Thanks! The Tick is coming along... doing body work right now while waiting on availability of parts and funds to buy parts.

The SVT header requires you to convert the rest of the exhaust that is not replaced by a CAT back.

If you go with a SVT header you need: SVT header, SVT CAT, SVT Flex, SVT Oil Dipstick Tube, SVT PS Line (or bend your current line), EGR block off plate w/tune or EGR bung welded in.

a Tune is recommended in general with this because you can lean out at WOT. not sure any one had damaged the motor but you would lose power.

I believe the stock SVT CAT is higher flow then Zetec stock CAT. Your gains from this conversion is not from the change of the cat rather the change to a full length 4-2-1 header that the SVT is.
