This product has been designed to fit both manual and CVT transmission vehicles. The appropriate product must be purchased to ensure the correct transmission bracket is included.

This downpipe cannot be used with the stock ECU programming. It is highly recommended that the customer is able to retune the vehicle’s ECU after installing the downpipe. Power gains will vary depending on the type of ECU tune that is applied to the vehicle.

This downpipe will require additional ECU tune and is not compatible with the stock tune. Upon shipment of these units we will have a tune specific to this downpipe and it’s combination with any other available Mishimoto products.

Thanks Nasioc!
