Definitely sounds better that the OEM exhaust. Deep grumble on a cold start. Nice throaty sound when you give it some gas. Sounds like a truck should sound. Sounds like Freedom and Bald eagles!!! 'MERICA!!!

Easy to install and sounds great!

First off I got a great deal on this exhaust and I was a little worried when I got my package because it was open on some ends but all the parts were there. The install took me about 2 hours start to finish and was easy to install and looks great! The sound is a little quite when your crusing around but once you get on it it sound great! The instruction say to cut just behind your stock muffler to get it off but I was able to take it off all in one shot.
