mod done. quick and easy. Still detect drone between 1800 to 2200 rpm , above that all has been eliminated. great fix. Driving the car above 2200 rpm simulates stock sound. Thanks for the info. Next off to xpipe or test pipes. I asked if the muffler shop can produce a test pipe eliminating front cats, but was rejected due to emmisions clause. They are not allowed to remove cats due to emmision requirement.
