    "Provides a significant HP gain"

    Ebay item#320333811002

    http://cgi.ebay.com/ebaymotors/ws/eB...1002&viewitem=

    Item description
    "One set of Factory Pipe manifolds for their GP1200R triple pipes.

    These manifolds have been machined - this reduces the effective length of the pipes. Provides a significant HP gain"

    Any one know something of this manifolds??? How many “significant” hp provides??? What gains it has??? I need to modify something in my factory pipes to use this manifolds???? Thanks for any information!!!…

    Boy this brings back memories, this is an old trick, 35 years ago I did the same thing to my 125 cc motocross bike.

    Shorten the lenth of the pipe and you will typically see a HP gain.

    It is my understanding Rius used a set simialr to this back when he was using FP triples on his GPR.

    Anway same concept now as 35 years ago.
