The Mud Edition is one of the most exclusive exhausts we have released. No expenses were spared in developing what might be the most refined top-tier exhaust for ATVs on the market. We genuinely believe that this is the highest quality exhaust system money can buy.
Observe that all our exhausts and mufflers are bolt-on and are made to fit stock vehicles. We can not take responsibility for any aftermarket modifications or additions made to any vehicle.
We always recommend using a Fuel Tuner (EFI-tuner) combined with any of our 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.
