Love the sound of the exhaust at startup. Read about the vacuum workaround but don't think it exists on my 550. Any other suggestions. Not looking to spend a ton of money if there is something on the lower end that I can dabble in. Thanks.

RPI exhaust. There is no substitute

+1 on RPI- Sounds very refined but agressive. Dinan sounds great, too, if you have the coin. There are some used E60 systems on the list every now and then- I may try to snag one of those...
