to my surprise, i just received my brand new White Brose E series complete for my 400ex. i installed it and it sounds great! however, there is a dent on the inside of the muffler. can anyone tell me if they have this dent also? here is a picture of it.Dented WB E Series

 

Nick,

WB puts that dent in the pipe so that it won't hit your rear caliper when you bottom it out landing a huge 125' double. My dad runs one of their slip on's and it has the same thing on it.

Later,

Dennis

 

yea, there was a thread earlier abut ths and its for the caliper
