I built a low budget 5.0 conversion 82 Mustang. 78' 302 w/mild rebuild and c4 trans. I have $1300 invested so far including the price of the car ($200). My question concerns exhaust flow. At the time of the build I could only afford a set of factory 5.0 shorty headers and a friend donated a used exhaust system off a 94' 5.0 w/cats gutted out by me (nasty job)and glasspack mufflers stopping before the rear. How much would installing a true 5.0 h-pipe/or x-pipe benefit over the gutted cat system?

I think the first thing to do is get rid of those factory headers. They are extremely restrictive. If you look at the tube right at the flange you will see how they are dimpled inward and restrict flow right out of the exhaust port. That would be priority for me. ------------------

Thanks for your input. I'm just looking for the best $ per hp gain without going to long tubes. What company do you prefer or recommend? BBK,MAC,Headman?

I love my JBA shorties. They are very pricy but if you can find a good used set like I did you will be very happy. I paid 110 shipped for my set and they were like new. Make sure you buy a set with a 1 piece falange, if you dont and you have to remove them and reinstall them they are a pain. They tend to warp without the falange so I would not recommend buying a used set without the falange. I would definitely go with an X or H pipe also. Even a gutted cat will restrict air. Basically anything not smooth on an exhaust restricts air. I have the Bassani X pipe with no cats and with the headers I noticed a bunch of difference.

I'm not knocking long tube headers or anything and know they make more power. The thing is I drive my stang everywhere and at some point the starter will fail and I don't want to perform open heart surgery to change a starter(header removal). Just looking ahead. Looking for opinions on trials of others using shorty headers.Thanks
