All you ever thought about DRAG PIPES
When you add more inch and increase power by 50% the exhaust
gases build up pressure in the pipe as RPM increases and affects the overlap process as well as the O2 sensor that sees the gases as being rich so it wants to lean the engine out but keeps leaning out the engine thru the mid range and the engine will not preform like it should. So it becomes un tuneable
. Also most dual drag pipes that are located on the left end right side of the bike are two different lengths which make a unbalance exhaust system- and then you add baffles ( like putting in a cork ) and that create more back up in the pipe-the gases just cannot get thru the system - so stay away at all cost from Drag style pipes when increasing power with cam, compression and more cubic inch's -
Buy a reliable two into one exhaust system and you will be happy.
