I went through Active Auto Werks and then went back to my custom electronic controlled system which uses the oem muffler. I can go from loud to stock in 5 seconds. You can also dial in how much sound you want. Why live with drone when you can spend 500 on this set up and have the best of both worlds? Ellwood the pug says why live with a loud exhaust when you have choices!
