Removing the Muffler (Conquest Models)
On Conquests manufactured prior to C19672:
1. Remove the 2 fasteners in the top of the heat shield. Photo DE-1 Depending on the
age of the vehicle, a few earlier models utilized a fiberglass heat shield. This part is
no longer available but is fully exchangeable with the newer version.
2. Remove the 2 fasters securing the manifold cover to the muffler shield assembly and
remove the manifold cover. Photo DE-2 & 3
Collect the 2 spacers that are installed beneath each fastener

3. The lower shroud is secured by 2 more fasteners. Remove the 2 fasteners and lift the
lower shroud from the vehicle. Photo DE-4
4. Disconnect the muffler at the manifold. Photo DE-5 The muffler and exhaust mani-
fold are joined together with 2 bolts, 4 flatwashers, 2 compression springs and 2
locking style nuts. Refer to the illustration in the appropriate parts manual for a
breakdown and orientation of the hardware.

5. There are 2 fasteners securing the the entire muffler assembly to the lower body.
These are located at the lower body under the front wheel. It may prove easier to
remove the front wheel to access the fastener heads with a socket or wrench. Photo

6. Pull the muffler and shroud assembly into the engine compartment area enough for
the tailpipe to clear the outside exhaust screen. Turn the assembly 90 degrees and
shove it back over the wheel well temporarly until the exhaust manifold has been
removed. Photo DE-8
7. Unbolt the exhaust manifold and re-
move it from the engine.

8. Slide the muffler asssembly towards
the engine compartment and up and

shield to the muffler assembly. Photo DE-11
2. The above heat shield removed exposes another fastener securing the muffler to the
shrouding. Remove this fastener. Photo DE-12

Assembling and Installing the Muffler Assembly (Conquest Models)
1. On an uncluttered work surface, orient the muffler heat shield assembly with the
rubber shock lower support, to the back. Insert the muffler into the shroud with the
exhaust inlet situated to the right. Photo DE-15
DE-15 DE-16
3. Reinstall the 2 lower fasteners to secure the muffler at the bottom of the shroud.
Photo DE-17
2. Turning the tailpipe end of the shroud around to face the assembler will put the
tailpipe also to the right side of the shroud. Photo DE-16
4. Flip the assembly over and secure the muffler at the exhaust inlet end.
Photo DE-18
DE-17 DE-18
5. Secure the heat shield with the appropriate hardware. Refer to your illustrated parts
manual for correct hardware and orientation. Photo DE-19
6. Install the assembly into the vehicle at 90 degrees, compressing the rubber mounted
lower support to ease the installation and provide enough clearance in the engine
compartment. Photo DE-20 Set the assembly on to the front wheel well temporarily

When tightening down the hardware between muffler and exhaust manifold, it is
critical not to overtighten the hardware. By no means should the compression spring
become coil bound. Tighten only enough to provide a good seal between muffler and
manifold. Over tightening can cause undue stress at the muffler inlet due to the
twisting and turning of the vehicle under application. Correct tension at the
compression spring allows for movement in this area.
9. Reinstall the manifold heat shield and lower cover. Use the appropriate hardware as
illustrated in your parts manual.
10. Fasten the muffler and shroud assembly to the lower body at the front wheel well.
The lower rubber mounted support is slotted to provide adjustment for the tailpipe at
the exhaust screen hole. Ensure that the tailpipe does not touch any of the surround-
ing screen area and secure the assembly to the lower body.
