Update on mine....

...I bought some Circuit Weeks secondary cat delete pipes from an inmate here and they, combined with the FVD muffler are street exhaust heaven.

The secondary cat delete made the exhaust QUIETER inside, yet LOUDER outside, and completely eliminated the drone. There was still a very faint drone with the FVD. It is now completely eliminated.

BUT, when you get on the throttle, it sounds awesome.
