So, you’re looking to upgrade your motorcycle’s exhaust system? You’ve probably stumbled across the term “slip on pipes.” But what exactly are they? And why are they so popular among riders? This guide will break down everything you need to know about slip on pipes, from their basic function to the benefits they offer, helping you make an informed decision for your bike.
We’ll explore how they differ from full exhaust systems, the advantages of choosing slip ons, and what to consider when selecting the right set for your motorcycle. Whether you’re a seasoned rider or just starting out, understanding slip on pipes is a crucial step in enhancing your bike’s performance and aesthetics. Let’s get started!
What Are Slip on Pipes? The Basics
Slip on pipes, also known as slip-on exhausts or mufflers, are a type of aftermarket exhaust system designed to replace the existing muffler section of your motorcycle’s exhaust. They “slip on” to the existing headers (the pipes that connect to the engine), hence the name. This contrasts with a full exhaust system, which replaces the entire exhaust from the engine to the end of the muffler.
Key Components of a Slip on Exhaust
- Muffler/Silencer: This is the main component, responsible for reducing noise and controlling exhaust flow.
- Connecting Pipe (Mid-Pipe): This pipe connects the muffler to the existing header pipes. It might be included or sold separately depending on the manufacturer and the bike model.
- Clamps and Hardware: These are used to secure the slip on to the header and any mounting points on the bike.
Slip on Pipes vs. Full Exhaust Systems: What’s the Difference?
Understanding the difference between slip on pipes and full exhaust systems is key to making the right choice for your needs. Here’s a breakdown:
Slip on Exhausts
- Installation: Relatively easy installation. They simply slip onto the existing header pipes.
- Cost: Generally more affordable than full systems.
- Performance Gains: Moderate performance improvements, primarily in the mid-range.
- Sound: Often provide a deeper, more aggressive sound compared to the stock exhaust.
- Weight: Can be lighter than the stock exhaust, improving handling.
- Complexity: Less complex, easier to install and maintain.
- Compatibility: Compatible with the stock headers.
Full Exhaust Systems
- Installation: More complex installation, as it replaces the entire exhaust system, including headers.
- Cost: Significantly more expensive than slip ons.
- Performance Gains: Greater performance gains across the entire power band.
- Sound: Can offer a wider range of sound profiles, from aggressive to track-focused.
- Weight: Often lighter than both stock and slip-on systems.
- Complexity: More complex, requiring potential fuel mapping adjustments (ECU tuning).
- Compatibility: Not compatible with stock headers, requires complete replacement.
The choice between slip on pipes and a full exhaust system depends on your goals, budget, and mechanical skills. If you’re looking for an easy upgrade with a noticeable improvement in sound and performance, slip ons are a great option. If you’re seeking maximum performance gains and are comfortable with more complex installation and potential tuning, a full system might be the better choice.
Benefits of Installing Slip on Pipes
There are several compelling reasons why riders choose to install slip on pipes. Here are the key advantages:
Improved Sound
One of the most immediate and noticeable benefits is the enhanced sound. Slip on pipes often produce a deeper, more resonant tone that many riders find more pleasing than the often-muted sound of a stock exhaust. The improved sound can also enhance the riding experience, making the bike feel more powerful and engaging.
Increased Performance
While not as significant as the gains from a full exhaust system, slip on pipes can still improve performance. They often allow for better exhaust flow, which can result in increased horsepower and torque, particularly in the mid-range. This can translate to quicker acceleration and improved throttle response.
Weight Reduction
Aftermarket slip on pipes are often lighter than the stock exhaust. This weight reduction can contribute to improved handling and maneuverability, making the bike feel more responsive and easier to control, especially during cornering.
Enhanced Aesthetics
Slip on pipes are available in a wide variety of styles, materials, and finishes, allowing you to customize the look of your motorcycle. From sleek carbon fiber to polished stainless steel, you can choose a slip on that complements your bike’s design and reflects your personal style.
Ease of Installation
One of the biggest advantages of slip on pipes is their ease of installation. They typically bolt directly onto the existing header pipes, making them a relatively straightforward upgrade that can often be done at home with basic tools.
Cost-Effectiveness
Compared to full exhaust systems, slip on pipes are a more affordable way to upgrade your motorcycle’s exhaust. This makes them an attractive option for riders who want to improve their bike’s sound and performance without breaking the bank.
Factors to Consider When Choosing Slip on Pipes
Selecting the right slip on pipes involves considering several factors to ensure you get the best fit, performance, and style for your motorcycle.
Compatibility
Ensure that the slip on pipes are specifically designed for your motorcycle model and year. Check the manufacturer’s specifications to confirm compatibility. Using a slip on not designed for your bike can lead to performance issues and potentially damage the engine.
Material
Slip on pipes are made from various materials, each with its own advantages: (See Also: Won Hundred Willow Slip On Sneakers )
- Stainless Steel: Durable, corrosion-resistant, and offers a good balance of performance and cost.

- Carbon Fiber: Lightweight, visually appealing, and offers good heat resistance, but can be more expensive and potentially less durable than metal options.
Sound Level
Consider the sound level you desire and the legal restrictions in your area. Some slip on pipes are designed to be louder than stock exhausts, while others are designed to meet noise regulations. Check the decibel (dB) ratings to ensure the exhaust meets local requirements and your personal preferences.
Style and Aesthetics
Choose a style that complements your motorcycle’s design. Slip on pipes come in various shapes, sizes, and finishes. Consider the overall look you want to achieve, whether it’s a sleek, modern appearance or a more classic design.
Performance Characteristics
Research the performance characteristics of different slip on pipes. Some may focus on mid-range power, while others might offer gains across the entire power band. Read reviews and consult with other riders to understand how the slip on pipes perform on your specific motorcycle model.
Brand Reputation
Choose a reputable brand known for quality and performance. Research different brands and read customer reviews to assess their reliability and customer service.
Installation Difficulty
While slip on pipes are generally easy to install, some may require more involved procedures. Consider your mechanical skills and the tools you have available. If you’re not comfortable with the installation, consider having a professional mechanic do the work.
Price
Set a budget and compare prices from different manufacturers. Slip on pipes vary in price depending on the material, design, and brand. Balance your budget with your performance and aesthetic goals.
