Full Akrapovic Added

[Grumpy Goat]

So, I bit the bullet and scrapped BMWs stock exhaust manifold and went with Akras Titanium headers. Would not have thought this would be the answer but, PROBLEM SOLVED. Not sure if there was maybe a cat restriction or that flapper was not fully opening but the problem is no longer there. It now pulls like a horse as far past 6K as you want to go.

Hmmm … question is, is it measurably faster than stock.

I have no interest in removing a stock part and adding aftermarket if it does nothing for performance, and that is why I would not buy a slip-on. But a full exhaust including headers … that is another matter. Only problem there is the cost vs actual gain in performance. I rather take that money, but a bit more in and buy another bike.

If not inconvenient, could you take a picture of the Akra headers next to the stock headers so that we might be able to guess at the reason for the re-release of the choke on power?
