Just wondering if anyone has any suggestions, I want to mod the exhaust in the car MKII Turbo Manual. I think I just want to change from the CAT back, or should I change the CAT as well? I contacted APS and they told me that the exhaust system is only offered in the Phase II system, and is a complete exhaust system from the turbo back. I see no point in getting this as I am going to I want to get the edit a couple months after the exhuast is put in. Furthermore they said, the Ford’s are very temperamental when it comes to modifying without some form of ECU device to tune for the added modifications. So they recommend that I have the vehicle tuned when fitting any extensive modifications to airflow/exhaust flow. So does this mean that I have to get edited at the same time or is there a system where I don't need an edit staright away? Sorry, if this sounds stupid, I am still learning.
