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.
