YAMAHA XSR700 FULL STAINLESS EXHAUST SYSTEM (2016-2025)
Replacing the stock exhaust with a Kelpi full stainless XSR700 system is one of the most impactful upgrades you can make. Designed to enhance the natural tone of Yamaha’s 270-degree CP2 engine, our system unlocks a deeper, throatier exhaust note while improving overall flow and shaving off over 4.5kg of weight. That means sharper throttle response, more usable midrange, and a serious improvement to the bike’s power-to-weight ratio.
Whether you're chasing a retro-inspired look or just want something that doesn’t sound like a sewing machine, our modular system allows you to choose your preferred sound and style. With multiple muffler options and select Cerakote finishes available, you're able to tailor the visual and tonal identity of your XSR700 with precision.
Performance & Sound
Each system brings the CP2’s character to life with a richer tone that finally does the engine justice. The system includes our standard baffle (pre-installed), with the option to swap in our Quietcore insert for more subdued output on long rides or early commutes.
No baffle: ~98dB
Standard baffle (included): ~95dB
Quietcore baffle (optional): ~91dB
Construction & Weight
Built from TIG-welded 304 stainless steel, each component is designed for longevity and performance. Mufflers feature multi-layer packing (perforated tubing, stainless mesh, fibreglass, and cotton gauze) to manage tone and minimise fatigue.
Full Shorty System: 3.07kg
Full Alpha System: 3.15kg
Full Flanker System: 2.93kg
Factory Exhaust System: 7.7kg
Select models are also available in black or bronze Cerakote for increased corrosion resistance and a stealthier finish.
Fitment & Installation
Compatible with all 2016–2025 Yamaha XSR700 models
Includes: headers, merge collector, muffler, all fasteners, springs, brackets, and a standard baffle insert
Installs in under 1 hour with basic hand tools
Tuning Guidance
This system runs perfectly on the stock ECU with the included standard baffle. ECU tuning is only recommended if running no baffle and combining the system with aftermarket high-flow filters or airbox mods.
Why Choose Us
Significant weight reduction over stock (up to 4.8kg saved)
Full 304 stainless construction, hand TIG-welded with clean serviceable joins
A balanced exhaust note that brings the CP2 engine to life without excessive volume
Customisation & Support
From muffler styles to finish options, we offer plenty of room to make the system your own. Whether you're after a subtle brushed stainless or a blackout bronze Cerakote setup, we’ll make sure it suits your build. For anything custom or specific, just flick us an email and we’ll get you sorted.

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
