Just confirmed with the owner of Thermal R&D today, that i will be dropping my ST off on the 25th for a Design, build and market for a new addition to the Explorer ST exhaust market. Im not sure Whoosh is part of it, but im assuming it is since Whoosh got me in contact with Thermal R&D.
im confident they are going to make a better sounding system than Borla. Borla sounds real raspy to me.
