Abstract
An exhaust extension pipe kit for replacing original equipment of different size and configuration, where the connector to which the exhaust extension pipe connects is of a ball type and the original equipment have differing ball radii, wherein the exhaust extension pipe is dimensioned to connect to the large diameter ball and an adapter is provided for connecting the smaller diameter ball which is configured as a cup-like body having an opening in the base thereof together with means for restricting the non-axial rotary movement of the adapter.
Claims13
A replacement exhaust extension pipe kit suitable for use with either a first vehicle that was originally equipped with a first tubular exhaust extension pipe having an inlet end connected to a catalytic converter, an intermediate region of predetermined first configuration, and an outlet end spaced apart from the inlet end by a first distance, or a second vehicle that was originally equipped with a second tubular exhaust extension pipe having an inlet end connected to a catalytic converter, an intermediate region of predetermined second configuration, and an outlet end spaced apart from the inlet end by a second distance, said kit comprising:
- a first tubular section having an inlet end for connecting to the catalytic converter, an intermediate portion configured to the spatial envelope of both the first and second configurations, and an outlet end spaced apart from said inlet end by a third distance;
- a second tubular section having an inlet end and an outlet end spaced apart from the inlet end by a fourth distance, said second tubular portion having an intermediate portion configured to the spatial envelope of the first and second vehicle, the fourth distance being approximately the same as the third distance and the sum of the third and fourth distances being at least as long as the larger of the first and second distances;
- packaging means for temporarily retaining the first and second tubular sections in overlapping relationship to provide a shipping package substantially shorter than either of said first and second distances;
- and
- means permitting said outlet end of said first tubular section to be operatively connected to said inlet end of said second tubular section is gas flow relationship when said replacement tail pipe kit is being permanently installed in one of said first and second vehicles.
A kit for replacing an OEM exhaust extension pipe in an automotive vehicle, the OEM extension pipe being unitary and having a predetermined length, comprising:
- a first tubular section having an inlet end, an intermediate portion having a predetermined configuration, and an outlet end;
- a second tubular section separate from said first section and having an inlet end, an intermediate portion having a predetermined configuration and an outlet end, the second section being approximately as long as the first section;
- packaging means for retaining said tubular sections in overlapping relationship in an assembly approximately half as long as the exhaust extension pipe replaced;
- and
- means permitting said outlet end of said first tubular section to be operatively connected to said inlet end of said second tubular section is gas flow relationship when said replacement exhaust extension pipe kit is being installed.
An improved replacement exhaust extension pipe of the type wherein an elongated tubular element is provided with an inlet end for connection to the catalytic convertor of a vehicle, an outlet end for connecting to other tubular elements of the exhaust system of said vehicle and an intermediate region between the inlet and outlet ends for extending beneath the vehicle through a passage of predetermined minimum configuration, wherein the improvement comprises:
- kit means for replacing the exhaust extension pipe of either of said vehicle and another vehicle that was originally equipped with an exhaust extension pipe having a different length from inlet to outlet ends and having an intermediate region configured to extend through a passage having a different predetermined minimum configuration, said kit means including:
- a tubular element having a first end for connection to the catalytic convertor of either of said vehicle and another vehicle, and a second end axially spaced from said first end;
- and
- tubular means for coupling with the second end of the tubular element to complete an exhaust extension pipe for either of said vehicle and another vehicle, said tubular element and said tubular means when coupled together having a length at least as great as the longer of the exhaust extension pipes with which said vehicle and another vehicle were originally equipped;
- at least one of said tubular element and said tubular means being manually shortenable;
- at least one of said tubular element and said tubular means including a non-linear portion intermediate the ends thereof;
- whereby relative rotation of said tubular element and said tubular means about the coupling therebetween will generate a plurality of spatial envelopes to permit said exhaust extension pipe kit to be employed as a replacement for a plurality of OEM exhaust extension pipes having differing OEM spatial envelopes.
