Nothing changes as it is the same exit after the Cat with the Arro headers (without the Cat), so I presume you can still fit the CF protectors. My original CF protector still fits.

Bought it from Italy on Ebay from this seller: http://www.ebay.it/itm/ws/eBayISAPI.dll ... TQ:IT:1123

When you buy a bike and pay for it fully, Its like putting down the first down payment, with many more to follow...

i bought my bike in full cash payment with a good deal savin me 800 quid, so i justify my spending on my exhaust as really buying my bike for book price and not really losing anything, although the spending has begun and no doubt al be spending a few quid more, sooner than later if companys would pull there finger out and produce more stuff for the bike right now! :x

OEM torque setting for exhaust manifold bolts on BMW F800 cylinder head is 15nm.

I'll post here and under Other thread 'fix/mod/tip of the day' (until merged).

I've ordered Arrow Collectors and had planned to simply cable-tie the exhaust valves when new pipe fitted as described in the 'how to'.

I know that you need to swap over the O2 sensor from old collector pipe into new.

Unless I'm getting confused (and using the method described in the other thread) when removing the OEM Collectors can I not simply leave the valves/cables etc attached and simply disconnect the wiring and seal with silicone as suggested (rather than to have to unscrew the valves/cables and hide away?

Just seems neater to me and without it being any trouble to re-construct if OEM pipe needs to go back on for any reason? Just put the old pipe back on, remove sealant and plug back in?

I've not got the bike sitting in front of me so am going from memory, is this not more straight forward?

No slicing of wires or harnesses I take it?

And can I add this, having fitted my Arrow collectors tonight.

Remember to use heat/anti-seize grease when re-assembling exhaust clamps etc.

Is worth buying 4 new exhaust manifold nuts, they're made of copper or similar and thus softer/more easily rounded by definition. They're £1 each and are OEM on many BMW's, obviously F800. Nothing worse than rounding-off manifold nuts.

I had a look at removing the valve cables completely and/or removing motor box ~ isn't worth the trouble and as CSL suggests, it is far more simple to cable tie the two cables together and simply tuck up inside the bike securing by means of cable tie. Best done when original collectors have been removed & before new ones fitted.

Arrow, top quality fit, very impressive ~ excellent quality and certainly nothing like a poor, after market item a I've seen on many occasions.

My O2 sensor offered no real resistance, none at all in fact. 22mm spanner with good long handle will do it.

I'll comment elsewhere re; what difference it makes.

My arrow system arrived last Thursday.

Prior to fitting mine I have a few questions.

CSL you mention that there are no manifold gaskets. Were there any on the stock headers when you removed them?

How east is it to align everything correctly?
