The APX Single exhaust is built and assembled in our shop located in northern Sweden using only the highest quality materials. The cans and tubes are crafted from durable extruded aluminum, and all other aluminum parts are CNC machined out of 6061 billet block to ensure superior quality and long-lasting performance.

The exhaust features precision TIG welding with a high-quality filler rod and mandrel-bent, thick tubing to provide maximum airflow and reduced back pressure. It produces an incredibly deep and clean sound that is sure to turn heads on the trails.

The APX Single exhaust comes with a spark arrestor and all necessary mounting hardware, making it easy to install on your stock vehicle. Additionally, all our mufflers are repackable and compatible with RJWC Corewrap, ensuring long-lasting performance and easy maintenance.

Please note that the APX Single exhaust is designed to fit stock vehicles only and may not be compatible with aftermarket modifications or additions.

Fuel Tuner

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.
