wrong..
since header on our stock 3's has a cat converter in it, its longer then just the obx header itself. you need the mid resonated pipe from OBX with it, or get a muffler shop to make you a flex pipe. Also you have to get new a spacer for secondary o2 bung not to cause a CEL, since now you will be running cat less..
any other info plz let me know, i installed plenty of headers on mazda 3's
