Well I have had the Magnaflow for a year now so I don't know about it gettin louder but I don't know. I liked it before but having my rear bumper damaged is drivin me crazy so I'm going to get that replaced quick and won't have exhaust cut outs so really my only option.
It sounds about the same just deeper and drones more. I don't mind the drone though. It's not bed enough where you have to yell or listen to your stereo louder than normal.
