I checked out their website at http://www.spintechmufflers.com... and although the testimonials from racers (drag, roundy-round, & road racers) looks good, their technical explanation and graphics don't provide enough details for me. Anyone have any insights on this? Their "Pro Street" model is very compact... 4x6x12 ! Or, am I the only Vortexer who surfs muscle car sites to get ideas?
