a product offering.

    Does the one pictured work? Probably, and it may not work too bad either.... but I can say with some confidence that there are better solutions which would probably yeild a better outcome, ie flatter torque curve, soother/greater power delivery.
