    GS450TX Mac 2 into 1 Exhaust ...Need to Rejet

    Is it necessary to rejet the carbs after installing a MAC 2 into 1 Exhaust on my 81 GS450TX motorcycle. I searched for this but couldn't find anything. Thanks for your attention.

    All depends how restrictive it is.

    Run it for a bit and do some plug chops to see how the plugs look... there are some details on BassCliff's site for this I believe.
