New to the forum, and any and all help would be greatly appreciated. I'm looking for advice/tips/tricks/lessons learned on replacing the stock M-Sport diffuser on the 2014 550i when upgrading the exhaust to quad tips (likely, Dinan for warranty reasons). I'm looking for either the M5 style OEM diffuser, or something similar to the Vorsteiner diffuser (fins), but would like the option of a body color match on the diffuser instead of the carbon fiber look.
I've read a lot of threads on this topic, but am not finding definitive advice on this that doesn't entail a lot of butchering on either the diffuser or exhaust.
I'm hoping to get some advice from someone with first hand experience on what worked best.
Thanks.
