i currently have a magnaflow exhaust on my 03 mach 1. I need something that sounds deeper and more aggressive. I have narrowed the list down to three. I want the one that sounds the most aggressive but also doesn't sound like a motorcycle. i want the muscle roar. I am stuck between the MagnaPack, Borla Stinger, and MAC exhausts. I really dont know which one to get, i need help/insight.
