We first developped this exhaust for the 3.0d, the petrol version should have a different look. For the sound level, we have some noisy exhaust for example for Ferrari but for this car we choose to make something not too noisy because it is not the philosophy.

Is there going to be distributor in the USA for this exhaust?

Im french official dealer but as actualy we have not got USA distributor for BMW, I can take care of you.
You can verify Im official dealer on Quicksilver Exhaust website.(My logo is in ferrari maserati dealers)
