in that case you have a few very good pipes to chose from.
ill start of with the two ive had which is a victory big bore and a Bartolone Torpedo. both are torque pipes but they still pull high very well i found the victory had slightly better top end. both pipes pull hard bottom to mid but still max out my TTO +20k rpm, the Bartolone has a much better quality and overall Finnish.
Now for a popular pipe among people wanting strong mid to high is the victory pro pipe which from what ive herd is one the few pipes that punch exceptionally well in the high and still is not a dog of the line
jet pro pipes are also high revving pipes but never tried one and not too found of them myself so maybe someone else could shed some light on it?
