Exhaust weight savings

[jrevens]

My 912 model I has dual exhaust. I installed 2 Volkswagen mufflers for weight savings. In the photo they look like exhaust pipes, but they are actually two Volkswagen mufflers siting side by side.

How did you pipe those Steve... a simple 2 into 1 on each side? Can you make any kind of comparison noise-level wise to the Rotax muffler?

By the way, that's a beautiful picture!
