Hooker Blackheart Long Tube Headers for the C7 Corvette!

The exhaust manifolds are removed from the bottom as well.

The stock manifolds are not too bad, they are not logs but are almost like short tube headers.

The stock manifolds have a smaller internal diameter than the headers.  They also make a tight bend right out of the exhaust port which inhibits flow.  The primary advantage of the long tube headers is that they take advantage of pulse tuning.

The headers load up from the bottom.  It’s a tight fit but they can be wiggled up there. We installed the driver’s side first.

  1. With the future intake manifold, will you also install a larger TB to match too?
    As for tune, HP Tuners? Or something else?

    1. We are keeping the stock throttle body for now. We will be using Church Automotive Testing for our Tuning with HP tuners.

  2. I have a set of Hooker Blackheart Shorty headers for my 08 Mustang sitting on my workbench. The flange is warped on one of them, I am dropping them off at a shop to be sanded flat this week.

    Did you guys have the same experience? Or check the flanges for flatness?

    1. It’s kinda weird because they are water jet cut. Not likely to warp as is possible with plasma or Laser. They are pretty thick to warp from welding as well.

  3. What are you going to use for plug wires ? My ppg on the driver side in the back was hard to get back on I think I might need 45° plug wires.
