M-Performance exhaust makes it sound a whole lot better - I ordered my F30 with that as a port-installed option along with gloss black grilles.
The N55 in your 435 has a slightly different configuration than your previous 135 - the DME is different even than my 2013 335i. The MPPK software update allows for better exhaust sound and the "blip" on upshift - the 8AT sounds a lot like the DCT.
