Exhaust finisher retention operation
An exhaust system for a vehicle features a pipe finisher including an inner sleeve. The inner sleeve has a reduced diameter portion spaced upstream from a downstream end of the inner sleeve. An exhaust pipe disposed in the inner sleeve, the exhaust pipe including a radially outward extending projection downstream of the reduced diameter portion of the inner sleeve.
1. An exhaust system for a vehicle comprising:
a pipe finisher including an inner sleeve having a first inner diameter and a downstream end, wherein the inner sleeve has inwardly extending ribs spaced around a circumference of the inner sleeve, the inner sleeve having a second inner diameter at the ribs less than the first inner diameter; and
an exhaust pipe disposed in the inner sleeve, the exhaust pipe including a radially outward extending projection positioned downstream of the ribs of the inner sleeve.
2. The exhaust system of claim 1 , wherein an outer diameter of the exhaust pipe including the radially outward extending projection is greater than the second diameter of the inner sleeve.
3. The exhaust system of claim 2 , wherein a portion of the exhaust pipe upstream of the radially outward extending projection has an outer diameter less than or equal to the second diameter of the inner sleeve.
4. The exhaust system of claim 2 , wherein a portion of the exhaust pipe upstream of the radially outward extending projection has a diameter greater than the second diameter of the inner sleeve, and wherein the ribs of the inner sleeve are operable in response to insertion of the exhaust pipe into the inner sleeve to be biased radially outward.
5. The exhaust system of claim 2 , wherein the second diameter of the inner sleeve is a first reduced diameter portion and the downstream end of the inner sleeve is a second reduced inner diameter portion, and wherein the radially outward extending projection of the exhaust pipe is disposed axially between the first and second reduced inner diameter portions of the inner sleeve.
6. The exhaust system of claim 1 , wherein at least a portion of the radially outward extending projection is circumferentially aligned with at least one rib of the inner sleeve.
7. The exhaust system of claim 1 , wherein the downstream end of the inner sleeve includes a lip extending radially inward and defining an aperture, and wherein a downstream end of the exhaust pipe adjacent the lip has a greater outer diameter than a diameter of the aperture.
8. The exhaust system of claim 7 , wherein the radially outward extending projection of the exhaust pipe is axially spaced between the second inner diameter of the inner sleeve and the lip of the inner sleeve.
9. The exhaust system of claim 1 , wherein the radially outward extending projection of the exhaust pipe includes a plurality of circumferentially spaced radially outward extending projections.
10. A vehicle comprising:
an exhaust system including an exhaust pipe having a downstream end defining an outlet in communication with an ambient environment about the vehicle and having a radially outward extending projection upstream of the outlet; and
a pipe finisher around the downstream end of the exhaust pipe, the pipe finisher including:
an inner sleeve having a first inner diameter and a downstream end, wherein the inner sleeve has inwardly extending ribs spaced around a circumference of the inner sleeve, the inner sleeve having a second inner diameter at the ribs less than the first inner diameter,
where the radially outward extending projection of the exhaust pipe is located downstream of the ribs of the inner sleeve.
11. The vehicle of claim 10 , wherein the radially outward extending projection of the exhaust pipe includes a plurality of circumferentially spaced radially outward extending projections.
