When dealing with the MazdaSpeed 3 especially, the downpipe is one of the most sensitive elements. When replacing the downpipe on the MazdaSpeed three, it is extremely important to choose the appropriate brand. In our experience, we have in fact seen the turbo get damaged when the appropriate downpipe wasn’t utilized. We have discovered that the Cobb 3” Downpipe for the MazdaSpeed three is the greatest alternative.

Whenever you set up a mod that significantly increases airflow (such as a downpipe), it is critical to also tune your engine for this enhanced airflow. If you never, the ECU will still believe that it has the stock downpipe and will inject fuel accordingly. This signifies that there is not enough fuel becoming injected to match with the increased airflow that is truly going into your engine.
