I dented my stock header and haven't had any luck fixing it so I was thinking about getting the GYTR stainless header and muffler. As long as I need a new header may as well spend a little more and get one that will give me a little gain. I already have the PMB insert and if it wasn't for denting the stock header, I'd just stay where I am. The dent isn't huge and I'll probably ride it for a while anyway. I suppose a jetting change would be in order with the GYTR pipe change??
