I got mine custom made from Stromung (didn't want their logo on the tips). Cost was $915 shipped. They are a small company and the customer service was impeccable, and the craftsmanship of their cans are superb. I couldn't be happier.

Standing at 13.8 lbs per side. 10% drone when at the wrong rpm. 73mm tips.

Couldn't agree more. Personally I love the occasional decel cracks and pops as that is the BMW Performance Exhaust sound I was looking for (OEM mfg for e9X for instance). Slight vibration and drone in the lower RPM range, but nothing bad at all. This is the first time I have ever had a car with exhaust, and it only took me one day to get used to the minimal drone (highway speed in top gear with medium throttle). I commute 50 miles highway daily and it is no issue. I am glad I didn't go for the Remus. You also have to consider the whole system, flange included, is stainless steel.
