ABSTRACT:
A connection assembly for an exhaust extraction system which is designed to vent the exhaust from a vehicle tail pipe includes, in combination, three primary components. One component is an annular sleeve which is constructed and arranged to assemble onto the vehicle exhaust pipe. Next, there is a nozzle locator ring which slides onto the annular sleeve such that one end of the sleeve extends beyond one side of the nozzle locator ring and the opposite end of the sleeve extends beyond the opposite side of the nozzle locator ring. The third component is an exhaust nozzle assembly which includes a generally cylindrical nozzle and a pair of magnet packs located circumferentially 180 degrees apart. An extension sleeve inserted into the annular sleeve includes a series of baffles to deflect and direct vehicle exhaust.
