70mm would be an uncommon size, doubt you'd find one of the cheap pipe kits in that size.
Use either 63mm ( 2.5" ) or 76mm ( 3" )
2.5" will support a lot of power, so unless there is a huge amount of bends or you're beyond 5-600hp....not really much point using larger.
Just use one of the hose clamps nipped around the alloy for a marker, then cut either with hacksaw or thin disc in an angle grinder.
Use a flap wheel in a grinder to remove any excess or trim down so the cut is true.
Flap wheels are great at removing metal, so go easy.
