Modern Vespa

So as I've mentioned in other threads I recently added a 2006 BV500 as a companion to my 2016 GTS 300 Super. I brought it home on Monday, riding 180km on the highway and I was really happy with how smooth it is and how good the Givi tall windscreen performed at 120-140km per hour.

The only thing that I felt it needed was the rumble and the sound that my GTS makes with its Remus exhaust. Now you have to understand that I am not looking to spend $700CDN on a new Remus/Akro exhaust as I feel it is overkill based on what I paid for the bike. I was just wondering what other options I have new or used that would not break the bank.
