Here is a before and after picture:



Exhaust is Eisenmann 4 x 76mm.

A couple of comments on the fitment:
There are a few 'clips' along the edge of the diffuser that go into the m-aero rear bumper; one of them has to be broken off so that it will fit. The diffuser is made out of fiberglass and doesn't have much 'give'. To make it fit, it has to be put under relatively high strain. It kind of feels like it would pop out at any moment. Also, if you get the Eisenmann exhaust, part of the diffuser conflicts with the right half of the exhuast and a 3"x3" square needs to be cut off.

As a last note to people contemplating buying this diffuser, I would recommend that you get the 4 x 90mm Hamann exhaust to complement the diffuser (like a fellow member aR. did), as the Eisenmann exhaust looks too small. Unfortunately, the 90mm exhaust is only avaliable for the 550i...

Good night y'all.

 

Very nice change
Congrats

 

looks awesome owen, those custom fees are a b&tch! if it wasnt for that you would have gotten a steal.

 

looks great
quick question, why didnt you get it from quad m. he probably could've avoid you those custom fees.

 

looks good man . im gonna see it at the next meet right? only thing that sucks are the "extra fees".

 

Looks great. Thats my favorite diffuser. Those custom fees are ridiculous.

 

I wasn't aware that quad_m could get ahold of the diffuser. I was under the impression that the only stock of the item was in Germany and that I might as well just buy it directly from Hamann. As much as I like the idea of someone else paying the custom fees, that wouldn't be quite fair, would it?

 

Great thread and def an improvement.


Where did you get your 1st diffuser with the dual cut-out? Is that custom made from the factory Mtech diffuser? Is it for sale?

 

I got the first diffuser from Eurorev (www.eurorev.com). It is custom made. It is also not for sale, just in case anything goes wrong with the Hamann diffuser.

 

owen, when are you going to show this to me at school? are you busy @ 12?
