does anyone know when there might be a header with cat or aftermarket cat replacement for a 99' 1.8. Mazda wants like 3 bills for a replacement cat and I'd rather get a header or header with cat built in or cat alone, than to shell out 3 bills for an oem part.I have looked all over and if anyone can tell me if they even know if somthing is on the drawing board for something to replace the main cat underneath the header other than a header to eliminate the cat. If you know nething please tell who might be making one and when it might be released
