Yes, from what was sent to me, there is a great deal of drone from the Roe and similar clamping issues, and based on the fact that they use Borla mufflers for the integral part of their exhaust, I would say that the Borla would do the same thing. The search is narrowing. For me it is now between the Corsa Track (again), and the Belangers (which I have not heard). I had B&B on my GTS and was never happy with it, the Mopar race will probably cause more trouble than its worth (going catless), the Mopar street will probably not be much of an improvement over stock, and the Roe and Borla will have more drone than I want. It would be nice to have all of them available to hear.
