Dsb, I am sorry for the late response as its been a while since I have found a wifi spot here in south of italy were I am touring.
The SuperSprint x pipe's are magnificent,since I was mixing and matching products from different tuners I thought I would have some drone assuming the lower rpms; however that doesnt seem to be a problem.
When I got it installed in march it is obviously louder and more free flowing which is good and since it doesnt drone it seems to be as comfortable as driving a stock slk55. It gets louder once you nail it however in traffic or inner city congestion or slower speeds its perfectly fine.
I hope I've helped in contributing with my experience and good luck with your final decision whether to de-res or to have the oem resonator.
