Best Weber Progressive 2 barrel

Sorry, no weber knowledge.... but..
For a cheap upgrade to make a 225 slant wake up, cut the head .100 and add the super six (2bbl intake and carb). There are 2 outlet sizes on the exhaust manifolds (that I found). Use the larger (2" ??) and run a 2 1/4 exhaust pipe off of that.

Done this twice and man what a difference.
