I did notice a difference. It feels like I've gained some HP. Not a huge amount. Maybe 10-15 if I had to guess. The biggest difference is in sound. It's definitely louder but since I kept the stock muffler it's not so loud as to upset the neighbors. It sounds great (when my muffler isn't acting up) around 3K rpms in 2nd and 3rd. So far I am very satisfied with the NHP headers and pipes.

My new muffler is out for delivery!!!
