The other solution is wrapping, which in my case really helped not cooking my pants or legs.
I used Thermo Tec heat wrap with the ceramic coating spray, 45' total and one whole can.
There is so little heat now that I can actually adjust my idle bare handed in the middle of a ride.
The con is that all the heat is now in the exhaust area, which means I might add a shield in this area, but it is not necessary.
