Abstract: Exhaust systems for a vehicle are provided. In one example, an exhaust system includes a muffler, a first exhaust outlet pipe fluidly coupled to a first outlet of the muffler, a second exhaust outlet pipe fluidly coupled to a second outlet of the muffler, a bypass duct fluidly coupled to a third outlet of the muffler, and a combined X-Y shaped intersection at which the first exhaust outlet pipe, the second exhaust outlet pipe, and the bypass duct are fluidly coupled to each other.

Abstract: A vibration isolation system reduces rattling in a reverse lockout mechanism for a manual shifter. A shaft retained in a shifter housing has an upper end for a shift knob and an enlarged barrel section proximate the housing. A lockout skirt slides on the shaft between upper and lower positions. The lockout skirt has a shoulder extending radially outward, and the housing includes a stop block such that the shaft is prevented from pivoting to a reverse gear position when the lockout skirt is in the lower position and is free to move to the reverse gear position when the lockout skirt is in the upper position. A spring retained on the shaft biases the lockout skirt toward the lower position. A plurality of lubricated O-rings are disposed on the shaft to define sliding interfaces between the lockout skirt and the shaft and between the lockout skirt and the barrel.

Abstract: A manual transmission shifter includes a reaction arm mounting the shifter to a transmission via a bushing. The bushing includes a resilient member having a tubular section lining a mounting hole in the arm and having a flange extending around the hole. The bushing includes a rigid cup member having an inner sleeve disposed within the tubular section and having a cup rim defining a recess between the inner sleeve and cup rim with a predetermined depth. The flange has a thickness greater than the predetermined depth and is inserted in the recess to create an open gap between the cup rim and the arm. A fastener extends through the inner sleeve to attach the cup member to a transmission bracket. The resilient member attenuates vibrations through the bushing. The arm is provided with a limited range of longitudinal rotation by contact of the arm with the cup rim.
