Your choice of larger diameter combined with richer mixtureseams to be a foolproof combination.Any mod I've tried from Kerker exhaust to any abrupt diameter reduction transition has resulted in a total dead flat spot in rev building,back pressure waves I understand.Its sure fun to experiment when you have the tools and talent to use them.
