I vote for the stock chargepipe.
Not advocating Mishimoto's chargepipe, but they had some data.
I'm sure its a good pipe, but have no experience with it.

Another update.
Have a perfect plug and play, modern horn!
Running both Fiamm 72102 (High) + 72112 (Low) with a splitter.
Will need a center bolt/nut to hold the included brackets to fit onto stock mount (not included).
Will mount onto car 2mrrw, see how it fits.
Fiamm Dual sound...
Splicing is no longer needed! ?
(If just swapping)
Found a Plug and Play connector......
Did some measurements and the VAG/VW/Audi/Porsche connector fits perfect!
Should plug into any universal horn.

The BMW connector in the link doesnt work, as it is...
Since the white big wing 2.0 is no more...
