2013 GT500 Stock Exhaust Vs. 3” Offroad X-Pipe Comparison

  • Oct 30, 2013

As mentioned in our teaser video the stock exhaust on our 2013 GT500 sounds awesome. However once we added the Lethal Performance 3" offroad pipe into the mix it made the car sounds insane. It's definitely a night and day difference. No dyno testing has been done yet however we believe we'll see gains around 20rwhp. As soon as we verify that we'll be sure to let everyone know.
