I like the side exit also.
I had the headers powder coated and they still look new.
The GT40's just ran a "screen door" spring over the mufflers and bolted that to the chassis.
The spring gives flexability, doesn't transmit vibration and reduces the muffler vibrations.
Seems to work well enough.
My son fell on the ground laughing at them. Asked, "where did you come up with that idea from, Rube Goldberg?"
Then I showed him the pictures of the '40s. He stopped laughing. Out loud anyway.
I don't think Ferrari still laughs about them? They are in the back of the car, and he could get a really good look at them there?
