Hi guys, I drive a 2017 330e and would really love it to be louder, I've been looking a few different options but don't really know what effects the mod could have on the car.

I've been considering just having the rear muffler removed but I'm a little worried this will make the car drone when driving on a motorway, and/or cause some ECU issues as ive seen people say full muffler deletes can cause newer cars to go into 'limp home mode'. has anybody had this mod done and are they pleased with results they got?

or would it be a better option to get a axle back aftermarket system replacing the rear muffler for a more free flowing one to allow more noise but still having a rear muffler on the car?

Thanks for any advise :)
