Donaldo,

Those pipes look great on the 907;

Can you give us any more details on how you constructed them, materials used and what modification you needed to make them fit (other than the rear pegs)

Thanks,

O.K. guys I am traveling right now and will do a more detailed account with exhaust pics, materials used and measurements when I get back home. Meanwhile here is pic of the rear:)

Ciao

Hey Donaldo,

Those pipes do look great, and in fact the whole machine is very nice, very well done.

Others considering alternative pipes might try to get hold of a Limited system (eBay?). They appear stock but have a significantly larger outlet diameter. I put one on mine almost from new and have been very much pleased all these years.

I needed to rejet and fit a low-restriction air cleaner. I believe the header pipes are larger also, as the exhaust valves were bigger than the standard 750. Not sure if they'll work on a 906/907ie though.
