He's right, there are so many systems out there today. You could go directly on to their web site, most have recorded their systems so you can hear what they sound like before you buy. Myself, I've always liked the sound of either Basani, or Magnaflow. But to each his own. My BOSS 302, has Hooker headers connected to a Basani X pipe, and Basani mufflers and tail pipes, which sounds like no Mustang you've ever heard. Awesome, but again it's far from stock. Check around, and see what it is that YOU LIKE, and take it from there, Mike D. Good luck, I hope you find what you like the sound of. ( ITLRUN )
