I was looking at the "Sideburner" too,but after seeing the 2 page ad in Hot Bike and the way they're built I've changed my mind. I think they are one of the best looking pipes out there but there is just too many layers (don't like fake stuff) of pipe and not knowing what they sound like....well??? donno. Not being able to change the sound and/or muffler........... I'm looking elsewhere!
