It looks like Sportwagen Eckert sells a rear bumper without the exhaust cutout (https://sportwagen-eckert.com/produc...69-----73.html), and I was wondering whether anyone has firsthand experience with their bumpers.

I found a thread from a couple years ago saying their customer service and perhaps parts quality had gone downhill, but given the age of the thread, perhaps something has changed for the better since then? Thanks for your help!
