YAMAHA MT07 / XSR700 / R7 FULL STAINLESS EXHAUST SYSTEM (2014-2025)
Transform your Yamaha MT07, XSR700, R7, or Tracer 700 with our meticulously engineered full stainless-steel exhaust systems. Designed to replace the restrictive, heavy, and lackluster factory setup, our exhaust systems unleash the full potential of the CP2 engine, amplifying its iconic 270-degree firing rate for a commanding and distinctive soundtrack.
Beyond the significant performance improvements, our exhaust systems offer a range of muffler optionsand cerakoted finishes, allowing you to customize both the style, tone and volume to truly make it your own. Whether you’re aiming for a bold aesthetic or a signature tone, these systems ensure your bike stands apart from the crowd while improving its power-to-weight ratio.
Performance and Design
Our systems deliver:
Enhanced Exhaust Flow: Unlock the CP2 engine's full potential with increased torque and horsepower.
Lightweight Design: Shed up to 4.7kg compared to the factory exhaust system (stock system: 7.7kg).
Shorty System: 3.07kg
Alpha System: 3.15kg
Flanker System: 2.93kg
Each system is available in a brushed stainless finish, with optional black or bronze Cerakote finishes for select models. An included removable dB killer offers flexible volume levels, ensuring compliance with noise regulations while preserving the system’s signature tone.
Decibel Levels
No Baffle: ~98dB
Standard Baffle: ~95dB
Quietcore Baffle (Optional Extra): ~91dB
Quietcore Baffle: Available as an optional extra, this baffle significantly reduces volume for stricter noise compliance, though it slightly reduces top-end power. Systems include the standard baffle, allowing for three distinct sound profiles when combined with the Quietcore and no-baffle setups. Hear the difference in volume and tone between baffle selections here.
Fitment and Compatibility
Our systems are compatible with the following models:
2014–2024 Yamaha MT07
2016–2024 Yamaha XSR700
2021–2024 Yamaha R7
2016–2024 Yamaha Tracer 700
Note: While compatible with Euro5 models, these systems are not suitable for the Yamaha T7 due to frame design differences.
Performance Variability
Due to variations in restricted versions across regions and the wide range of intake and air filter options available, performance specifications are not standardized globally. However, the Kelpi CP2 full system with no baffle consistently delivers performance gains exceeding those of market leaders Akrapovic and SC Project, with only the Graves titanium system providing slightly better power outputs. Our standard baffle and no baffle options both provide horsepower improvements straight out of the box on stock tune.
Installation
Designed for quick and easy installation, the full system can be fitted in under an hour using basic hand tools (HEX set, sockets, wrenches, etc.).
System Includes:
Headers
Merge collector
Muffler
Fasteners and springs
Brackets
Removable baffle insert
For additional assistance, refer to our installation video or detailed instructions.

Installation instructions:
- disconnect the O2 sensor at the cable connection, this requires the frame side cover to be taken off and the connection is obvious by following up from the O2 sensor bung on the stock exhaust
- unbolt the two rear stock muffler mounting bolts that sit beneath your foot pegs on both sides with a 12mm socket with extender arm bar and joint
- Use that same tool to unbolt the header flanges mounting exhaust system to motor
- slip the kelpi headers onto the 2-1 merge collector and attach the springs to clamp them together
- place the headers onto the motor outlets (ensure the exhaust gaskets don’t fall out) and screw the flange nuts back on a couple of turns (but not torqued) so that the headers won’t fall off over the fitment
- bolt the included S bend bracket onto the right side rear stock muffler mounting point (snug but not torqued to allow the bracket to rotate still), noting that this will bend into place once tightened on the muffler side
- slip the muffler onto the merge collector and place the muffler in the desired position (some prefer directly under the footpeg, others like it to sit in as close to the swingarm as possible)
- rotate the s bend bracket so that a bolt can fit from the muffler through the S bend bracket (though the angle may not be instantly aligned) and tighten the bolt as S bend bracket shifts into alignment
- once the rear mount is torqued, add springs from the muffler to merge collector
- torque the engine header flange nuts at the top of the exhaust system
- screw the O2 sensor into the new exhaust system and reconnect the plug on the other end of the O2 sensor
