Morning all

So after a 13 year hiatus.. (kids wife house etc..) i'm now back in the fold with the Z4 family & man it feels good to be home

I took delivery of a 2021 (2020 built) z4m40i this week& its by far the best car ive ever owned (black wheels, frozen grey paint & black badges, its epic)

Now we've all watched the youtube vids, pops bangs & cackles in full hooligan mode in sports +.... except mine does everything but the extra noise, any ideas???

Welcome back . Do you mean just on the M40i ? Most of the cars that pop and bang have had the ECU modified to make it pop and bang or have an aftermarket or straight through exhaust . My E86 didn`t really pop and bang until I changed the headers and exhaust .

Put the roof down

Thanks alot for this

Guess i'll be hunting down an ecu specialist then! (I still want it to be neighbour friendly but then an animal out on the open road in the right mode)

Mine is completely standard and does in sports+

I’ve been told many times it’s sounds awesome from the outside (cars behind etc) but you don’t experience that at all when driving the car.

When we were in France/Spain you could hear it all the time when going through tunnels so it is there

Thankyou!
