  • Straight through pipes

    G’day all,

    Just recently put some L.A Chopper straight through pipes onto my 1999 R* . My question is, because the pipes are straight through without baffles, will either the back pressure (or lack thereof) cause any long term engine damage?

    Jetted properly it probably won't cause damage but you will loose a lot of performance and will likely get decell popping that will not be curable.

        Remove the AIS if you have’t already to eliminate most of the decel popping.

          Your bike will loose some of the low end torque.

            If you're unhappy with the loss of low end torque, you can add some baffles that won't effect sound but help with back pressure:

              I’ve always run straight pipes. No issues with both carb and fuel inj bikes.

              Ive compared straight pipe to same pipes with baffles in. Power loss on low end is so little you won’t notice.

              Decel popping is something some people don’t mind and some people hate. If you hate it, do AIS removal. If you don’t mind it, still do AIS removal hahah
