Observe that all our exhausts and mufflers are bolt-on, and are made to fitstockvehicles. We can not take responsibility for any aftermarket modifications or additions made to any vehicle.
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 manufacturers recommended settings.
