So for the last 12 months, we’ve been working hard. We’ve started from scratch to develop what will be, in our eyes, the perfect SxS/UTV exhaust. This is not a current ATV exhaust we’ve managed to fit an SxS/UTV, this is built from the ground up to be a specific, purpose-built Side by Side exhaust.


It’s the RJWC Powersport APX/AL (where AL stands for Aluminium). It’s an all-aluminum modular construction where we use CNC machined brackets on all critical points where we know welds may be a weak point. The whole system is CAD drawn with extruded aluminum cans. The shape of the cans are our own, and not any over the counter part that you can buy per inch. All aluminum parts are anodized, new logo, new everything.

Also, you can buy header pipes for the Turbo models as well. All piping is as per usual, stainless.


We've sent out to make the very best and most exclusive SxS exhaust we could come up with. And, since it’s in some way modular, we have more up our sleeves.


Well, yes, it will. We’ve spared no expenses in designing it, all parts are purpose-built and custom made for this exhaust with one thing in mind, to make the very best exhaust for side by side on the market.

We always recommend that you use a Fuel Tuner (EFI-tuner) combined with any of our exhaust systems. This is to prevent the engine to run lean which can damage your engine. To ensure correct air to fuel mixture make sure you follow the Fuel Tuner manufacturer's recommended settings.

An option would be a full EFI Tune with re-flashing or similar. Problems with the exhaust due to the engine not running correctly are is not a valid warranty claim.

If your machine differs from the base model you may need to add another tune, turndown pipe, etc, to make things fit and work correctly.
