I am purchasing a used roush axle back exhaust in a couple days but was wondering what are the difference between the 5.0 kit and the v6 version so I know what to look for. The guy sold his car and I want to make sure I'm buying a proper part.
The v8 axle backs have larger pipes. They're 2.75" in diamater where the v6 pipes are either 2.25" or 2.5". I'm not exactly sure. But if the piping that connects to your over the axle pipes is 2.75" in diameter its the v8 axle backs
