HookerHooker Ls Exhaust Manifold, Natural

These were installed into a 1972 chevy c/10 with a 5.3 conversion . They fit with plenty of room between the frame rails excellent for this particular application. The pipe flanges that come with are just flanges and you have to weld pipe to them and hooker recommends you have a welder for stainless steel welding...and in my case i dont so i made my own design for the pipe i flattened the pipe (with a pipe bending machine) and used a walker exhaust gasket part # 31334 . I used factory style gaskets to mount to the head.
