Who makes 2 fin center only diffusers?

[bquicksilver]

I'm looking to purchase a diffuser without the wings over the exhaust. The OEM BMW just doesn't look right with the 3 fins (i understand fit is great).

My question: Who all produces center only diffusers with 2 fins? I see the Autotecknic ones for $540. Are there other options? Do the Autotecknic ones fit poorly?

I'd like to know this also. I don't mind the 3 fin type so either for me. Must be available in the UK though.

If you like the 3 fin then it's a no-brainer to go with the OEM carbon unit.

It's a little tougher if you prefer 2 fins, hence the question.

I'd like to go for the OEM but we're not all rich unfortunately.

On the standard/stock diffu (without the centre fins) there are two what appear to be blank indentations in the plastic along the lines where two pre made fins could be affixed or super stuck on.
