ds650 header
#2
The stock pipe is a full blown header pipe, its just that the end cap on the muffler is restricting it from performing to its max. That is why they came out with the end cap because MR.HP has dyno proven that the end cap will produce more horsepower then any slip on. So i am sure if u get a header pipe u wont be able to tell much difference in power since the stocker is a full blown header pipe. You might be able to tell alittle on top end but probably none on bottom.IMO[img]i/expressions/face-icon-small-smile.gif[/img]Lance
