Rep Power: 293

Ok. My gf has a V6-Mustang and awhile back she wanted more power so i said ok and I then added an Intake, MAC Exhaust and some light and bigger rims. It actually helped quite a bit. So now she is used to that power and she wants more power. I have been looking around and there is some MAC headers long tube and then you can get an offroad h-pipe without cats. Now my problem is i have never heard what that sounds like on a v6 mustang. Right now the mustang sounds like a v8 and i love it so thats why i am worried to get the headers and h pipe and then it will sound like a rice burning weed eating sounding exhaust. So what do you guys think and do you know where i can find sound clips of the MAC exhaust with the long tube headers and offroad h-pipe. Thanks
