    I had a couple of hours this afternoon to finally work on my own bike and tacked together a high pipe exhaust out of parts I had laying around. on my 91 R100. The header pipes are equal length.

    All I need to do is pull it off and weld up the holes where the cross over pipe were and finish welding it together.

    First let me say that looks really cool. What are those mufflers?

    Second, I'm a little concerned that routing the exhaust that close to the shock is going to cause it to run pretty hot and be fade-prone. If not, it'd at least reduce their rebuild life.

    Thanks. The mufflers are made in Italy by MAS Engineering. Not to worried about the shock. It's all in the open air.

    Very nice.
    Are the pipe lengths calculated to match the engine or are they just wrapped around the frame so they fit?

    If they're calculated, do you mind telling us the length?

    I was more concerned with getting them to fit and having both headers the same length. They are 58" long plus the mufflers which totals 75". Stock is around 63"(w/mufflers). This should give me lots of mid range power and sound great:D

    Headers would be to long to get everything to clear. Good idea though.

    That is awesome. Do you think it would work with an older - dual shock bike?

    This may be common knowledge, but is that a special valve cover, or some kind of add on to spread the pressure of the acorn nut to more of the cover?

    Exhaust is looking nice BTW. :clap

    The valve covers a 3 piece design made by Siebenrock in Germany and around 200.00 a side. Cool but not cheap.
