Audi R8 gen 1 exhaust valve disconnect mod

Love the car, could be a bit louder though. This mod was one I read about on the R8talk forum and I’ve created this to spell out the work and results that I had. Use this at your own risk!
I found the modification works better for 2nd-3rd gear between 3-5K revs. It’s not something that changes it that dramatically to make you think you have a sports exhaust but is something that puts a slightly lower tone in for free.....
