I can sell you a 328 BMW that will pass sound. Anything else with the sport exhaust option and you are hosed without the lift and left lane technique

Like Max and Mooty say you need a GPS magic box and a set of turn down pipes for 90db days and GPS box only for 92db days.

We have cars running SW muffler bypass and with GPS box pass 92db. So it works!
