Fasmen or Fasmem

[nick.h]

brought a new exaust (fasmem duo) from ebay the other day. it only cost me 26 quid, is this a good price?

just wondering if its any good and if it will affect my bike in anyway, performance wise?

thanks nick

I'd think that the power delivery characteristics will be significantly altered as you are chagning the timing of the pressure waves. Having two pipes will not necessarily make your bike more powerful. In some instances, it will hamper performance - i've heard about a guy that put a leo vinci on his gilera runner and it ran slower.

A pipe with a smaller bore will generally have better acceleration at the expense of top end etc. If you want to, you can read the Hayne's motorcyle book at waterstones or any good bookshop and read the section on 2 stroke tuning about it!

The setup looks cool, but i'm a bit suspicious about the finishing of the welds, but at 26 quid, your bike will look cooler in my opinion.

I have never known of any 2 stroke pipe with twin pipes from one expansion chamber that has increased power. They do look cool, but often make you go slower!
