| There are 2 or 3 different pipe options for the 999. Regardless of which one has been fitted, it should have been finished off with a replacement ECU. The exhaust swap has a greater effect on the 999's because it gets rid of the "cat".
They're not "chippable" and as such the whole unit needs swapping. Not cheap!!
They usually come free with the termis though.
There may be some id or part numbers on the ECU. It's at the side of the battery with two large multi pole connectors fastened to it.
If there are some, mail me them and I can possibly check which one you have. |
