Hello to the TM community.
We measured the ground clearance on a Plus Six with the original hainholz resonator.
From the floor to the pipe in front of the silencer, there are approx. 90mm for both exhaust systems.
The lowest point in the original exhaust system is the Hainholz resonator. There the ground clearance is 90mm. Our silencer has a ground clearance of 95mm there. The pipes behind the silencer have a ground clearance of 100mm on our exhaust. Of course, the original exhaust has more because the four small pipes have a much smaller diameter. It also has to be said that the pipe in front of the silencer has a diameter of 80mm with us and originally it was 76mm. I can't say anything about the ground clearance of the Morgan sport exhaust system without Hainholz resonator, because we don't have a vehicle with us that has this exhaust fitted.
So you don't really get ground clearance, but fun :-)
