How are you tightening the flange bolts...?? Should be:
- Tighten top nut of front cyl flange 9-18 in/lb
- Tighten bottom nut of front cyl flange 100-120 in/lb
- Final tighten on top nut 100-120 in/lb
- Tighten bottom nut of rear cyl flange 9-18 in/lb
- Tighten top nut of rear cyl flange 100-120 in/lb
- Final tighten bottom on bottom nut 100-120 in/lb
Re-check bolts to ensure 100-120 in/lb after 50-mile run (cool bike).

iceman : i am using the correct sequence but is that supposed to be in.lbs. or ft.lbs. because i guess its possible i maybe over tightening if thats possible. think over tightening would cause a leak ????
Never heard of any issues regarding choking the exhasut, they don't block the port.

inch pounds, 120 ft lbs would probably cause some real damage, maybe even break the studs. It is possible to overtighten them. I've installed many many sets of V&H pipes including Propipes but never had a leakage problem when using new gaskets.
