Lol how old is that article. They dont even make those 3 tubes any more. My three tubes from headman were way better than any manifolds and a few of the four tubes i tried.
Fyi hooker 1 3/4 long tubes are not the same price as the 3 tubes about 100 bucks cheaper and only a few hp down.
Just depends if the cost and clearence are worth it for the four tubes.
