I installed the same thing on my 73, the pipes are nice and mandrel bent and fit pretty good for a driveway install. My passenger side does not point straight out either. And the flanges are terrible, throw them away and buy a hooker solid flange adapter to weld to the pipe. Mine is 2 1/2" the Mufflers are pretty loud with The Hooker headers. But for the price it was good and later I will upgrade the mufflers.
