Increase diesel active exhaust tone

Having had my oil burner for a few months, was curious if there was a way to further increase the volume of the exhaust actuators to give a deeper sound in sport mode?

As far as I know the actuators are mechanical flaps that open up so the only way to modify the noise further would be to fit an aftermarket exhaust or mechanically modify the existing one. On the M3 forum there's a popular mod where some folk have had material removed from the back is and the welded it back up.

Diesel Maseraties use Eberspacher ActiveSilence/ActiveSound technology which is Active Noise Cancellation. It is absolutelly electronic and uses microphone to measure the noice and loud speaker and then cancel it by playing it in antiphase. In addition it is possible to add any desired sound to produce it from the exhaust system. So actually the exhaust for Diesels is straight pipes after cats with microphones and loud speakers connected in the end of the pipes to cancel the noise and add the right sound.

So any modification is electronic and I saw some electronic upgrades for exhaust sound of Diesel Maseraties on the market, but never tried because satisfied with what I have from the factory.

Wow! Didn't know that. I thought it was the same as the petrol. So did the dealer!

Thanks for the info.

Because of some interest to this subject I spent couple of minutes to remember the tune for sound of Diesel exhaust. Here it is:

Sound Booster Pro Active Sound Maserati Ghibli Diesel-40595

Once again. I never tried it and do not know anybody who did it. However it theory it should work. What I'm worry is the sound map in this tune. I know that Maserati reproduces the sound of exhaust of its V8 and that is why diesel owners love it so much. Iím not sure that the independent tune company is legally allowed to use the same sound.

Harley Davidson Motorcycles tried to patent a sound of an engine years ago and it could pass.
