I recently purchased a 2010 BMW 550i and I have been trying to decide if I should make some modifications to the exhaust. I really do wish it had a louder rumble but not to the point where it sounds embarrassing and not for it to be heard inside of the car.

The last couple of days I spent watching youtube videos and trying to decide which sound I like the best. The delete exhaust doesn't sound too bad but would love to hear it in person. I was also considering getting the M5 bumper so I can change it to a double exhaust. I really like the look of the double exhaust!

Those with 550's do you advise or things you would have done different knowing what you know now? If anyone is NY that has a modified exhaust I would love to hear it.

Thanks in advanced.
