" It turns that in sometime in 2011, they changed from a flange on the downpipes to a slip joint. Well, as you guessed, I got a flanged set and need a slip joint.

The response from EFI-Logic was exactly what you would hope for. Basically, no problem, send them back and we will get a new set out to you. I can't do the install again until June, so they can schedule their shop time.

Once they are in, I will let you know the results. "

" My EFI-Logic downpipes have arrived for my 2012 X5 50i.

My initial impression is that they are well made. Nice thick flanges, nice welds, well packaged.

I was happy dealing with EFI-Logic. They delivered exactly when agreed and packaged everything well.

Hopefully, I can beat the rain and get them installed today. "
