Abstract

An exhaust gas cooling system for a vehicle includes a cooling fin system retrofit and a side exhaust pipe retrofit having an exhaust gas exit pipe having a first portion having a plurality of mixing portions which are either bends or internal mixing fins configured to mix vehicle exhaust gas, but not to restrict exhaust gas flow, a second portion fastened to the first portion and a chrome coated third portion fastened to the second portion and extending along the side of the vehicle. The cooling fin system retrofit includes an adjustable clamp and one or more cooling fins, each cooling fin having a base having a pair of upstanding arms, with one arm of the pair having a lip for engaging an arm of another cooling fin. An exhaust gas cooling system kit, a side exhaust pipe retrofit kit, a cooling fin kit are included.

Claims

1. An exhaust gas cooling system for a vehicle comprising:

a side exhaust pipe retrofit used along with a cooling fin system retrofit in a vehicle to cool exhaust gases generated by the vehicle;

the side exhaust pipe retrofit comprising;

(a) an exhaust gas exit pipe;

(b) a first clamp for fastening the exhaust gas exit pipe to a muffler of a vehicle;

(c) a mounting strap for fastening the exhaust gas exit pipe to an H pipe or a Y pipe of the vehicle; and

(d) a second clamp and a pair of rubber grommets for mounting the exhaust gas exit pipe to an exterior side of the vehicle below a door of the vehicle;

wherein the exhaust gas exit pipe comprises;

a first portion having a pair of first portion ends and a first portion pipe body extending between the pair of first portion ends, the pipe body having an outside wall, an inside diameter, and a plurality of mixing portion, each mixing portion of the plurality of mixing portions configured to mix and cool exhaust gases from a muffler of a vehicle, but not to restrict the flow of the exhaust gases;

a second portion having an a base and an arm extending from the base, the base fastened to one end of the pair of first portion ends at a point of fastening; and

a third portion having a pair of opposing curved ends and an elongate exhaust pipe middle part extending between the pair of opposing curved ends, one of the pair of opposing curved ends fastened to the arm of the second portion;

wherein one end of the pair of opposed ends of the first portion of the exhaust gas exit pipe is fastened to the muffler of the vehicle with the first clamp;

the mounting clamp is fastened to both the point of fastening of the first portion and the second portion of the exhaust gas exit pipe and to the H pipe or the Y pipe of the vehicle; and

the pair of rubber grommets are mounted to the exterior side of the vehicle below the door of the vehicle and to the elongate middle portion of the third portion of the exhaust gas exit pipe with the second clamp; and

wherein the cooling fin system retrofit comprises;

(a) one or more cooling fins, each cooling fin having a base with a pair of upright arms extending therefrom;

one of the pair of upright arms having a lip, the base and pair of upright arm portions having clamp receiving aperture portions therein forming a pair of clamp receiving apertures; and

(b) one or more adjustable clamps, each adjustable clamp dimensioned to engage within the clamp receiving apertures and each adjustable clamp either by itself or in combination with one or more adjustable clamps dimensioned to extend around an object of an exhaust gas system of a vehicle to be cooled.

2. The exhaust gas cooling system of claim 1, wherein the other upright arm of the pair of upright arms has an upper edge and wherein the lip of the upright arm of the pair of upright arms is suitably dimensioned to engage with an upper edge of an upright arm of a pair of upright arms of another cooling fin.

3. The exhaust gas cooling system of claim 1, wherein each of the clamp receiving apertures has an arm aperture portion penetrating one of the pair of upright arms and a base aperture portion penetrating the base.

4. The exhaust gas cooling system of claim 3, wherein the arm aperture portion is dimensioned to permit air flow therethrough when the adjustable clamp is engaged through the pair of aligned clamp receiving apertures.
