In this comprehensive guide, we'll dive deep into everything you need to know about upgrading your RC 390's exhaust system. Get ready to transform your ride!

Why Upgrade Your KTM RC 390 Exhaust?

So, why bother with a KTM RC 390 exhaust upgrade? What's the big deal? Well, the stock exhaust on the RC 390, while functional, is often designed with cost-effectiveness and noise regulations in mind. This means it can be restrictive, limiting the engine's ability to breathe freely and reach its full potential. Think of it like trying to run a marathon while breathing through a tiny straw – not ideal, right? Here's a breakdown of the key benefits:

  • Performance Enhancement: Upgrading your exhaust can significantly improve horsepower and torque. By reducing backpressure and allowing exhaust gases to escape more efficiently, the engine can produce more power throughout the rev range. This translates to quicker acceleration, improved top-end speed, and a more responsive throttle.
  • Weight Reduction: Many aftermarket exhaust systems are lighter than the stock units. This can improve the bike's handling and agility, making it easier to maneuver and more fun to ride.
  • Enhanced Sound: Let's be honest, the stock exhaust often sounds a bit… tame. An aftermarket exhaust gives your RC 390 a much more aggressive and throaty sound, turning heads wherever you go. It's the sound of performance and excitement.
  • Improved Aesthetics: Aftermarket exhausts often have a sleeker, more stylish design than the stock exhaust. They can significantly enhance the bike's appearance, giving it a more modern and aggressive look.
  • Increased Resale Value: A well-chosen exhaust upgrade can actually increase the resale value of your bike. It's a desirable modification that appeals to many potential buyers.

Basically, a KTM RC 390 exhaust upgrade is a win-win. You get a better-performing, better-sounding, and better-looking bike. What's not to love? Let's get into the nitty-gritty of choosing the right exhaust.

Types of KTM RC 390 Exhaust Systems

Alright, so you're sold on the idea of a KTM RC 390 exhaust upgrade, but where do you start? The market offers a variety of exhaust systems, each with its own pros and cons. Here's a look at the most common types:

  • Slip-On Exhausts: These are the most popular and easiest to install. They replace the muffler (the part at the end of the exhaust) while retaining the stock header pipe. Slip-ons are a great way to improve sound and aesthetics, and often provide a noticeable performance boost. They are generally the most affordable option.
  • Full Exhaust Systems: These systems replace the entire exhaust system, including the header pipe, mid-pipe, and muffler. Full systems offer the greatest potential for performance gains, as they optimize the entire exhaust flow. They typically provide the most significant horsepower and torque increases but are also the most expensive and complex to install.
  • Cat-Back Exhausts: Some systems replace the exhaust from the catalytic converter (cat) back. This can improve performance and sound without necessarily replacing the header. This is a great option if you're looking for a balance between performance, cost, and ease of installation.

Within these categories, you'll find different materials, such as:

  • Stainless Steel: Durable and cost-effective, stainless steel exhausts are a popular choice. They offer good corrosion resistance and can withstand high temperatures.
  • Titanium: Known for its lightweight and strength, titanium exhausts provide excellent performance gains and a premium look. However, they are typically the most expensive option.
  • Carbon Fiber: Carbon fiber exhausts are extremely lightweight and offer a unique, high-tech appearance. They can be more susceptible to damage than other materials, but they are a great choice for weight reduction.

Choosing the Right KTM RC 390 Exhaust System

Choosing the right KTM RC 390 exhaust upgrade can seem overwhelming, but it doesn't have to be. Here's a step-by-step guide to help you make the best decision:

  1. Define Your Goals: What are you hoping to achieve with the upgrade? Are you primarily looking for improved sound, increased performance, or a better look? This will help you narrow down your options.
  2. Set a Budget: Exhaust systems vary widely in price. Determine how much you're willing to spend to avoid overspending.
  3. Consider Your Riding Style: Do you primarily ride on the street or the track? This will influence the type of exhaust system that's best for you. For track use, you might prioritize maximum performance, while for street use, you might prefer a balance of performance, sound, and aesthetics.
  4. Research Brands and Models: Look at reputable brands like AkrapoviÄŤ, Yoshimura, Leo Vince, Two Brothers Racing, and M4 Exhaust. Read reviews, watch videos, and compare specifications to find systems that meet your needs.
  5. Check for Compatibility: Ensure that the exhaust system you choose is compatible with your specific year and model of KTM RC 390.
  6. Consider Installation: Do you plan to install the exhaust yourself, or will you have it professionally installed? If you're doing it yourself, make sure you have the necessary tools and experience. Slip-on exhausts are generally easier to install than full systems.
  7. Consider sound levels: Some exhaust systems are louder than others. If you live in an area with noise restrictions, make sure the exhaust system you choose is street legal and meets local noise regulations.

By following these steps, you can find the perfect KTM RC 390 exhaust upgrade to transform your riding experience.

Installation and Tuning

So, you've chosen your KTM RC 390 exhaust upgrade – awesome! Now comes the installation. While slip-on exhausts are often straightforward, full systems can be more complex. Here's a general overview of the installation process:

  1. Preparation: Gather your tools, including wrenches, sockets, a torque wrench, and potentially a spring puller. Make sure you have a safe workspace and follow the manufacturer's instructions.
  2. Removal of the Stock Exhaust: Carefully remove the stock exhaust system, following the manufacturer's instructions. This may involve removing fairings and other components.
  3. Installation of the New Exhaust: Install the new exhaust system, ensuring that all connections are secure and properly torqued. Pay attention to the alignment and any included mounting hardware.
  4. Tuning (If Necessary): Depending on the exhaust system and any other modifications you've made, you may need to tune your bike's fuel injection system. This is crucial to ensure optimal performance and prevent engine damage. A power commander or ECU flash can help optimize the air-fuel ratio.
  5. Final Checks: After installation, double-check all connections, and make sure there are no leaks. Start the engine and listen for any unusual sounds.

Tuning

  • ECU Flash: This involves remapping the bike's ECU (Engine Control Unit) to optimize fuel delivery and ignition timing for the new exhaust. This is often the most effective tuning method, especially for full exhaust systems. You can typically get your ECU flashed at a motorcycle shop or send it to a specialist.
  • Power Commander: This is a piggyback fuel management system that connects to your bike's existing wiring harness. It allows you to adjust the fuel map and other parameters to optimize performance. Power Commanders are often easier to install than an ECU flash.

If you're not comfortable with tuning, it's best to consult a professional mechanic. Proper tuning is crucial to get the most out of your KTM RC 390 exhaust upgrade and ensure the engine runs smoothly and reliably.

Maintaining Your Upgraded Exhaust

Once your KTM RC 390 exhaust upgrade is installed and tuned, proper maintenance is essential to keep it in top condition and ensure its longevity. Here are some tips:

  • Regular Cleaning: Clean your exhaust regularly to remove dirt, grime, and road salt. Use a mild soap and water solution and avoid harsh chemicals or abrasive cleaners.
  • Inspect for Leaks: Check for any leaks at the connections between the exhaust components. Tighten any loose bolts or clamps.
  • Check for Damage: Inspect the exhaust system for any dents, scratches, or other damage. Address any issues promptly to prevent further problems.
  • Material-Specific Care: If you have a titanium or carbon fiber exhaust, follow the manufacturer's specific care instructions. Avoid harsh cleaners and use appropriate polishing compounds.
  • Heat Shielding: Ensure that any heat shields are properly in place to protect the exhaust components from excessive heat. Check for cracks or damage to the heat shields.

By following these maintenance tips, you can keep your KTM RC 390 exhaust upgrade looking and performing its best for years to come. Remember, a little bit of care goes a long way.
