1. Akrapovic Slip On Muffler: Best Overall
Akrapovic has long been the gold standard in motorcycle exhausts, and their slip on mufflers live up to the reputation. Constructed from lightweight titanium and carbon fiber, this muffler reduces weight by up to 50% compared to the stock unit. Owner feedback consistently praises the deep, refined tone that isn’t overly loud, and our comparison of dyno charts shows a modest but noticeable power gain in the mid-to-high RPM range. The ECE approval ensures it meets noise regulations in many regions.
However, the premium price is a barrier for budget-conscious riders. If you want the best performance and finish without compromise, this is your pick. But if you’re on a tight budget or ride a less performance-oriented bike, you might find better value elsewhere.
- Race-proven titanium or carbon construction sheds up to 50% weight over stock
- Deep, refined tone with a noticeable power gain in mid- to high-RPM range
- Plug-and-play installation with included springs and mounting hardware
Pros: Exceptional build quality; Significant weight savings; Rich sound without being obnoxious
Cons: Premium price point
2. Yoshimura R-77 Slip On Muffler: Best for Sportbikes
The Yoshimura R-77 is a staple in the sportbike community, known for its aggressive sound and proven performance gains. We compared dyno results from multiple owners and found consistent increases in top-end horsepower. The stainless steel version offers durability at a reasonable weight, while carbon saves a bit more. The USFS-approved spark arrestor makes it a great choice for riders who occasionally hit the dirt.
That said, the sound is on the louder side, which might not suit everyone, especially on long tours. If you prioritize a mellow tone or need a quieter exhaust for track day noise limits, consider other options. The R-77 is best for riders who want a sporty, aggressive note and are willing to accept the volume.
- Proven race heritage with a distinctive deep growl and strong top-end pull
- Lightweight stainless or carbon construction with durable finish
- Includes spark arrestor for off-road legal use on applicable models
Pros: Excellent top-end power; Iconic sound; Spark arrestor option for dual-sport
Cons: Can be loud for some riders; Not the lightest option
3. Vance & Hines Twin Slash Staggered Slip Ons: Best for Cruisers
For cruiser riders, especially Harley owners, Vance & Hines is a trusted name. The Twin Slash Staggered slip ons deliver the deep, throaty rumble that V-twin enthusiasts crave, without overwhelming drone at cruising speeds. We looked at owner reviews and noted consistent praise for the fit and finish, with double-wall chrome that resists bluing. Installation is straightforward with basic tools, and the staggered tips add a custom touch.
However, these are heavier than many aftermarket options, partially due to the chrome construction. Also, they are model-specific, so check compatibility before buying. If you ride a metric cruiser, you may need to look at other brands. These are ideal for Harley owners seeking a classic sound and look without breaking the bank.
- Classic cruiser styling with staggered slash-cut tips for a custom look
- Deep, throaty rumble without excessive drone on the highway
- Easy bolt-on installation with included hardware for most Harley models
Pros: Authentic V-twin sound; Stylish design; Good value for a pair
Cons: Heavier than some competitors; Fitment limited to specific models
4. Two Brothers Racing M-2 Slip On Muffler: Best Value
Two Brothers Racing offers a compelling value proposition with the M-2 slip on. It sheds weight, adds a sporty tone, and includes a removable P1X tip that lets you tune the exhaust note. In our evaluation of owner feedback, many riders noted a solid performance gain for the price, making it one of the best budget options on the market. The aluminum body keeps costs down while still being lightweight.
On the downside, the aluminum finish can show wear and discoloration after extended use, especially if you ride in harsh weather. The sound, while adjustable, may lack the refinement of pricier mufflers. If you’re on a tight budget and want a noticeable upgrade, this is a great choice. But if you prioritize long-term aesthetics or a more premium note, consider spending more.
- Affordable price with excellent power-to-weight improvement
- Unique P1X power tip design for adjustable sound and performance
- Lightweight aluminum body saves significant weight over stock
Pros: Great bang for the buck; Adjustable sound via power tip; Lightweight
Cons: Finish may fade over time; Not as refined as premium brands
5. Delkevic Slip On Muffler: Best Budget
Delkevic slip ons are the go-to for riders on a shoestring budget. They offer a significant price reduction compared to name brands, while still providing a weight drop and a more aggressive sound. The universal design with an adapter means it can fit a wide range of motorcycles, which is great if you have an uncommon bike. Owner reviews often highlight the simplicity of installation.
However, you get what you pay for. The stainless steel is thin, and the welds may not be as clean as premium options. Some owners report a raspy or tinny tone that doesn’t deepen with miles. If you’re just looking for a cheap way to make your bike louder, this works. But if you want a refined sound and long-term durability, we recommend saving for a better option.
- Extremely affordable entry into aftermarket exhausts
- Universal fitment with included adapter for many bikes
- Decent weight reduction and a louder, sportier sound
Pros: Lowest price point; Universal fit works on many bikes; Easy installation
Cons: Build quality and finish are basic; Sound can be raspy or tinny
6. SC Project CR-T Slip On Muffler: Best for Track
SC Project is a favorite among track day enthusiasts and racers. The CR-T slip on is all about performance, shedding every possible gram and unleashing a raw, ear-splitting roar. In our comparison of track-oriented mufflers, this one consistently tops weight charts and dyno runs. The titanium and carbon construction is stunning, and the craftsmanship is top-notch.
But this muffler is not for the street. It lacks a removable baffle and is extremely loud, often exceeding noise limits. It also comes with a premium price. If you only ride on closed courses and want the best track performance, go for it. For street riders, the noise and legal issues make it impractical.
- Extremely lightweight for maximum performance and weight savings
- Aggressive, raw sound that screams at high RPM
- Handcrafted Italian design with premium materials
Pros: Ultimate weight reduction; Race-bred sound; Exotic looks
Cons: Very loud, not street legal in many areas; Expensive
7. FMF Q4 Slip On Muffler: Best for Dual-Sport/ADV
FMF is a leader in off-road exhausts, and the Q4 is a popular choice for dual-sport and adventure bikes. It features a USFS-approved spark arrestor, making it trail legal, and a rugged stainless steel body that can take a beating. Owner feedback highlights a deep, pleasant tone that isn’t too loud on long rides, and the weight is reasonable for the durability.
However, it’s heavier than many street-oriented slip ons, and the performance gains are modest. If you ride primarily on pavement and want maximum power, this isn’t the best pick. But for dual-sport riders who need a tough, legal exhaust that sounds good both on and off road, the Q4 is a solid choice.
- Designed for off-road performance with a spark arrestor for trail legality
- Durable construction withstands mud, rocks, and crashes better than carbon
- Deep tone that isn't overly loud for long adventure rides
Pros: Off-road ready with spark arrestor; Tough build; Good sound for ADV
Cons: Heavier than other options; Not the best for high-performance street bikes
Frequently Asked Questions
Do slip on mufflers require ECU tuning?
Not always, but it’s recommended. Many slip on mufflers are designed to work with the stock ECU and will not cause issues. However, for optimal performance and to prevent a lean condition, a fuel controller or ECU flash is beneficial, especially if you also modify the air intake. Check the manufacturer’s recommendations for your specific bike.
Will a slip on muffler make my motorcycle louder?
Yes, most slip on mufflers are louder than stock, but the increase varies. Some are designed to be relatively quiet (like the Akrapovic), while others (like the SC Project) are extremely loud. Look for dB ratings in the specifications if noise is a concern, and consider local noise laws.
Are slip on mufflers legal for street use?
It depends on the muffler and your local regulations. Many slip ons are street legal and come with a removable baffle or meet EPA noise limits. However, race-oriented models often lack a baffle and are not street legal. Always check your local laws and the product’s approval markings (e.g., ECE, USFS).
How difficult is it to install a slip on muffler?
Installation is generally straightforward and can be done with basic hand tools. Most slip ons use springs or clamps to attach to the midpipe. The process usually takes 30 minutes to an hour. Some bikes may require removing a heat shield or loosening the stock muffler. Always follow the included instructions.
Will a slip on muffler improve performance?
Yes, but the gains are typically modest, ranging from 2-5 horsepower. The main benefits are weight reduction and improved sound. A slip on alone won’t transform your bike’s performance, but combined with a fuel controller and intake, you can see more significant gains.
