Akrapovic headers arrived yesterday and im perplexed over this hole in the bottom of the midpipe right at manifold joint. Is this supposed to be here? If not, wat should i do?

It looks to me like someone drilled that for water drainage purposes.
If you don't like it, just take it to an engineer/welder that van tig weld titanium and have him seal it up, won't cost much at all.
Let us know how you get on.
 
I would have thought that to be a pilot hole for an O2 sensor. If it's facing down when installed, must not be that.
 
Not sure what that hole is for, but I would think that the last thing you would want is an exit point for super hot (~1200F.) exhaust gases that close to the exhaust port! But then again I am no expert.
 
Cool! Hey did you find a muffler to suit those awesome headers?
Cause im so excited, again on this thread :) lol

Akrapovic makes a titanium header for our bike?!?

Kiwi found it for me on ebay. $450 for header an midpipe. Muffler just ran me another $325

Not many, and now discontinued.

I thought that at first too but at the underneath, exactly, didnt make sense. We'll see if i can notice a leak-noise when muffler is installed. Doubt it but we'll see

Its at the beginning of the midpipe where tubes collect to 1, def no risk of damage that far away
