Hi Paul

The tuned length is 1064mm as it's my old Taffspeed Mk3 exhaust system!
I still have all the workings out that Terry & myself did with Jim Lomas when he was in Attleborough Norfolk, circa 1988!
It was developed to work best with 180' exhaust timing on cast iron cylinders & 190' on TS1 225 setups.

Hope this has helped you.
