Abstract
Abstract The apparatus would include a body portion positionable intermediate the exhaust manifold and the muffler or the catalytic converters if the car is adapted with such, so that exhaust gases, under a first condition, can flow through the body portion and into the muffler prior to exiting to atmosphere, and under a second condition, via the removal of a plate member, a greater portion of the exhaust gases would be exhausted directly out to atmosphere bypassing the remainder of the exhaust system including the muffler and/or catalytic converter.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
165 words
An apparatus for functioning as a header in an exhaust system of a vehicle, the apparatus positionable between an exhaust manifold and an exhaust muffler system, the apparatus comprising a body having a forward body portion connectable to the exhaust manifold, a rearward body portion having opposing ends wherein at least one of said ends is connectable to the exhaust muffler system, and a main body portion having extruded therefrom the rearward body portion at the other of said ends, and comprising an exhaust gas flow area with the rearward body portion, the main body portion further having an end plate threadably engaged onto an end of the main body portion so that in a first secured position the end plate directs flow of exhaust gases into the exhaust muffler system, and in the second unsecured position allows flow directly out of the main body portion so that the main body portion functions as a header for expelling gases to atmosphere bypassing the muffler system.
Claim 2
Independent Claim
165 words
An apparatus for functioning as a header in an exhaust system of a vehicle, the apparatus positionable between an exhaust manifold and an exhaust muffler system, the apparatus comprising a body having a forward body portion connectable to the exhaust manifold, a rearward body portion having opposing ends wherein at least one of said ends is connectable to the exhaust muffler system, and a main body portion having extruded therefrom the rearward body portion at the other of said ends, and comprising an exhaust gas flow area with the rearward body portion, the main body portion further having an end plate threadably engaged onto an end of the main body portion so that in a first secured position the end plate directs flow of exhaust gases into the exhaust muffler system, and in the second unsecured position allows flow directly out of the main body portion so that the main body portion functions as a header for expelling gases to atmosphere bypassing the muffler system.
Claim 3
Dependent Claim
192 words
A vehicle exhaust adapter apparatus, comprising: a. a main body portion; b. a forward body portion connectable to an exhaust manifold; c. a rearward body portion extruded at one end thereof from the main body portion and connectable at another end thereof to a vehicle exhaust muffler system wherein the main body portion comprises an exhaust gas flow area with the rearward body portion; and d. directing means positionable on the main body portion for selectively allowing exhaust gases traveling through the adapter to flow through the exhaust muffler system when the directing means is in a first, secured position and to substantially bypass the exhaust muffler system and to exhaust directly into atmosphere when the directing means is in a second, unsecured position, wherein the directing means comprises an end plate positionable upon the rearwardmost end portion of the main body portion, the end plate threadably engaged to the rearwardmost end portion of the main body portion for enabling exhaust gases to flow through the exhaust muffler system, and when unsecured from the body portion allowing exhaust gases to flow through the main body portion and bypass the exhaust muffler system.
Claim 4
Dependent Claim
192 words
A vehicle exhaust adapter apparatus, comprising: a. a main body portion; b. a forward body portion connectable to an exhaust manifold; c. a rearward body portion extruded at one end thereof from the main body portion and connectable at another end thereof to a vehicle exhaust muffler system wherein the main body portion comprises an exhaust gas flow area with the rearward body portion; and d. directing means positionable on the main body portion for selectively allowing exhaust gases traveling through the adapter to flow through the exhaust muffler system when the directing means is in a first, secured position and to substantially bypass the exhaust muffler system and to exhaust directly into atmosphere when the directing means is in a second, unsecured position, wherein the directing means comprises an end plate positionable upon the rearwardmost end portion of the main body portion, the end plate threadably engaged to the rearwardmost end portion of the main body portion for enabling exhaust gases to flow through the exhaust muffler system, and when unsecured from the body portion allowing exhaust gases to flow through the main body portion and bypass the exhaust muffler system.
Claim 5
Dependent Claim
24 words
The apparatus in claim 2, wherein the apparatus functions as a direct exhaust header through which the engine exhaust gases are expelled to atmosphere.
Claim 6
Dependent Claim
30 words
The apparatus in claim 2, wherein the apparatus is easily positionable between the exhaust manifold and the exhaust muffler system and does not require being removed when not in use.
Claim 7
Dependent Claim
27 words
The apparatus in claim 8, wherein the forward body portion comprises a pipe of substantially the same circumference as the exhaust manifold and is secured directly thereto.
