A friend of mine wanted to hear a sound clip of my car so I recorded a cpl short ones. I am currently running Mac axle backs with an o/r h pipe on a 2010. Like many, the sound clips do no justice and sound better in person. The Mac's are very deep and get some rasp at 2500 rpm, overall I am very happy with the sound but it is pretty loud. I know this may not be everyones cup of tea but I wanted to share in case someone is considering this setup. Thanks!
