Verdict so far - sounds better but not significantly louder. What is definitely noticeable is the dsg farts, which a can now hear with the window closed (up TIL now I have had to stick my head out of the window, and I’d only notice them in 1st and 2nd hear, as the wind noise would drown out anything else. Token photos included.
No obvious drone either, although I haven’t really done much more than my 15 mile commute. The roads are bad enough, and the Michelin’s noisy enough, such that all I could hear was the usual road noise.
One thing that I did notice, however, which may spawn a new thread, is that there seems to be something odd about my passenger-side exhaust outlet. I have noticed for a while that the other one has significantly more carbon deposits that the letter most one. Initially I thought this might be due to some valve system in the exhaust that would shut one off at low lod (like the system my old 335i had). However, after looking at the exhaust today when I returned home I noticed a couple of things. Firstly then right exhaust was very hot - this may be normal, I can’t recall the last time I bothered to inspect the exhaust after a drive, but the second thing was that the left exhaust was making a funny sound, and not much was coming out. After looking down the pipe I noticed something that looked like a hairball stuck down it.
Is this an indication that the muffler could have problems?
