Understanding Slip-on Exhausts and Hangers
Before we dive into the installation, let’s clarify what a slip-on exhaust is and why the hanger might be a point of concern. A slip-on exhaust, as the name suggests, ‘slips on’ to your bike’s existing exhaust system, typically connecting to the header pipes. This is a common upgrade because it’s relatively easy to install compared to a full exhaust system.
The exhaust hanger is a crucial component; it’s designed to support the weight of the exhaust and prevent it from rattling or causing damage. It typically attaches to the bike’s frame and the exhaust itself. However, sometimes, aftermarket slip-on exhausts don’t perfectly align with the stock hanger location, or you might prefer a different aesthetic. This is where installing without a hanger comes in.
Why Install Without a Hanger?
There are several reasons why you might choose to install a slip-on exhaust without using the stock hanger:
- Aesthetics: Some riders prefer the cleaner look of an exhaust without a visible hanger.
- Compatibility Issues: Aftermarket exhausts might not be designed to use the stock hanger.
- Customization: You might want to reposition the exhaust or use a custom hanger.
- Simplified Installation: In some cases, omitting the hanger can simplify the installation process.
Potential Challenges
Removing the stock exhaust hanger or not using a supplied one introduces some challenges. The primary concern is ensuring the exhaust is securely mounted to the bike and doesn’t vibrate excessively. Without a proper support structure, the exhaust could potentially:
- Vibrate excessively: Leading to annoying noises and potentially damaging other components.
- Damage the exhaust: The constant movement could lead to stress fractures and leaks.
- Damage the bike: The exhaust could rub against other parts of the bike, causing wear and tear.
Therefore, when installing without a hanger, it’s critical to implement alternative methods to secure the exhaust and mitigate these risks.
