LeoVince LV ONE EVO Full Exhaust
What We Like
- Compatible with three major Yamaha 900cc platforms.

Replacing the entire factory exhaust, this full system is compatible with three major Yamaha 900cc platforms. Its listed weight of 14.6 pounds indicates a more involved installation than a slip-on. LeoVince is described as one of the most popular manufacturers, and the product includes a catalyst as noted in the Amazon title.
A full system like this requires more installation time than a simple slip-on muffler. For comparison, the KJTYSDM Carbon Slip-On Muffler is listed at 2.2 pounds, representing a much lighter and simpler component. The LV ONE EVO’s design is a comprehensive change for riders committed to that specific upgrade path.
KJTYSDM Carbon Slip-On Muffler
What We Like
- Very compact cylindrical and angled profile
- Stainless steel construction for durability
- Offers a performance-inspired visual update
- Lightweight at just 2.2 pounds
Trade-offs
- Installation may require additional parts not included
- Short 310 mm length may not suit all aesthetic preferences
- Check local legality for sound and emissions is required
With a main body length of about 7.7 inches, the KJTYSDM Carbon Slip-On Muffler presents a compact cylindrical profile. This short format is intended for custom layouts where space is limited, allowing it to tuck in neatly. Its stainless steel construction and carbon-fiber-patterned surface provide a modified appearance, while the 2.2-pound weight suggests a potential reduction compared to stock components.
Installation requires careful preparation, as this slip-on modification part may need a model-specific mid-pipe, adapter, or bracket not included. Professional installation is recommended, and all connections must be secured before starting the engine. Buyers are also responsible for checking that the exhaust change complies with local sound and emissions rules, as it is not a certified emissions component.

How We Evaluated Exhausts For Yamaha MT-09
Our evaluation focused on researching specifications from manufacturers, analyzing expert round-ups, and identifying consistent patterns in owner feedback. We prioritized criteria like installation type (full system vs. Slip-on), construction quality, and overall performance impact. For instance, a lightweight, compact slip-on serves a different purpose than a full exhaust that alters the bike’s entire routing.
Owners should also check local regulations for sound and emissions compliance, which is an additional consideration. This evaluation is based on product specifications and user reports.
What To Look For In Exhausts For Yamaha MT-09
The primary choice is between a full exhaust system and a simpler slip-on muffler. Your decision hinges on how much performance gain, weight savings, and installation effort you’re ready for.
Decide first between a full exhaust for major performance gains or a slip-on for simpler looks and sound. Check fitment for your specific MT-09 year, and always verify local sound and emissions legality.
Installation Complexity
A full system like the LeoVince LV ONE EVO replaces the entire factory exhaust from the headers back, which is a more involved process than installing a slip-on. This route often requires removing the stock headers and rerouting pipes, potentially needing an oxygen sensor relocation kit. Conversely, a slip-on muffler typically bolts to the existing mid-pipe, though some may require additional parts not included. A good resource for understanding the commitment is our guide on how to install a motorcycle exhaust.
Performance Goals
A high-quality full system aims for significant weight reduction and power gains across the RPM range, often through improved airflow and the inclusion of a performance catalyst. Slip-ons primarily change the exhaust note and offer a lighter, performance-inspired visual update with more modest power improvements. The debate over which route offers the best value is central to discussions about slip-on vs full exhaust systems.
Sound, Fit, and Legality
Sound preference is subjective, but a throatier note is a common goal. Ensure any exhaust explicitly fits your MT-09’s model year. Most importantly, you must check local regulations regarding noise limits and emissions compliance, as aftermarket parts can make your bike illegal for road use.
- Confirm the product listing includes your MT-09’s exact year.
- Listen to sound clips online to gauge the exhaust tone.
- Research your state or country’s specific vehicle modification laws.
The most important factor is ensuring the exhaust is legal for your area and a proper fit for your bike.

Frequently Asked Questions
What is the best exhaust for a Yamaha MT-09?
The best overall exhaust is the LeoVince LV ONE EVO Full Exhaust for riders wanting a complete, high-quality performance transformation. If you prefer a simpler, lightweight slip-on for a minimalist look, the KJTYSDM Carbon Slip-On Muffler is an excellent compact choice.
What exhaust gives the best sound?
Sound is subjective, but full exhaust systems generally offer a deeper, more performance-oriented tone by redesigning the entire airflow path. Slip-on mufflers alter the sound primarily at the canister, providing an upgrade over stock but with less acoustic transformation than a full system.
What are the best aftermarket mods for the Yamaha MT-09?
Beyond exhausts, popular MT-09 upgrades include MT-09 frame sliders for crash protection and aftermarket windshields for improved wind management. An exhaust upgrade is often the first performance mod riders consider.
What exhaust adds the most horsepower?
A full exhaust system, which replaces the restrictive stock headers and catalytic converter, typically adds the most horsepower. Brands design these systems to optimize airflow from the engine head to the tailpipe, offering greater potential gains than a slip-on muffler alone.
Are slip-on exhausts worth it for an MT-09?
Yes, for riders seeking a lighter weight, improved sound, and a more aggressive look without the complexity and cost of a full system. They are a worthwhile upgrade, especially models like the KJTYSDM that use durable materials like stainless steel while keeping weight low.
The Bottom Line
The LeoVince LV ONE EVO Full Exhaust is the top choice for MT-09 riders committed to a comprehensive performance and acoustic overhaul. For owners on a tighter budget or those wanting only a visual and auditory tweak, the KJTYSDM Carbon Slip-On Muffler delivers a compact, lightweight solution. Before purchasing any exhaust, the single most important step is to verify it complies with local sound and emissions regulations to ensure your modified bike remains street-legal.
