Q3. Can I perform the installation myself?
A. The installation difficulty is rated as "intermediate" 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 proper sealing and safe installation, we recommend having it installed by a certified motorcycle shop or professional if you are unsure.
Q4. What is the exhaust sound and volume like?
A. Compared to the stock muffler, the low-frequency sounds are emphasized, resulting in a powerful and crisp exhaust note characteristic of a two-cylinder engine.https://www.youtube.com/watch?v=saVUoXj01pw

K-SPEED Diabolus Exhaust for Honda Rebel (CMX) 500 RB0029
Regular price
$7,437.00

(Shipping included / Tax excluded)
[For Honda Rebel 500] Diabolus Short Custom Exhaust for a Deep, Dark Style
The "RB0029" from K-SPEED’s flagship brand "Diabolus" is a slip-on short custom exhaust specially designed for the Honda Rebel (CMX) 500 (2017 and newer models).
Featuring a short bobber design that accentuates the presence of the Rebel 500’s powerful V-twin-like parallel twin engine and pulls in the rear of the bike to the absolute limit. Its blacked-out matte finish and dual-exit tail design deliver a dark and wild look that commands attention on the street.
Key Features & Specifications
Model Number (SKU):RB0029
Compatibility:Honda Rebel (CMX) 500 (2017 model onwards)
Sound Characteristics: Deep low-frequency sound and free-flowing exhaust note unique to the 500cc engine
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 physically be mounted on a Rebel 250 (2024 and older models), it lacks a silencer, which will result in very loud noise levels. On the 500, the catalytic converter located under the bike handles the muffling.
Q3. Can I install it myself (DIY)? Do I need professional expertise?
A. Since it is a slip-on type that involves removing and replacing the stock exhaust, installation is possible if you have basic tools and mechanical knowledge. However, as it requires checking exhaust gaskets and precise torque management, we recommend having it installed by a motorcycle shop or custom specialist if you are uncertain.
Q4. Is an ECU fuel remapping necessary when replacing the exhaust?
A. In principle, you can install and ride with the factory fuel settings. However, because changing to a slip-on exhaust alters exhaust efficiency, we recommend performing an ECU fuel map adjustment if you desire smoother acceleration or a reduction in afterfire.
