Hi Guys,

Does anyone has any experience with this product:

Seems like full setup will give you 8.4HP more

Cheers,

I don't, but that is one great looking pipe! I hope somebody can offer some insight.

Just fitted one,with eprom chip. Bike has a real bark now,sounds the way it should! Not sure about perfomance difference yet but I do feel the throttle response is much smoother. I realise your post was a while ago so I hope this is still relevent
