Question FLOWMASTER SUPER 40 WITH 3.7 MOTOR

This is a long shot but I have to ask, has anyone ran the Flowmaster Super 40's on a 3.7?
I'm in CA so I cant remove resonators or cats, just input on the mufflers and stock dual exhaust.
Ive listened to multiple sound clips and Im concerned about the interior noise level and the annoying gurgle when reved high or downshifting.
They sounded the best among the 40 series to me without the rice rasp but I thought I'd ask here?
Thanks guys

If you are worried about noise Flowmaster of any kind is not what you are looking for. My Exhaust is CARB legal with BBK Short tube headers, FRPP True X and Borla touring. Catalytic are stock and in the stock location. Here is a Video off the back of my car so do not mind the wind. While you are looking for Mufflers, make sure they are 50 state legal and not just 49, California has had a 95DB law since 1998 and it is a fine and not a fix it ticket.

Your car sounds great! Ya, I cant do headers here either. Not sure if the super 40's are over 95DB :-/

Actually the BBK Short Tubes are legal in California since you do not have to modify the Emissions.
Emissions Information
This part is C.A.R.B Approved. EO Number Is D-245-16
It is Legal For use on the following applications in ALL 50 States: 2011-2014 Ford Mustang V6 3.7L ONLY
