I got a set from an E90, to make it work the exhaust shop had to cut the flanges off the bottom part that connects to the exhaust and weld new flanges at the correct angle else it definitely doesn't fit.

with regards to after market downpipes I don't like them, I had them for a while on my previous E89 and they ruined the engine mount because they simply sit to close to the thing! They get extremely hot and over time they cook the engine mount. Instead what I did was got myself the stock set of E90 downpipes, gutted them and fitted those instead, the power difference was pretty much non existent but now O2 sensors are a breeze to get in and out from the top with a shorty spanner and there are no issues with the engine mount getting cooked.
