    Rob Gregory, the owner of Gregory Polaris in Little Rock, one of the larger Indian dealers in the country, has been working with Tab, a smaller performance exhaust company, in the development of a crossover pipe that removes the catalytic converter and adds power! The final prototype before production has been run and they are ready to take orders. The gain is 6-7 HP (!) and 3-4 ft-lbs of torque! Because of the assistance Gregory Polaris has provided they have an 8 week exclusive and are offering the pipe for $400. After the exclusive the cost is estimated to be $475 or higher. Gregory worked with Tab on several prototypes to make it extremely easy for installation and proper fit using existing hardware and the existing donut gasket. If interested call Gregory Polaris at: 501-834-0344.

    The installation at Gregory polaris costs $120. but I 've been told that riders could do it in their garage with very few tools needed. Again, the benefits, as related to me, are as follows:
    • It gets rid of the catalytic converter and the excessive choke down of the challenger engine.
    • It yields a 6-7 HP gain and a 3-4 ft-lbs. of torque increase if using stock slip ons.

    Does anyone have any dyno results with the Tab Crossover pipe that are already utilizing the OEM Indian Stage-1 intake, exhaust and ECM reflash kit? Any news on OEM Stage II (cam upgrades) and Stage III (big bore kits) for the Challenger?
