If you’re just interested in replacing the stock exhaust, you can do that through Tao, but I highly suggest upgrading. Do not just replace the exhaust, open the airbox up, and leave you carb with the previous jetting, you will run lean and suffer a performance decrease instead of increase. Properly jet your carburetor each time you make a major modification such as this: Carburetor Upgrades
Some have drilled the silencer, replaced the cat with a straight pipe and welded it in, but honestly replacing the full exhaust is really not expensive or that hard.
Per the Facebook group, this is the exhaust to go with. Note that you will likely need to change your jetting if you do this! Check the Fuel System page for jetting suggestions.
*The fitment may require some extra effort, such as creating your own dropdown bracket. A lot go with this exhaust and have created a bracket like the one below:
