no i'm saying they have some aftermarket headers, not sure what brand...they looked stainless...dropped down just under the fairing and that was it....loud as hell....they basically just removed the pipe that leads to the cans as well as removing the cans...just a header and thats all....now is that damaging to the engine? i have always heard yes...but some say no...just looking for evidence and proof in some way shape or form....sorry for the confusion...
