I am hoping to get some advice here, I have 2002 R6, and I recently purchased a K&N air filter and a D&D Slip on exhuast. The filter is brand new while the exhaust is used purchased on Ebay. My problem is noise and power. The exhaust was previously damaged with minor sctraches, but overall looks okay. 2 things i noticed the exhaust is extremely loud, and I feel like I lost power.
I am just wondering if this exhaust could be possibly damaged internally, or is this exhuast not a quality product. I was thinking of buying a brand new D&D but I would hate for the same power and noise issue. Have anyone had experience with this type of slip on?
Or maybe recommendations on another product that is reasonibly priced.
thanks
