My company, Scorpion Motorsports, manufactures the Scorpion P6. We currently use an off-the-shelf exhaust headder with a built in catalyst. We believe the catalyst used to be one of your units, model number: SSQ1-750000-02. The vehicle uses a 600cc sport motorcycle engine. If you believe this to be the wrong part number please advise on an appropriate part number. We manufacture only 40 vehicles per year, but I would be interested in finding out what the price of these units would be and what your minimum quantity would be. Thank you,
