Tubular Automotive Headers

Just found this thread.
Have been looking at a used set of these a guy has.
Had no idea they hang that low in the back, super low.
Guess I will have to bite the bullet and at some point get the 1 7/8 TTi’s. Darn!
But it won’t be soon.
Is this for a street car ? I ran Tubular W2 headers on my 73 Sport and they werent all that low .... my current 1 7/8 TTi's sit a little tighter to the chassis but not much . And its seems I remember the Tubulars being 2" primaries but I could be wrong .
