Jim is right, 2, 3"-4" exhaust outlets run into a 2 1/2" single outlet is going to be more restirctive.

I think if throttling back from slalom speeds 30-36 would cause head gasket problems - more members would be reporting problems.

Correct me if I am wrong... head gasket failures are almost always due to 3 things... overheat, defect in gasket, or improper installation.
