can you burn up an exhaust valve if you are running an open pipe? (as in no muffler) someone said something about that today, i know you can run an open header on cars and not burn up your valves i just didnt know if it was different with a bike, if it matters i have a 2000 zx6-r.
i know you are supposed to get it tuned after you change the exhaust, but i am going to have a custom pipe made with fewer baffles in it. im still running the exhaust i just dont have the muffler on it. I am going to be taking it down to him so he can make his measurements, and it is kind of a far ride. i didnt think it would do anything to the valves.
