A flange assembly and related methods of connecting two exhaust pipes together with a flange assembly are provided. The flange assembly includes a first flange having a first mating face and a second flange connected to the first flange, wherein the second flange has a second mating face. A sealing structure is formed with the mating faces of the first and second flanges, wherein the sealing structure comprises a groove positioned on the first mating face and a ridge positioned in the second mating face, wherein the ridge occupies at least a portion of the groove with the first flange connected to the second flange.

The flange assembly of claim 1, wherein: the at least one groove comprises: a first groove; anda second groove arranged concentrically with the first groove;the at least one ridge comprises: a first ridge; anda second ridge arranged concentrically with the first ridge; andthe first and second flanges are configured to interface with one another such that: the first ridge of the second flange at least partially occupies the first groove of the first flange in a manner providing a first gas-tight seal; andthe second ridge of the second flange at least partially occupies the second groove of the first flange in a manner providing a second gas-tight seal. 3. The flange assembly of claim 1, wherein: the at least one groove is defined in the first mating face entirely about the first central aperture of the first flange; andthe at least one ridge is defined in the second mating face entirely about the second central aperture of the second flange. 4. The flange assembly of claim 1, wherein the at least one ridge is of either: rectangular cross-sectional geometry; orrounded triangular cross-sectional geometry. 5. The flange assembly of claim 1, wherein at least one of: a radial dimension of the first tubular extension is greater than a radial dimension of the first central aperture such that the first tubular extension is radially offset from an inner sidewall of the first central aperture in a manner providing a first ledge on which an end of the first pipe can be seated when that first pipe is coupled with the first central aperture of the first flange; anda radial dimension of the second tubular extension is greater than a radial dimension of the second central aperture such that the second tubular extension is radially offset from an inner sidewall of the second central aperture in a manner providing a second ledge on which an end of the second pipe can be seated when that second pipe is coupled with the second central aperture of the second flange. 6. The flange assembly of claim 1, wherein at least one of: the first central aperture extends radially under the first tubular extension of the first flange; andthe second central aperture extends radially under the second tubular extension of the second flange. 7. The flange assembly of claim 1, further comprising at least one fastener connecting the first and second flanges. 8. The flange assembly of claim 7, wherein: the at least one fastener comprises a threaded bolt and a receiving nut;at least one of the first and second flanges further comprises a counterbore hole; andthe receiving nut is configured to be positioned within the counterbore hole. 9. The flange assembly of claim 7, wherein the at least one fastener comprises: a threaded bolt; anda receiving structure substantially embedded within a recess in one of the first and second flanges. 10. The flange assembly of claim 1, wherein: the first flange is configured such that when the first pipe is coupled with the first central aperture, the first pipe is coincident with the first surface; andthe second flange is configured such that when the second pipe is coupled with the second central aperture, the second pipe is coincident with the second surface. 11. The flange assembly of claim 10, wherein the at least one ridge of the first face is longitudinally and radially offset from the at least one ridge of the second mating face. 12. The flange assembly of claim 1, wherein each of the first and second flanges has a thickness dimension of not more than 7.0 mm. 13. The flange assembly of claim 1, wherein at least one of the first and second tubular extensions has a thickness dimension that substantially matches a wall thickness of at least one of the first pipe and second pipe. 14. An exhaust flange apparatus comprising: a first flange having a first central aperture at least partially surrounded by a first tubular extension, wherein a first exhaust pipe is connectable to the first tubular extension of the first flange with a central axis of the first exhaust pipe positioned substantially concentric with a central axis of the first central aperture;a second flange having a second central aperture at least partially surround by a second tubular extension, wherein a second exhaust pipe is connectable to the second tubular extension of the second flange with a central axis of the second exhaust pipe positioned substantially concentric with a central axis of the second central aperture;a plurality of sealing structures interfaced between mating faces of the first and second flanges, wherein each of the plurality of sealing structures has a groove positioned on one of the first and second flanges and a ridge positioned on another of the first and second flanges, wherein each of the plurality of sealing structures is positioned at least partially around the first and second central apertures of the first and second flanges, respectively;at least one ridge provided on a first non-mating face of one of either the first or second flange;at least one groove provided on a second non-mating face of another of either the first or second flange; andat least one fastener connecting the first and second flanges. 15. The exhaust flange apparatus of claim 14, wherein at least one of: the first tubular extension is offset from the first central aperture in a manner providing a first recessed ledge on which the first exhaust pipe can be seated; andthe second tubular extension is offset from the second central aperture in a manner providing a second recessed ledge on which the second exhaust pipe can be seated. 16. The exhaust flange apparatus of claim 14, wherein each of the first and second flanges has a thickness dimension of not more than 7.0 mm. 17. A method of connecting two exhaust pipes together with a flange assembly, the method comprising: connecting a first exhaust pipe to a first tubular extension of a first flange having a first mating surface including at least two grooves positioned therein, and a first surface opposite the first mating surface and including at least one ridge positioned thereon, wherein a first central aperture of the first flange is substantially concentric with the first exhaust pipe;connecting a second exhaust pipe to a second tubular extension of a second flange having a second mating surface including at least two ridges positioned thereon, and a second surface opposite the second mating surface and including at least one groove positioned therein, wherein a second central aperture of the second flange is substantially concentric with the second exhaust pipe;inserting, respectively, the at least two ridges of the second mating surface into the at least two grooves of the first mating surface; andfastening the first flange to the second flange with at least one fastener. 18. The method of claim 17, wherein inserting the at least two grooves into the at least two ridges, respectively, comprises creating at least two gas-tight seals between the first and second flanges. 19.
