Installing an aftermarket exhaust is a great way to increase your motorcycle's horsepower. But many riders wonder whether they can do this job themselves or if they need a professional. The answer is, it depends.  Most aftermarket exhausts require some knowledge of mechanics and tools like wrenches, screwdrivers, and socket sets.  If you have these skills and the right tools, you should be able to install an aftermarket exhaust. If not, it's better to leave it to a professional mechanic. They'll have the skills and experience needed for the job – plus access to any parts that may be required during installation. It's worth spending the money for peace of mind that your aftermarket exhaust is installed properly.
