Upgrading your Yamaha MT-07's exhaust system can transform your riding experience. But with so many options available, how do you know which system delivers the best performance, sound, and value? The answer lies in understanding what makes a quality stainless steel exhaust system stand out—and why the MT-07 deserves nothing less than premium components.
The Yamaha MT-07 has earned its reputation as a versatile middleweight motorcycle that balances power, handling, and affordability. However, the stock exhaust system often restricts the bike's full potential. A well-designed aftermarket exhaust system can unlock hidden horsepower, reduce weight, and give your MT-07 the aggressive sound it deserves.
This guide explores what makes stainless steel exhaust systems the ideal choice for your Yamaha MT-07, how smart exhaust technology enhances performance, and the key features to look for when selecting an upgrade.
Stainless steel has become the material of choice for high-performance motorcycle exhaust systems, and for good reason. This alloy offers a unique combination of durability, heat resistance, and aesthetic appeal that other materials struggle to match.
Durability That Lasts
Stainless steel exhaust systems resist corrosion far better than mild steel alternatives. Rain, road salt, and temperature fluctuations won't cause premature rusting or deterioration. This means your investment continues to perform and look great for years, not just months.
Heat Management
The MT-07's parallel-twin engine generates significant heat, especially during spirited riding. Stainless steel maintains its structural integrity even at extreme temperatures, preventing warping or cracking that can occur with lower-grade materials.
Weight Savings Without Sacrifice
While not as light as titanium, stainless steel strikes an excellent balance between weight reduction and strength. A quality stainless steel system can shed several pounds compared to stock, improving the MT-07's power-to-weight ratio without compromising durability.
Visual Appeal
A polished stainless steel finish gives your MT-07 a premium, race-ready appearance. Unlike painted systems that chip and fade, stainless steel maintains its lustrous finish with minimal maintenance.
Modern exhaust technology has evolved beyond simple pipe routing. Smart exhaust pipe design on a motorcycle considers multiple performance factors that work together to optimize engine output.
Improved Gas Flow Dynamics
The diameter and shape of exhaust pipes directly affect how quickly combustion gases exit the engine. A 51mm front tube—standard on many performance MT-07 systems—provides optimal flow for the bike's 689cc engine, reducing back pressure while maintaining necessary exhaust velocity for strong mid-range torque.
Scavenging Effect
Properly designed exhaust systems create a scavenging effect where exiting gases help pull fresh air-fuel mixture into the combustion chamber. This improves volumetric efficiency, resulting in measurable power gains throughout the rev range.
Weight Distribution
Strategic placement of exhaust components affects the motorcycle's center of gravity. Moving weight closer to the bike's centerline improves handling response and stability, particularly during aggressive cornering.
Sound Tuning
Beyond performance, exhaust design shapes the acoustic signature of your motorcycle. Quality systems produce a deep, throaty note that announces your presence without being obnoxiously loud—perfect for both track days and daily commuting.
Not all exhaust systems deliver equal benefits. When shopping for your MT-07 upgrade, several key features separate exceptional products from mediocre alternatives.

A quality exhaust system should install without extensive modification to your motorcycle. Look for systems that include:
All necessary gaskets and hardware
Clear installation instructions
Compatibility with stock mounting points
No cutting or welding required
Realistic expectations matter. A complete stainless steel exhaust system for the MT-07 typically delivers:
3-5 horsepower increase at the rear wheel
2-3 kg weight reduction compared to stock
Improved throttle response throughout the rev range
Enhanced mid-range torque for better acceleration
MT-07 owners face a common decision: full system or slip-on muffler? Each approach offers distinct advantages depending on your goals and budget.
Full Exhaust Systems
A complete system replaces everything from the engine's exhaust ports to the tail pipe. This comprehensive approach typically includes:
Front exhaust pipes (headers)
Mid-pipe or link pipe section
Muffler canister
Benefits include maximum performance gains, cohesive styling, and optimized gas flow throughout the entire system. However, full systems require more installation time and typically cost more than slip-on alternatives.
Slip-On Mufflers
Slip-on systems replace only the muffler section, connecting to the stock mid-pipe. These offer:
Easier installation (often 30 minutes or less)
Improved sound with modest performance gains
Lower cost
Reversibility if you want to return to stock
For MT-07 riders seeking maximum performance, a full system with 51mm front tube and stainless steel construction delivers the best results. The increased pipe diameter from the headers forward allows the engine to breathe more freely, unlocking power that slip-ons alone cannot achieve.
One major advantage of stainless steel exhaust systems is their low maintenance requirements. However, some basic care ensures your system maintains its appearance and performance.
Regular Cleaning
Road grime, chain lube, and exhaust residue can accumulate on your pipes. Clean your exhaust every few weeks using:
Mild soap and water for general cleaning
Stainless steel polish for removing discoloration
Soft cloths to prevent scratching
Inspection Points
Periodically check for:
Loose mounting bolts or clamps
Exhaust leaks at gasket points
Physical damage from road debris
Heat discoloration (normal but can be polished if desired)
Heat Cycling
New stainless steel exhausts often develop slight discoloration after the first few heat cycles. This is normal and doesn't affect performance. If you prefer to maintain a pristine appearance, high-temperature exhaust wrap or ceramic coating can minimize this effect.
Exhaust regulations vary by location, making it essential to understand your local requirements before purchasing. In the United States, the EPA regulates motorcycle emissions, while individual states control noise limits.
Federal Regulations
The EPA requires street-legal motorcycles to maintain their emissions control equipment. For the MT-07, this primarily means the catalytic converter. Some full exhaust systems include a catalytic converter, while others are designed for "off-road use only."
State Noise Limits
Most states limit motorcycle exhaust noise to 80-96 decibels, measured at specific distances and engine speeds. Quality aftermarket systems designed for street use typically fall within these limits while still providing an enhanced sound over stock.
Solution for Compliance
Many riders opt for systems with removable baffles or dB killers. These allow you to:
Reduce volume for street riding and noise-sensitive areas
Remove restrictions for track days and off-road use
Maintain legal compliance when required
Before purchasing, verify whether your chosen exhaust system meets local regulations or includes components necessary for compliance in your area.
Exhaust modifications typically don't void your entire warranty, but Yamaha may deny warranty claims for engine or exhaust-related failures they determine were caused by the aftermarket system. The Magnuson-Moss Warranty Act prevents manufacturers from voiding warranties simply because aftermarket parts were installed—they must prove the part caused the failure.
While not strictly required, a fuel mapping adjustment optimizes the performance gains from your new exhaust. The MT-07's fuel injection system can adapt to some degree, but a professional tune or aftermarket fuel controller ensures proper air-fuel ratios, maximizing power while preventing potential lean conditions.
Sound increase varies by system design. Expect approximately 5-10 decibels louder than stock with most systems. For reference, stock MT-07 exhaust measures around 85-90 dB, while most aftermarket systems range from 95-100 dB. Systems with removable baffles offer volume control.
Yes, most MT-07 exhaust systems are designed for DIY installation. Basic mechanical skills and standard tools are sufficient. The process typically takes 1-2 hours for a full system, less for a slip-on. Ensure proper torque specifications on all fasteners and check for leaks after the first ride.
These designations refer to different muffler designs inspired by various manufacturers. "AK" typically indicates an Akrapovič-style design, "AR" references Arrow-style systems, and "SC" suggests an SC-Project-inspired look. Each offers slightly different sound characteristics and aesthetic appeal, though performance differences are minimal among quality manufacturers.
Upgrading to a quality stainless steel exhaust system represents one of the most effective modifications you can make to your Yamaha MT-07. The combination of weight reduction, performance enhancement, and improved aesthetics makes this upgrade a worthwhile investment for riders seeking more from their motorcycle.
When selecting your exhaust system, prioritize build quality and proper fitment over price alone. A well-engineered 51mm stainless steel system with complete front tube, link pipe, and muffler components will deliver years of reliable performance and satisfaction.
