    Hi Glen,

    You can most certainly attach an expansion chamber to the Mod-50 style exhaust system (contact Anthony McCulloch elsewhere on this site). Whether it works or not is another question.

    The modified Nydahl system patterened will sell for $495 USD + shipping but will not bolt to your Tohatsu - It's for the OMC 49.9 loop triple only.

    To be honest, the Tohatsu triple has a near copy of the OMC Mod-50 pulse tuned exhaust system already. You'll go through alot of effort and expense to improve upon it without significant weight gain.

    If you want more than incremental gains, you should consider N2O or a turbo Good luck!

    Are these exhaust systems still available ? Do anyone know if they can be purchased somewhere?

    New or used not a big deal for me, if you want to sell your used send me a PM

    Bad news: Regarding the modified Nydahl "laker" exhaust, no deposits were received, so I'm scrapping the project except for my own engines. If I get bored next winter, a few may be built and offered.

    For now, it's back to the shop where six customer towers, six exhaust systems, a NBRA 49.9 and 49.9 OMC turbo are in construction.

    Enjoy your 2012 season!

    Hello Stephen,

    Thank you for your inquiry. There's a potential customer for the prototype, making a decision Saturday. If his purchase falls through, you can purchase it and make copies in Aussie. Est cost delivered is $625 USD (not including tax/tariff if any). I'll respond with an update next week.

    Hello Mumat, A check has been sent for the prototype. Once received it's gone, no more will be produced. Apologies, but there's just not enough market to justify the expense for patterns. If you know a good CNC mill guy, just take the photos and he can make them from scratch. Good luck!
