Would Tom Hand have any information in this regard?

Lloyd, The only 'real world' comparison I have is with my RAIV Judge. It had an old Maramount (sp?) system (kink-bent 2 1/4" with 20" case 'turbo' style mufflers) and with the original motor ran 13.70's at 103 mph average. I swapped in a Torq-Tech 2 1/2" mandrel bent system with 18" long DynoMax UltraFlo mufflers and the performance improved to 13.50's at 106 mph. I'm sure there is more potential gains and it has run 12.80's at 110 mph with the replacement RAIV engine (borrowed from another RAIV GTO) with the same exhaust system.
I believe there is at least a 10-15 RWHP reduction going from DynoMax UltraFlo's to the SuperTurbo's, and another 10-15 hp reduction going to the factory (Waldron/Gardner) mufflers.
It would be an interesting test.
