1) Make sure that you DID NOT use the stock metal crush ring from the stock catalytic converters.

2) Make sure the two mating surfaces are clean.

3) The bolt holes on our gaskets are slightly over sized to the stock studs and bolts so our hardware can fit through it. When you tighten everything down make sure the gaskets are not cocked one way or another and that any excess that might peek out between the two flanges is even all the way around.

4) Last but not least, no dig at the Berks but make sure the flanges are not warped.

If you have any questions at all, please do not hesitate to call me directly at the shop.

Thanks, Tony
