Why Upgrade Your Triumph Trident 660 Exhaust?

So, why bother upgrading the exhaust on your sleek Triumph Trident 660? Isn't the stock system good enough? While the factory exhaust does its job, there are several compelling reasons to consider an aftermarket upgrade. First off, performance gains are a major draw. Aftermarket exhausts are often designed with better flow dynamics, allowing your engine to breathe more freely. This can translate to noticeable improvements in horsepower and torque, especially in the mid-range where you need it most for everyday riding and spirited cornering. Think snappier acceleration and a more responsive throttle. Secondly, it's all about the sound. Let's be honest, the Trident is a beautiful bike, but the stock exhaust can be a little… tame. Upgrading to a sportier exhaust system unlocks a symphony of sound, from a deep rumble to a high-pitched scream, depending on your preferences. This not only enhances the riding experience but also increases your visibility to other motorists, making you safer on the road. Thirdly, weight reduction is another bonus. Many aftermarket exhaust systems are made from lighter materials like stainless steel or titanium, shaving off precious pounds and improving the bike's handling. This can make the Trident feel even more nimble and responsive, especially when carving through corners. Finally, aesthetics play a big role. An aftermarket exhaust can dramatically change the look of your bike, giving it a more aggressive and customized appearance. It's a statement piece that reflects your personal style and sets your Trident apart from the crowd. So, whether you're chasing performance, sound, weight savings, or simply want to personalize your ride, an exhaust upgrade is a fantastic way to enhance your Triumph Trident 660.

The Benefits Breakdown:

• Performance: Increased horsepower and torque, improved throttle response.
• Sound: A more engaging and assertive exhaust note.
• Weight: Reduction in overall weight for improved handling.
• Aesthetics: A customized look that enhances the bike's appearance.
• Safety: Increased visibility to other motorists.

Types of Exhaust Systems for Your Trident 660

Alright, let's dive into the different types of exhaust systems you'll encounter when shopping for your Triumph Trident 660. Understanding the options is key to making the right choice for your needs and budget. The main categories are slip-ons and full systems, each with its own advantages and considerations.

Slip-on Exhausts

Slip-on exhausts are the most common and accessible upgrade option. They replace the muffler (the rear section of the exhaust system) while retaining the original headers (the pipes that connect to the engine). Installation is usually straightforward, often requiring only basic tools and a bit of elbow grease. The benefits of a slip-on include a noticeable improvement in sound and a modest gain in performance, typically a few horsepower. They're also relatively affordable compared to full systems, making them a great entry point into the world of aftermarket exhausts. Moreover, slip-ons are often available in a wide variety of styles and finishes, allowing you to easily change the look of your bike. The downsides? The performance gains are less significant than with a full system, and you won't see any weight savings from replacing the headers. Nevertheless, slip-ons are an excellent choice for riders who want a significant upgrade in sound and aesthetics without breaking the bank or tackling a complex installation.

Full Exhaust Systems

Full exhaust systems are a more comprehensive upgrade, replacing the entire exhaust system from the headers back. This includes the headers, mid-pipe, and muffler. This type of system offers the most significant performance gains, as it optimizes the entire exhaust flow. You can expect a more substantial increase in horsepower and torque, along with a noticeable reduction in weight. Full systems also offer the ultimate in customization, with a wider range of materials, finishes, and designs to choose from. However, full systems come with a higher price tag and a more involved installation process. You might need to have your bike's ECU (Engine Control Unit) remapped to fully realize the performance benefits, ensuring the correct fuel-to-air ratio. Remapping optimizes the engine's performance to match the new exhaust and maximizes the gains. Full systems are ideal for riders who are serious about performance and are willing to invest in a top-tier upgrade.

Understanding the Components

• Headers: The pipes that connect directly to the engine's exhaust ports.
• Mid-pipe: The section of pipe that connects the headers to the muffler.
• Muffler/Silencer: The rear section of the exhaust, responsible for controlling sound and exhaust flow.

Key Considerations When Choosing an Exhaust

Choosing the right exhaust for your Triumph Trident 660 involves more than just picking a pretty pipe. You'll want to take a few crucial factors into account to ensure you get the best possible outcome for your riding style and needs. It's like finding the perfect pair of boots – they need to fit well, look good, and perform the way you expect. Let's break down the important things to keep in mind.

Sound Level and Style

Sound level is a big one. Do you want a loud, aggressive roar or a more subtle, refined growl? Consider the local noise regulations in your area, as some exhausts are louder than what's legally permissible. Also, think about your neighbors and how the sound might impact them. Exhaust manufacturers often provide sound level ratings (measured in decibels, or dB) to help you make an informed decision. Besides the sound, the style of the exhaust is crucial for your bike's aesthetics. Do you prefer a sleek, minimalist look, or a more bold and eye-catching design? Some exhausts have a traditional, round shape, while others have a more modern, angular design. The material and finish also play a role, with options including stainless steel, titanium, carbon fiber, and various colors and coatings. Your choice will significantly impact your bike's overall appearance.

Performance Goals

What are your goals for the exhaust upgrade? If you're primarily concerned with sound and aesthetics, a slip-on exhaust might be sufficient. However, if you're looking for maximum performance gains, a full exhaust system is the way to go. Consider how you ride and what improvements you're seeking. Do you want more power for track days or improved acceleration for street riding? Your riding style should influence your decision.

Material and Build Quality

Material and build quality are directly related to the exhaust's longevity, performance, and appearance. Higher-quality materials like stainless steel and titanium are more resistant to corrosion and offer better heat resistance, extending the exhaust's lifespan. Lighter materials like titanium also reduce the overall weight of the bike, improving handling. Pay attention to the welding and craftsmanship, as a well-built exhaust will fit properly and last longer. Look for reputable brands that have a good track record and positive reviews. The quality of materials and construction can significantly impact both the performance and the durability of your new exhaust.

Price and Budget

Exhaust systems vary widely in price, so it's essential to set a budget before you start shopping. Slip-on exhausts are typically more affordable than full systems. Consider your budget constraints and prioritize the features that are most important to you. Don't forget to factor in the cost of installation (if you're not doing it yourself) and any potential remapping required for full systems. It is essential to balance your needs with what you can afford comfortably.

Installation: Can You Do It Yourself?

So, you've chosen your dream exhaust. Now what? The good news is that installing a slip-on exhaust on your Triumph Trident 660 is usually a straightforward process that most riders can handle themselves. Full exhaust systems, however, are a bit more involved and might require some mechanical experience. Let's break down the installation process.

Slip-on Exhaust Installation

For a slip-on, you'll typically need a few basic tools: a socket set, a wrench, possibly a torque wrench, and some penetrating oil (just in case). The process involves removing the old muffler, attaching the new one, and securing it. The instructions provided with the exhaust will guide you step-by-step. Remember to disconnect the battery before starting any work on the electrical system. Take your time, follow the instructions carefully, and double-check all connections to ensure everything is secure. YouTube is an excellent resource for visual guides. If you are not comfortable working on your bike, it's always best to seek professional help.

Full Exhaust System Installation

Installing a full exhaust is more complex, as it involves removing the entire stock exhaust system, including the headers. You'll need more tools, including potentially an exhaust spring puller, and the process will take longer. You'll likely encounter more bolts and connections, and the headers may be tricky to remove. With full systems, it is highly recommended to have your bike's ECU professionally remapped after the installation. Remapping optimizes the engine's fuel-to-air mixture to take advantage of the increased exhaust flow and maximize performance. If you're not comfortable with this level of mechanical work, it's best to have a qualified mechanic perform the installation and remapping.

Tips for a Smooth Installation

• Read the instructions carefully before you start.
• Gather all the necessary tools and ensure you have a clean workspace.
• Use penetrating oil on any stuck bolts or connections.
• Torque bolts to the manufacturer's specifications.
• Double-check all connections before starting your engine.
• Consider a professional installation if you're unsure about any step.

Legal Considerations and Noise Regulations

Before you rev up that new exhaust, it's important to understand the legal considerations and noise regulations in your area. Laws vary by region, so it's your responsibility to ensure your exhaust system complies with local regulations. Things to consider:

Noise Levels

Most jurisdictions have noise level limits for motorcycles, typically measured in decibels (dB). Check the sound level rating of your chosen exhaust and compare it to the legal limits in your area. Exceeding the noise limits can result in fines and, in some cases, the requirement to replace your exhaust with a quieter one. Also, remember that modifications like removing the baffle on your new exhaust will make it louder and possibly non-compliant.

Emissions Standards

Some regions have emission standards that your exhaust system must meet. Aftermarket exhausts are generally designed to be compliant with these standards, but it's essential to verify this before purchasing. Consider whether the exhaust is street-legal in your area.

Road-Legal Status

Some exhaust manufacturers offer exhausts that are specifically designed to be road-legal, often with a certification stamp. Look for these if you want to ensure compliance with all applicable regulations. This is particularly important if you live in an area with strict enforcement of noise or emissions laws. Doing your research on local regulations will keep you riding legally and avoid potential issues.
