i have a 96 formula, im starting to get codes for cat emissions etc. and so i want to put headers on my car and get rid of all 3 cat's currently. do i have to get different 02 sensors when i get headers? what is the best brand of headers that will get me the MOST power? thanks for any help gentlemen.

 

You want Lt's or shorties? or Mid length.

 

If you don't have emissions requirements and your car is at stock ride height, then I would consider long tube headers with the off-road y-pipe or a true dual setup. There may be some confusion on your part though, from the factory, your car only has two cats. The 93-95 OBD-I style cars had a single cat. With the headers, you won't need different 02 sensors, although it has been shown in the past that coated headers upon initial startup are rather hard on the 02 sensors and can damage them.
