919 Firblade Custom Exhaust Spec - Advice Please
Hi All.
I have a live axle Westfield SEW with a 919 fireblade engine fitted.
The engine has been jetted by AB Performance and I am running the standard fireblade airbox.
The exhaust system I have is pretty crap and too restrictive, so I am going to make a new custom one.
Can anyone offer advice on the best pipe diameter to use? plus any details on pipe length/equal length etc.? I have an AB performance supplied
silencer which I'll be using. Basically looking for optimum performance considering the rest of the setup I have.
Any help would be great. Thanks, Anthony,

I used a zx9 ef model for mine with the larger bores and mid range pipes. Works well
Think about it, think about it again and then do it.

Thanks KJ,
Please can you advise exactly what you mean by a zx9 ef model?
Do you have any details on the diameter/length of the pipework? plus any pics would be great.
Thanks very much.

My engine is from the c model and the e\f uses bigger bores and has a link tube between 1 & 4 and between 2 & 3 for more mid range.
Think about it, think about it again and then do it.

This was the first one, its stainless steel so you can weld them.

I used the standard E/F headers on mine, made for a simple install, and worked well. The linked pipes make a big difference to mid range.
