I am new to the shorty headers. I know they are not a large gain in HP. I am just looking for Milage and sound. Do most the shorties fit the stock exhaust? I would love to do long but I do not have the money to do the whole system at once.

I have the Gibson shortys on mine and they made it sound a little better but not much. Putting long tubes on in a week or two.
The shortys bolt right up to the stock set up.
