I've noticed from a few mags (Eurotuner) have mentioned that a number of vw used Supersprint as their choice of exhaust. In the last Eurotuner alone, 3 of them had the supersprint cat back system.
Why do you think these big name tuners decided to use supersprint as oppose to Remus, Magnaflow, or even techtonics... or any other systems.
Just curious. I haven't seen any dyno's except for TT.
