These pipes claim that they are made with something called slt or sound lowering technology. I can't find any clips anywhere and wondering if they are louder than my stock m50 pipes.
I believe that the Roadburners are made by HK. From what I understand there is a dispute between HK and Parts Unlimited. HK wants to use another vendor but PU balked at it so HK came up with Roadburners so they can use another vendor. You probably won't find any sound clips since they are new to the market pipes. I would imagine that they are exact duplicates of HK pipes.
Big sale here on Roadburner pipes. Pipes for your bike here. KA-CHING.:mrgreen:
