APX/AL (where AL stands for Aluminium). It’s an all-aluminum modular construction where RJWC uses CNC machined brackets on all critical points where they know welds may be a weak point. The whole system is CAD drawn with extruded aluminum cans. The shape of the cans is their own, and not any over the counterpart that you can buy per inch. All aluminum parts are anodized, new logo, new everything.
Cans
- 6061 Extruded and anodized aluminum
- 6061 Anodised brackets and flanges
- Yellow zink plated and Stainless screws and nuts with lock washers
- New inner cores (compatible with current core wrap)
- Fully serviceable by user/owner/rider/workshop
- Casted stainless intake flanges (this part in itself is a jewel)
Included in package
- Everything needed to mount the system on your ATV
- Lambda bung for your lambda probe/oxygen sensor
Fuel Tuner
RJWC always recommends using a Fuel Tuner (EFI-tuner) combined with any of their exhaust systems. This is to prevent the engine from running lean, which can damage your engine. To ensure the 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 reflashing 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.
