  2. I like that...........

    I don't know if you are aware Paul, but Ghost/Phil has a really good version of the zorst as well......

    Anyway, I assume both the pipes are the same length as each other??.....

    ...and have you seen the modification to the header 'branch area' done by 470four on this forum.......at the moment I can't find it so it may have been deleted but I saved this pic of it.

  3. Glad you like,yes tuned lengths have been observed,Neil is an ex Motad R n D man,so he finds all this stuff frustratingly simple.that header mod is interesting.I assume this is for better gas flow?
     
  4. Header mod for improved gas flow, yes.......Darren/470four (before the poor bloke departed this world) indicated the mod worked well.......I believe he got the idea from Luigi Moto (but I can't be sure)......

    .....I guess Neil would be able to comment further........
