Flowmaster describes this "mild". This easily sets off car alarms with excruciating low frequency resonance when stepping on the gas at midrange RPMs.

I am very satisfied with the Flowmaster 70 lock monster. Great sound installation very easy would recommend this type of muffin to anyone who owns a Ford pick up our SUV vehicle. Makes my Ford sport Trac sound like a very high performance vehicle.
