I've used rubber before, much further away from the manifold then that (had a 6" long steel pipe off the flange) and it still managed to get brittle and crack causing leakage.
On my current setup I've got Earls prolite line with the flameguard covering. I've already managed to make a royal mess of it due to locking the timing and forgetting to unlock it (ie, antilag more or less, constantly). The house is about 1" from the manifold COLLECTOR. Moves away, just where the fitting screws onto the drain flange is the issue. The flameguard has already started to deteriorate. First real power pushing session will be on the dyno, and I'll watch it closely (with a fire extinguisher at hand)
