OK.. now i did all that they talked to a regional rep.. and he says my warrenty is voided to..that means the FORD told me my warrenty is void.. so.. i still have no proof that my intake caused the problem however i still have a voided warrenty on my cat.. matter of fact the regional rep can't be overturned...at least they told me that when i had to call michigan.. he says "call the epa maybe someone from there can help you pay for it".. so now that this is all said and done.. im not gonna pay $800 for a new cat.. and thas that..i will just be running with a gutted cat for a while i guess..until i get a header.. and i will be catless then.. so ford can kiss my a$$..
