2014-2021 XSR900 / MT09 FULL STAINLESS EXHAUST SYSTEM
Few people feel the first generation Yamaha Crossplane 3 motor is lacking power straight out of the box, but there’s widespread consensus that the exhaust note should be more noticeable than the triple induction whir when riding. Our full stainless systems adds a lot of attitude into the tonal mix, whilst increasing torque, and reducing weight by 4kg or more depending on the muffler selected. The Kelpi CP3 exhaust system on the CP3 motor increases exhaust flow, allowing for performance gains, with further gains noticed once the air fuel ratio is optimised. For making the absolute best power that can be made on these motorcycles across the rev range, an exhaust and intake specific ECU flash or custom dynotune is recommended. It is up to you whether you deem a retune a priority, and we have plenty of clients who run our exhaust systems without retuning their bike, with particularly satisfying results when running the standard baffle. If you would like to discuss our mail-in ECU service which features tunes specific to our systems with most intake modifications currently on the market, please email us.
Made from tig welded 304 stainless steel, our CP3 systems come with several muffler and baffle options to suit you and your bike’s styling and tastes. The Shorty is our reverse cone muffler, offering a more classic styling, with a low-mid bark of resonant note. The Flanker is visually more modern with a carbon end cap and mesh grill, offering the lightest weight with a deep burble note that's great on triples. The Alpha is slightly longer, has a more moderate volume and a curved hydroformed structure which works across the MT and XSR models visually. With a quick-change end-cap baffle, the Alpha's volume can be brought lowest, with a smooth tonal characteristic that makes it a pleasure to ride with. We also offer the Shorty and Alpha in satin black Cerakote or burnt bronze Cerakote finishes, allowing you to tailor the visuals to suit your ride. In terms of baffles, the standard baffle that's included on all systems works nicely on the stock tune whilst dropping volume between 3-5dB. The Quietcore baffle offers more significant volume reduction at the expense of some top end horsepower. This can be particularly useful for testing and roadworthy inspections.
- Fitment for 1st Gen CP3 Models (2016-2021 XSR900, and 2014-2020 MT09 etc)
- Setup includes headers, collector, link pipe, muffler, fasteners, springs and standard baffle
- The Quietcore baffle option provides both the quietcore baffle and the standard baffle.
- Can be installed with basic hand tools in under 1 hour (HEX set, sockets & wrenches etc)
Install Instructions can be found in the additional info tab.

INSTALL INSTRUCTIONS:
To install, begin by fitting the link pipe onto the headers whilst off the bike (you may need to twist these to get the slip joint snuggly seated). From there, disconnect your o2 sensor and unbolt the stock exhaust. Begin installing the new system with a note to ensure you keep the stock exhaust gaskets sitting into the motor. The best tip for this is to use a small dab of grease on each gasket which will be enough to stick it to the motor whilst you’re fitting the headers in. From there, screw on the header flange nuts ensuring that the nuts are fitted but not tightened (back them off one or two turns from snug). Slip the link pipe onto the headers, then the muffler onto the link pipe (springs will be placed later). This is the point where you want to rotate your link pipe generally counter clockwise so that you can set where you want your muffler to be positioned - you want it to be sitting in nice and close to the swingarm and rear tyre, not sticking outwards underneath your foot peg. Once you’ve got the position you’re happy with, bolt up the S bend bracket to the original stock rear muffler mounting point and bolt that to the muffler. It’s important not to torque your headers or set the springs before setting that rear position, but once your rear mounting bolts are done you’re able to torque your header flange nuts, and then begin adding the springs to the system. The tapered smaller length springs are for the muffler to link pipe, and the linear longer springs are for the merge collector to link pipe. From there, connect your o2 sensor and you’re finished! After a couple of minutes running the protective layer of oil will have burnt off, and after your first ride the exhaust will take on a golden colouring. As the stainless is brand new, the first time it colours up from rising will always be the most vibrant, so I’d recommend taking it out for a solid half hour ride at a minimum to get as much colour on the pipes as possible (note: I am not condoning illegal behavior and speeding, it’s just a note).
NOTE: Do not turn your motorcycle on or start the bike until you have reinstalled the o2 sensor. Failure to do this will result in a ‘check engine’ code being thrown which will cost $50 for yamaha to reset the code if you don’t have your own OBDLink scan tool and know-how.
