they can be a little rattly, and are not as smooth sounding as the 2.5/2.8, but I expect that's because of a more generous valve clearance I expect. But they sound a hell of a lot better than the 2.5's/2.8's when reaching their 7k limit, drop the rear windows, and give it some welly.........lovely. Also the M3 sounds nicer when you start to just pull away, deeper sounding, than the smoother creamy 325's etc
The exhaust is double skinned, so even if the outer layer is corroding, the inner should still be sound.
I've been driving a 328 every now and again, and got back into the M3 after a few days, and really notice the difference when driving, it's far better.
Hows it going though Mike, still like it?
