Hey Guys just curious to see who has put the mil's on ther 97-Present ford trucks, I Know that the one I purchased from a Mustang shop a year ago seem to work fine, I just wanted to know if other people have used other types of "Syms"

Thanks yall'

You don't need mil's because you can't cut all 4 cats off , because your truck want run right. But you can cut the back 2 off thats the big ones. If you cun just two off your truck will run fine also it will be loud. So you want need the mil's. Mustang's you can cut all the cats off and in will run fine , but your check engine light will come on. So you need mil's for mustangs. (best friend has '99 mustang with no cats and mil's)

 

another member ( 98 I think ) posted that you used this if you took off the 2nd set of cats, for bypassing the 2nd bank of O2 sensors.

Are these what you are refering to ?
