Howdy,
I recently purchased a 2007 VFR that came with Two Brothers mufflers and a mid-pipe. It's a 4-to-1 system but has both mufflers to preserve symmetry. The left muffle isn't used. but could be storage for tools, registration, etc.
It sounds great, but I need to swap back to the OEM mufflers to preserve my remaining hearing. It's my understanding the OEM mufflers are fairly quiet.
I'm located in Central Virginia. Send me a message if you're interested and we'll work out the details.
Thank You, Matt
