First time question here: For various reasons I ended up going with a 2014 E350 Luxury model, not the sport. The one thing that's always bothered me is that there's no rear diffuser/exhaust tips on this version. It looks unfinished, it's always bothered me and I've been thinking about ways to mod it (in an OEM part kind of way). I've noticed the European E sedans have exactly what I'm looking for but I can't get international parts via my local MB dealer. I've located a few workable options on EBay and AliExpress but I'd rather buy domestically and not pay an $150 to ship from China and wait a month.
Would the diffuser/exhaust tips from an E350 station wagon work? What about the rear diffuser from a 2015 C300?

I'm ultimately looking to get here:




Thanks in advance for the help
