All I can tell you is DON'T buy the Edelbrock shorty's. They do not stand behind them if the welds don't hold and they (the welds) won't if you are supercharging. I know of two other H2's here locally that have had the welds crack in the collector on the drivers side and Edelbrock won't do anything to remedy the problem.  I am going to the Borla, at least they have a million mile warranty.
