I have not picked or driven my 1m yet, but having built several cars. O I have had a M3 that droned with one exhaust but had no drone with an aa exhaust. I have a 400+ hp 335 with a dinan exhaust that does not drone and is not that loud.

So, if there is a drone, someone will make an exhaust that does not and who here does not plan to put at least a cat back exhaust on this car?

A tune+cat back back + cai will probably get this car is the 400hp range at the crank.
