Q1. Can this be installed on the Rebel 250 or Rebel 1100?
A. No, this product is designed exclusively for the Rebel 500 (CMX500). It can be installed on the Rebel 250 (-2024), but because there is no silencer, it will be loud. It cannot be installed on the Rebel 1100.
Q2. Are there compatibility differences based on model year? (Older vs. current models)
A. Since there have been no major changes to the exhaust pipe diameter of the Rebel 500 from the original 2017 model to the current models, it can be installed on all Rebel 500 models from 2017 onwards.
Q3. Can I perform the installation myself?
A. The installation difficulty is rated for "intermediate users" and requires basic tools such as screws, a screwdriver, and a wrench. If you are comfortable using general tools, you can install it yourself; however, to ensure safe installation and prevent exhaust leaks, we recommend having it installed by a certified motorcycle shop or professional if you are unsure.
Q4. What kind of exhaust sound and volume does it have?
A. Compared to the stock muffler, the bass is emphasized, changing the sound to a powerful, crisp exhaust note typical of a 2-cylinder engine. https://www.youtube.com/watch?v=saVUoXj01pw

Frequently Asked Questions (FAQ)
Q1. Which models and years is the K-SPEED RB0029 exhaust compatible with?
A. It is compatible with all Honda Rebel (CMX) 500 models from 2017 onwards. Please note that it is not compatible with the Rebel 250 or Rebel 1100 due to differences in exhaust pipe diameter and mounting points.
Q2. Can it be installed on a Rebel 250?
A. No. While the RB0029 can be physically mounted on a Rebel 250 (models prior to 2024), it does not have a silencer, which will result in a very loud volume. On the 500, the exhaust is silenced by the catalytic converter located under the vehicle chassis.
Q3. Can I install this myself (DIY)? Do I need professional expertise?
A. As it is a slip-on type that involves removing and replacing the stock muffler, it can be installed with basic tools and maintenance knowledge. However, because it requires checking exhaust gaskets and precise torque management, we recommend having it installed by a motorcycle shop or custom specialist if you are not confident.
Q4. Is an ECU fuel map adjustment (injection tuning) necessary when replacing the exhaust?
A. In general, it is possible to install and ride the bike with the stock fuel settings. However, since slip-on replacement changes exhaust efficiency, we recommend using an ECU fuel map adjustment if you desire smoother acceleration and a reduction in afterfire.
