Please do some research before giving others advice.
Catalytic converters need to reach and maintain a certain temp to work. That is why they are positioned close to the engine. Moving them further from the engine renders them useless.
X2 on this. there may be a reason that the zetec and svt focus both regularly perform BEST in open header configuration on the dyno and at the track. the less restrictive you can make the exhaust the more power you will make.
