Important
If your vehicle deviates from the base or standard model—whether due to an equipment package, special edition, higher trim level, or aftermarket addons—it's crucial to reach out to us before finalizing your purchase. Our parts are engineered primarily for the base model, unless explicitly stated otherwise.
The reason we emphasize this is that even minor modifications or variations from the standard model can affect the compatibility of the part you're interested in. These differences may include changes in dimensions, mounting points, or even the materials used in your vehicle's construction. As a result, what fits the base model perfectly may not be suitable for a modified or upgraded version of the same vehicle.
Contacting us in advance allows us to assist you in verifying the compatibility of the part with your specific vehicle model. This proactive approach can save you not only time and money but also the inconvenience of dealing with returns or exchanges later on. Your satisfaction is our priority, and we aim to ensure that the parts you purchase are a perfect fit for your vehicle.
Fuel tuning
The use of an aftermarket performance exhaust requires a crucial step - EFI tuning. RJWC Powersports exhaust systems must be accompanied by a proper re-flashing or use of an EFI Tuner to prevent the engine from running lean, which can result in engine damage. To guarantee a correct air to fuel mixture, make sure to adhere to the manufacturer's recommended settings for your fuel tuner.
Neglecting to properly tune the engine using an EFI tuner when using an RJWC Powersports exhaust will void the exhaust warranty. Any problems arising from the engine not running correctly, such as a lean condition or incorrect air/fuel ratio, will not be considered a valid warranty claim.
Please note that if your vehicle differs from the base model, additional modifications such as a different tune, turndown pipe, or other adjustments may be necessary to achieve a proper fit and optimal performance. All RJWC Powersports exhausts are designed and tested on stock-equipped vehicles.
Repacking
Why Repack?
To maintain optimal performance and sound quality, regular repacking is crucial. Over time, packing material degrades due to heat and vibrations, affecting both sound and horsepower. Inspect and likely repack every three months with regular use; avid riders may need to do so more frequently to ensure longevity and keep your warranty intact.
RJWC Repacking Kit
Our kits include a needle-felt glass fiber mat and stainless mesh, designed for high-temperature resistance and durability.
Repacking Process
Our bolted mufflers simplify the repacking process. Just open, remove old packing, wrap the new mat around the core, seal with high-temp silicone, and bolt back together. Always wear gloves for protection.
Longevity Tips
Stick to a regular inspection and repacking schedule as recommended in your user manual. For best results, use RJWC Repacking Kits.

Just as good as th first set
They are good to keep the volume down but i don't like the sound when i use them
Great Product. if you looking for quiet sound in your machine this is the best option
Everything works great,but I don't find any stickers in a box
I'm satisfied with the soundproofing kit, but I'm unhappy that I wasn't informed about the additional tax charged by FedEx.
Perfect SOUND with this ekstra instalation 😍
I really like the sound of the exhaust on my xp1000. But with using it to plow snow in the neighborhood not a real great thing...😂 this tames it just enough to still be rowdy and let your presence known, and at lighter throttle you can "try" to sneak around. Makes yard work more pleasant.
Great fit and does what it should quick shipping and quality
It is great and keep the exhaust sound but with a refined tone.
Great product
Best performance, nice sound
did exactly what I wanted to
It does what it's supposed to. Easy to install.
Sounds deeper not annoying anymore
Best
APX quiet cores work very well for those guys trying to have a good exhaust note but keep a low profile on the trails, cuts sound down quite a bit. Sounds good still just less deep note in it. Still had a great raspy aggressive sound just at a lower tone. Idle doesn’t sound amazing with them in but every other throttle position sounds nice!
Fantastic product
Great welding
I like it
Built very well but didn’t quiet it down much.
I feel for the price and the volume of the single and or Dual exhaust these should be included in the original kit. These offer a much more tolorable sound while keeping the chop and good stuff. If you dont run them and have no hearing protection good luck. I do think they could do a little more finishing work on the tail end of the horn potion that would make it look better from the back side. These do restrict the exhaust some but doesn't seem to be enough to notice a power drop. If you have the dual version I'm sure it really doesn't slow things down too much to notice. A lot of times its hard to drop sound levels without adding a restriction.
Quality as always, quicker shipping then most company's from USA and it comes from Sweden.....hard to beat
Very nice product but not quiet enough for the Dutch market
