1 7/8 Header Selection

The 5303 are adjustable headers as I recall.
I have had nothing but trouble with that design
on street cars with them leaking at the joints and
the noise made me crazy!

As I recall, the 5304 are a copy of the 1 3/4 race car header
that were built on the same jig as the race headers without
the slip joints and a collector for a street application. I had a
involvement back it those days with Hooker in their California days
many years ago. The tube length worked pretty without additional
length installed unless the car was very heavy.
