Item Interest

ATTENTION: This item is located in Europe, Germany. I can ship all over Europe and in theory also to the US although the latter is probably less interesting due to customs duties and taxes.

Due to the sale of my 550i F10 LCI, I am selling the catted downpipes that I had installed on it. These fit any 550i or 650i (F10, F13) with the N53 TU engine (450hp).

The downpipes were installed for about 2 years in my car. These do not really wear, so should be considered as being as good as new.

The downpipes were made by the well-known US manufacturer AR Design. Here's a link where I bought these about 2 years ago; currently you have to count 1-2 months of waiting time as these are fabricated on order:

The downpipes increase the throttle response of the engine due to a quicker spool-up of the two turbochargers. They also decrease the back pressure and should therefore increase the longevity of the turbo chargers.

In addition, they net an increase of 35hp (I did a dyno before and after) with the appropriate remap.

Installation takes about 4h.

Initial price that I paid for them including import duties from the US was about 2.500 EUR.

I am selling these for 750 EUR plus postage.

Yes indeed, for US guys this is probably not so practical. I'm rather hoping for someone from Europe / UK to be interested in this, for them it should be a good deal.
