Just thought id clear things up. Can 99-04 mustang gts have long tubes on an automatic tranny without modifing header?

I am waiting on an order I made for MAC LT headers. From the research I did, they were the best for the $ that fit Automatics straight out of the box. This is from what I read though, I havent recieved them yet so really can't tell you from personal experience. If you want to spend some more cash, you can also go for Hookerswhich are very good.

i also heard from a friend that owns/works at a mustang shop that MAC longtubes are good for autos, and he said he likes installing those the best on autos(best fitment)
