I thought the earlier 535 models had 3.5" piping, no?

I just grabbed it from ER's website: http://evolutionracewerks.com/node/240

Maybe 3.5 stock but would fit 4" as long as it tapers to the correct diameter in the end? I'm not entirely sure.

How did you like the performance with this? I'm in CA so need something that can easily come on and off.

Significant difference and sound, love it! If you have access to a lift the install/uninstall is easy in my opinion.

All, this is the SHORT version, capable of fitting 2011 to 08/2014 535i and 640i with n55 engine. These models use a factory Pneumatic Wastegate.

This will not fit the 09/2014+ as they use use BM-EXH016 (Long version). This model has a factory Electronic Wastegate.
