Thought I remembered correctly, so I still have a bit of a problem.
But all the bits I bought including two cats with the exhaust box was the same as MB wanted for the control panel alone !
A M G rear box is dissapointingly quiet, perhaps even quieter than the standard,
although it seems to be more responsive.
Has anyone tried it with the silencer/muffler behind the back box removed ?
Or would this upset the backpressure?
