What is this and why is it in my exhaust?
« on: 01 August 2018, 12:31:51 pm »
i own two fzs1000's one is a 2002 and another 2005. After fitting a new end can to the 2005 bike I noticed three pipes inside of a larger pipe in the collector box after the exup which I took a disliking to so I checked my 2002 bike and it doesn't have them.
To me the 2002 bike feels faster but I've not really taken the new one out properly so this might just be in my head although it seems the mixture screw plugs on the carbs have been drilled out but the slide spring and needle look stock so I don't think the carbs have been played with.


Are these pipes some kind of restriction or something? Would there be any benefit or reason to either leave them in or take them out?

Other than emissions does it do anything performance or noise wise? How did you go about removing it? Seems to be welded in...

Now I was perfectly happy with my exhaust until I saw this. Now I'll have to check mine...

So after a bit more reading on the forum it seems most of the catalytic converter is in the silencer and link pipe if I understand things right so leaving what's left in the collector box probably doesn't serve much purpose emissions wise although I admit I know sweet fa about this.


 Question is is there anything to be gained by removing what's left, a post last yeah ended without much conclusion on the matter. It must have some restriction effect as it is to a point reducing the space in the tube but is it noticeable either on power or noise on a un ivanised bike or an ivanised bike for that matter... those of you who have removed it why did you do it?

There will be a slight gain as it' more free flowing, don' think you would really notice it though.
