Could somebody kindly advise what is the absolute minimum exhaust pipe inside diameter for the WrenSS?

Very high gas velocity on a Super Sport, certainly not less than 61mm, unless someone knows better of course

Our jetpipes are 61mm diameter (inside the bellmouth) which then tapers to about 70mm. Gap between engine exhaust and bellmouth should be 30mm. We wouldn't recommend anything smaller.

Because of the smaller exhaust specs, the WrenSS will be about the only engine that will fit.

Why is the CG usually set with gear down and UAT full?
