The S55 is a powerplant that is quite challenging to work with in terms of exhaust notes. It's safe to say this car doesn't have the most inspiring exhaust note. However, this Dinan setup sounds pretty darn good for an S55 powered vehicle and enables a deep, aggressive growl that all M4's should have from the factory. And the best part is that it's a valved system so it can be quiet or loud with the push of a button.
