Ok i got a few clips of me turning the car on, driving easy, and a quick heavy acceleration. Did not get the Silent MDS cruise yet or a high speed cruise or high speed/rpm sound. Let me upload thru tinypic brb

I have a 07 Charger RT. Does anyone know if you can make the existing stock exhaust louder (have more growl or rumble) without having to go out and buy a new exhaust? I know it may sound strange, but I'm new to this so I don't want to spend if I don't have to. I just want the sound. Thanks
