Hooker #5303 headers for street Ok?

These are a race oriented header with slip fit tubes going between the collector and the head pipes. I own a set of these and would not recommend on a street oriented car. I believe the tubing might also be lighter gauge on these than regular street headers. Collectors have no flange for mating to exhaust system, although band clamps could be used. One tube on each bank goes through the wheel well. Power steering can not be used with the 5303. These are a tunable race header, unless you own a set they may prove difficult to obtain as they have not been made for years.

For what it's worth, my W2 head 408 stroker uses 15/8 to 1 3/4 stepped headers in my street Dart. Dynoed at 547hp.

It is my opinion you would be better off with a good quality set of street headers. I'm not saying the 5303 cant be used on street, I dont feel it is the proper application.
