Hi guys.any advice on where I can get new header pipes as one of mine has a dent in it?
cheers in advance.

Try OTR?

About the same price as genuine parts at �180 for the pair, although they're bigger bore and made out of decent stainless that will stay shiny (unlike OE headers). However, if only one's is dented the Yamaha headers can be bought individually.

I believe CRD make some too and are sold through X-Racing?

Will these header pipes give some considerable increase in performance?
My mods are PCV + O2controller,Leovince X3,DNA stage 1+2
I want to purchase one more mod to give some more Hp/torque to my Xtx and i'm between a camshaft or the OTR header pipes but i don't know what to choose between these two...
Which do you suggest me to choose?
Cheers

Hi i am no expert on tuning but from what i have read over the years, this is my take on it. High performance cam shafts adjust the valve timing and the result is an increase in HP at a certain rpm usualy at high rpm for top speed, however you LOSE power at lower rpm . Cam shaft profile is only one part of the tuning process, the whole system needs to be matched together this means air flow thro the filter, back pressure of the exhaust and fuel mixture and final checking on a dyno. A mis match of any of the above can give negative results.

As a general rule the more air you can get through the engine and the exhaust the more power is available. I would go for the bigger pipes.
