Hey scott!
It's time for you to have some home work done.
Take few hours & go google to look @ customer's review on every single bran,plus you can use youtube to see/listen to videos about mufflers
All muffler brands offers products suitable for our toys and the rest is up to you choosing the right one.
Go to the shop & explain them what are you looking for,something very similar to the OEM muffler which will not cause any huge difference on the VX's driving performance & not cause any disturbance to the neighbor.
