    IMO downgrading in pipe diameter will cause a restriction.

    too big a pipe can hurt you the same as too small a pipe.

    if you have a 1 inch pipe you will be trying to cram all that hot gas out a itty bitty pipe.

    3 inch is more than enough unless your trying to get in the 10-11's

    with each exhaust stroke your piston is pushing all the air out of your cylinder and exhaust. if its say 8 inch diameter, the hot not so dense gasses will have time to cool and become cooler more dense gas, so you will be pushing more weight from the cooler heavier gas out robbing power.
