Great Pipe
By L. Arry Austin
First of all, I'm impressed with the fast shipping.This pipe made my 2001 XR400R come alive without rejetting.I just followed the directions and was easy to install. This pipe calls forstock jet settings and remove the snorkle. I haven't removed the snorkle yetbecause I feel no need too. Great power gain and a nice sound too. The sound is not to loud but loud enough to make your bike run and sound like a whole new bike. A little louder than stock but with power core 4 sound. Good for neighbers and me as well. The sound is just what I was looking for.There was a little play between header and this pipe during installation but high temp silicon worked that problem out. Directions even says to apply it too. So make sure to have some. I had to make a quick trip to auto store to buy some @ $7.00.This was the cheapest place I could find a decent deal on a slip on pipe for my bike. I'm 41 years old and probily have this bike untill I get to old to kick it. It gets me through the woods to look for them great mushroom patches and chase the hounds while hunting. Powercore 4 is a good performance upgrade and will help get you up a hill climb. Thanks again for the great deal and fast shipping.
