I have the Fabspeed valved side muffler deletes and their center delete.

With the valves closed it sounds a tad louder than factory from the outside, on the inside it's definitely louder, but my wife has never complained, the Bose still sounds fine and zero drone at hwy speeds so I'm a fan.

When you have the valves open it's amazing, like Cup Car-light , but not obnoxious , has that "tuned" sound I prefer .

I did the Soul side muffler bypass, then I did the fab speed center muffler bypass. For daily driving (and for sound limited tracks), I put the stock center back. Both the side and center bypass just "feels" faster! and the sound is amazing.

Just added the valved side pipes to Bbi valved center. Sound is much better to me especially when you step on it at 2000+ rpm. Valves do work a little….enough to not set off car alarms in my condo garage. I don’t know what a drone sounds like so I couldn’t tell you. Car feels quicker. At lower rpm’s it’s not too loud, so it’s controllable.
