Well im planning on putting a really beefy automatic in my car and i was wondering about my headers. My hpipe is adjustable (mac) and the headers are mac longtubes. It came off my friends car that had a 5speed in it but then went to a c4 and seem to fit fine when we took them off to put them on my 5speed. Is there a way to tell if these are aod headers? Trying to make a last list of what i need to repalce for the conversion thanks
