Is it bad to take baffle out?

Motorcycle exhaust systems are complicated designs and made to allow maximum performance from the motor. Straight pipes or "drag" pipes are made for just that, drag racing. While it probably is not bad to take out the baffle it will hurt the performance. If it is not a Harley-Davidson and one is trying to get that sound it won't work. The design of Harley V-Twin and the degree of engine rotation at which the spark plugs ignite are the source of the sound.
