Video's below - the 'cold start' video was actually done afterwards (you'll notice the car was somewhat cleaner...!)
Cold start (haven't cropped it, and I wandered off for a while -
- so, skip to ~2:10 once bored for light revs):
'second' video with engine warm (this is after a ~250mile drive) - 0- 45 secs in Comfort mode, 47 sec - 1:20 in Sport, 1:21 to 1:29 in Eco Pro, then two more revs in Comfort, two in Sport:
I didn't notice until watching this how much it burbles in 'comfort' - can't normally hear it from the cabin, unlike 'sport'.
Overall I'm very happy with the exhaust, I noticed straight away the difference to stock and I've still not done the ideal '1000 miles' for it to bed in. As far as 339 vs 340, only way to tell for sure would be to film two cars at the same time, can't see how that is going to happen
