An exhaust arrangement is for an aircraft having sensing equipment and a front prop engine. An extension mounts on the underside along an edge of the fuselage to direct exhaust from the engine's exhaust pipes to a point to or past the sensing equipment typically exposed at the mid-section of the aircraft. An extension inlet mounts adjacent the pipe and defines a funnel or conical orifice not directly affixed to the pipe. One or more conductors for the extension then extend from the inlet to convey the exhaust to an outlet of the extension. Preferably, multiple conductors can be used with an expansion joint provided between them. The outlet preferably diverts exhaust away from the tail end of the aircraft. To mount the extension to the aircraft, several arrangements of supports including rods, lugs, angles, and the like hold the extension in vertical, lateral, and axial directions to the aircraft.

The apparatus of claim 1, wherein the at least one tubular comprises sheet metal rolled into a cylinder and affixed along a seam. 5. The apparatus of claim 1, wherein the second end of the at least one tubular defines an elliptical output facing away from a side of the fuselage. 6. The apparatus of claim 1, wherein the first and second supports are disposed on either side of a lift strut of a wing of the aircraft. 7. The apparatus of claim 1, wherein a first end of the first arms for the first and second supports each pivotally connect to a first doubler affixed to the fuselage; and wherein a second end of the first arms for the first and second supports each pivotally connect to a first bracket affixed to the at least one tubular. 8. The apparatus of claim 7, wherein the first bracket comprises a pair of angle brackets mounted side-by-side. 9. The apparatus of claim 7, wherein a third end of the second arms for the first and second supports each pivotally connect to the first bracket affixed to the at least one tubular; and wherein a fourth end of the second arms for the first and second supports each pivotally connect to a second doubler affixed to the fuselage. 10. The apparatus of claim 9, wherein a fifth end of the third arms for the first and second supports each pivotally connect to a second bracket affixed to the at least one tubular; and wherein a sixth end of the third arms for the first and second supports each pivotally connect to a third bracket affixed to the fuselage. 11. The apparatus of claim 10, wherein each of the first and second supports further comprise a fourth arm pivotally connected between the fuselage and the at least one tubular and supporting the same along the first axis, wherein a seventh end of the fourth arms for the first and second supports each pivotally connect to the second doubler affixed to the fuselage; and wherein an eighth end of the fourth arms for the first and second supports each pivotally connect to the second bracket affixed to the at least one tubular. 12. The apparatus of claim 1, further comprising: a third support disposed at a third of the support locations on the at least one tubular toward the first end thereof near the inlet, the third support having first, second, and third arms, the first arm pivotally connected between the fuselage and the at least one tubular and supporting the same along the first axis, the second arm pivotally connected between the fuselage and the at least one tubular and supporting the same along the second axis, the third arm pivotally connected between the fuselage and the at least one tubular and supporting the same along the first axis. 13. The apparatus of claim 12, wherein a first end of the first arm for the third support pivotally connects to a first bracket affixed to the fuselage; and wherein a second end of the first arm for the third support pivotally connects to a second bracket affixed to the at least one tubular. 14. The apparatus of claim 13, wherein the first and second brackets comprises a pair of angle brackets mounted side-by-side. 15. The apparatus of claim 13, wherein a third end of the second arm for the third support pivotally connects to the second bracket affixed to the at least one tubular; and wherein a fourth end of the second arm for the third support pivotally connects to a third bracket affixed to the fuselage. 16. The apparatus of claim 15, wherein a fifth end of the third arm for the third support pivotally connects to third bracket affixed to the fuselage; and wherein a sixth end of the third arm for the third support pivotally connects to a fourth bracket on the at least one tubular. 17. The apparatus of claim 12, further comprising: a fourth support disposed at a fourth of the support locations on the at least one tubular toward the second end thereof, the fourth support having first and second arms, the first arm pivotally connected between the fuselage and the at least one tubular and supporting the same along the first axis, the second arm pivotally connected between the fuselage and the at least one tubular and supporting the same along the second axis. 18. The apparatus of claim 17, wherein a first end of the first arm for the fourth support pivotally connects to a first bracket affixed to a double disposed on the fuselage; and wherein a second end of the first arm for the fourth support pivotally connects to a second bracket affixed to the at least one tubular. 19.
