    Identify this exhaust? GS1000

    Seller has no idea what brand it is, and I can't tell the difference in most so maybe one of you gentlemen can help me out.

    Best guess is a MAC.
    Based on the flare of the muffler at its midpoint and the pointed bottom of the collector.

          A MAC baffle is different that that one.

            That is probably the "competition" baffle.

              Google image search for "MAC exhaust baffle" says it's a kerker it looks like.
