Part: Honda CL350 / CL360 / CL450 Scrambler Mufflers - Sold In Pairs - Does Not Qualify for Free Shipping
Why You Need This: Don't be surprised to find holes rusted clean through the mufflers on that Honda CL350 / CL360 / CL450 scrambler you just bought. Finding replacement mufflers for the Honda CL350 / CL360 / CL450 that actually fit is next to impossible. So, we sourced these mufflers as clean replacements for the rust-prone factory originals. While not exact reproductions of the original scrambler mufflers, they look appropriate and fit very well once the brackets are configured (see installation tips below). This is a much cheaper alternative to aftermarket scrambler pipes and will optimize engine performance (and noise) compared to open headers. While these slip-on mufflers are small enough to work on the CL bikes, they also serve as a low-profile option for CB motorcycles. Mufflers are sold in pairs.
Note: The inlet side of these mufflers is the correct size for the header pipe diameter on the Honda CL350 / CB350, CB360 / CL360, and CL450 when used with the graphite muffler gaskets. The CJ360 / CB450 / CB500T has a slightly larger header pipe diameter, so while the mufflers will fit over the header, there isn't enough clearance for a full-sized graphite gasket on the 450.
Installation Tips: Most factory CL exhaust systems are welded together and will require cutting at least one of the mufflers off its respective header pipe. How far back each header can be cut depends on your specific bike's sub-model. For instance, the CL350 K0 headers remain straight further back on the bike compared to later model 350s and 360s. Your bike will require its own custom bracket. No two bikes are exactly the same, and where you cut the header pipe significantly affects where your mufflers can mount and how your brackets fit together. Regardless of which bike you have, it is a good idea to replace the Copper Exhaust Gaskets while the system is apart.
Since these mufflers are universal parts, they will need somewhat custom brackets to fit your bike. Fortunately, each muffler comes with a generic bracket, allowing you to derive a solution using nothing more than a hacksaw and a power drill. See the pictures above for one such solution on a Honda CL350 K4. In this example, the top bracket mounts to the rearmost end of the mounting slot on the top muffler. This bracket received a hole to hang the lower bracket, a notch to clear the shock absorber, and a second hole to mount to the shock stud (M10). The lower mount bolted to the lower muffler mounting slot near the center, extending upwards parallel to the shock absorber and ultimately connecting to the upper bracket with an M8 bolt, lock washer, and nut.
The whole process required a drill press, two drill bits, a hacksaw with a multi-purpose blade, a file, and roughly an hour of time. Depending on the diameter of your shock absorbers, you may want to trim the mounting bracket on the lower muffler to avoid interference. If you don't like the look of the brackets, you can always drill a bunch of speed holes, paint them black, or fabricate your own super-cool brackets. Send us a photo if you do!
Optional Part Graphite Exhaust Pipe Gasket: Want the best seal for your new mufflers? We sell graphite pipe adapters as an upgrade to the units included in the kit. These adapters compress and conform to the pipes to provide the best possible seal. These graphite exhaust pipe gaskets will only fit the Honda CL350 / CB350 and CB360 / CL360 factory header pipes.
