Sounds like a blast to drive! How is the smell?

Not bad with the windows up. Windows down there's def an odor. To be honest, it's a bit stronger with the X5 compared to my old catless E46 M3. Would prob detour some but not me. Wife hasn't noticed yet, thank God! She doesn't know about the downpipe

FYI, BM3 flash tune allows you to customize some features including "start up roar" which I'm loving. No matter how warm the car is it's a cold start every time. The standard BM3 stage 2 tune defaults to disable cold start since cats are deleted. I personally love the sound of cold start.

Gotcha. Yeah I don't have that. Something does rattle sometimes within the first 100 yds when I pull out of my driveway after a cold start. Goes away after the first gear shift. Come to think of it. I haven't heard it since the downpipe install.
