Hi c_creations, hello all,

Two pipes will reduce backpressure and will probably call for a small enrichment of your fuel mixture, which will result in a slight gain in power, throttle response, and fuel economy.
In your case an "X" pipe will be no improvement over the "H" pipe, which will only quiet the exhaust.
