    Let us know how it turns out. I thought a loss of backpressure would actually hurt these engines?

    Backpressure is caused by the muffler, cat, and restrictive headers. Backpressure induced by the x-pipe will be very minimal, but it will maintain/increase scavanging.

    On a modern engine, any back pressure is bad. What hurts engine performance and efficiency is screwing with the scavenging ability.
