One of the bad sides about the FCs in the States is that they have the pre-cat cat which further reduces airflow. So what we've got here is a solution for that: a downpipe that will go straight down from turbo to your main cat (if you have one). Just glanced on Mazdatrix and they retail for $299 plus shipping so if anyone wants to save over $100 and get this one including shipping then let me know
