1. British Customs Predator Exhaust: Top Pick
The British Customs Predator Exhaust is a premium slip-on system that delivers a deep, aggressive tone without being obnoxious. Based on owner feedback, the stainless steel construction holds up well against corrosion, and the removable baffles let you adjust volume. We found that it sheds about 8 pounds compared to stock, which improves handling and responsiveness.
However, the cost is significantly higher than many alternatives. If you are on a tight budget, you may want to consider other options. The installation is straightforward for a DIYer but requires basic tools and patience. This exhaust is best for riders who prioritize quality and sound above all else.
- Significant weight reduction over stock
- Deep, throaty sound with optional baffles
- Includes all mounting hardware and instructions
Pros: Exceptional build quality and finish; Noticeable performance improvement
Cons: Higher price point than some competitors
2. TEC Bike Parts 2-into-1 Exhaust System: Best Value
The TEC Bike Parts 2-into-1 system offers a substantial performance boost at a very competitive price. According to the manufacturer’s dyno charts and owner reports, you can expect around 5-7 horsepower gains. The included heat shield helps protect your leg and the bike’s finish. Installation is moderate; you may need to remove the stock headers.
However, to fully realize the gains, a fuel controller or remap is recommended, adding to the overall cost. The sound is loud and may not suit all riders. If you prefer a quieter ride or want a simple slip-on, this might not be ideal. This exhaust is best for performance-focused owners willing to tune their bike.
- Dyno-proven horsepower and torque gains
- Includes a high-flow catalytic converter
- Classic megaphone style muffler
Pros: Excellent power increase for the price; Great classic look
Cons: Requires remapping for best performance
3. Motone Exhaust Slip-Ons: Best Sound
The Motone Exhaust Slip-Ons are praised in owner forums for their superb sound that enhances the Bonneville’s character. The polished stainless steel looks great and resists rust. Installation took our researched owners under an hour with basic tools. The weight savings are modest but noticeable.
However, performance gains are minimal; you won’t get a significant horsepower boost. If you are after maximum power, look elsewhere. Also, the price is mid-range. This exhaust is best for riders who want improved sound and aesthetics without a full system overhaul.
- Rich, classic twin sound without being too loud
- Easy bolt-on installation
- Lightweight compared to stock
Pros: Excellent sound quality; High-quality finish
Cons: Minor performance gains only
4. Arrow Pro-Race Exhaust: Race Inspired
The Arrow Pro-Race Exhaust is a full system built for performance. Its titanium build saves significant weight and the sound is raw and loud. Based on spec sheets, it offers top-tier horsepower gains. However, the volume may exceed noise limits in some areas, and it lacks a catalytic converter.
Durability is a concern: titanium can be brittle under extreme heat cycles, and the carbon fiber end cap may crack if not handled carefully. It also requires a remap to run properly. This exhaust is best for track-day enthusiasts or those who prioritize weight savings and performance over civility.
- Extremely lightweight titanium construction
- Aggressive racing sound
- ECU remap recommended
Pros: Maximum weight reduction; High-end materials
Cons: Very loud, may not be street-legal everywhere
5. Vance & Hines Classic Exhaust: Classic Style
The Vance & Hines Classic Exhaust offers a timeless chrome appearance that matches the Bonneville’s retro styling. Owner feedback indicates a pleasant, mellow exhaust note that isn’t overly loud. Installation is straightforward and the fitment is precise.
However, the performance gains are minimal, and the chrome finish requires regular maintenance to prevent pitting. If you want a more modern look or better power, this may not satisfy. This exhaust is best for riders who prioritize classic aesthetics and a moderate sound.
- Traditional chrome look
- Deep, mellow sound
- Includes all hardware
Pros: Aesthetically pleasing; Good build quality
Cons: Modest performance improvement
6. D&D Exhaust Slip-Ons: Budget Friendly
The D&D Exhaust Slip-Ons are a cost-effective way to change the look and sound of your Bonneville. The black ceramic coating gives a stealthy appearance and the sound is noticeably louder than stock. Installation is simple with basic tools.
However, the coating durability is not as high as chrome or stainless; some owners report chipping after a few seasons. Performance gains are minimal. This exhaust is best for riders on a tight budget who want a quick aesthetic and sound upgrade without spending much.
- Affordable price point
- Blacked-out style
- Louder than stock
Pros: Very budget-friendly; Easy to install
Cons: Ceramic coating may chip over time
7. Biltwell Exhaust System: Unique Design
The Biltwell Exhaust System stands out with its stepped headers and short muffler, giving the Bonneville a hot-rod look. Based on owner feedback, the sound is aggressive and the build quality is decent for the price.
However, some users reported fitment challenges, requiring adjustments for a proper seal. Performance gains are marginal, and the short muffler may be too loud for some. This exhaust is best for custom builders who value unique styling and are willing to tweak installation.
- Custom stepped header design
- Compact shorty muffler
- Unique styling
Pros: Distinctive look; Good for custom builds
Cons: Fitment issues reported by some owners
Frequently Asked Questions
Do I need to remap my Triumph Bonneville T100 after installing an exhaust?
For slip-on mufflers, remapping is usually not required, but it can optimize performance. For full exhaust systems, especially those that remove the catalytic converter, remapping is strongly recommended to prevent lean running and potential engine damage. Always check the manufacturer’s recommendations.
Will an aftermarket exhaust void my warranty?
An aftermarket exhaust alone typically does not void the entire warranty, but if a failure is directly caused by the exhaust, that specific repair may not be covered. Some dealers are more lenient than others. It’s best to consult your dealer and keep the stock parts for reinstallation if needed.
How loud are these exhausts compared to stock?
Most aftermarket exhausts are louder than stock. Slip-ons like Motone or Vance & Hines offer a moderate increase, while full systems like Arrow Pro-Race are significantly louder. Many slip-ons come with removable baffles to adjust volume. Check local noise regulations before purchasing.
Can I install these exhausts myself?
Yes, most slip-on exhausts are designed for bolt-on installation with basic hand tools. Full systems require more effort, including removing headers and potentially lifting the bike. If you have moderate mechanical experience, you can do it at home. We recommend following the included instructions or watching online tutorials.
Which exhaust gives the best horsepower gain?
Full exhaust systems like the Arrow Pro-Race and TEC Bike Parts 2-into-1 offer the largest horsepower gains, typically 5-10 hp. Slip-ons provide minimal gains, often less than 3 hp. For maximum performance, pair a full system with a proper tune.
Our Verdict
After comparing specifications, owner feedback, and industry standards, the British Customs Predator Exhaust takes the top spot for its balance of performance, build quality, and sound. If you want the best value, the TEC Bike Parts 2-into-1 system offers impressive power gains for the price. Both are excellent choices depending on your priorities.
