headers for a 318

what the hell is that thing???


It's a 120 degree mandrel bend 2 1/2" pipe welded to a the 340 flat flange down pipe stub. If you use my 340 driver manifolds on a 67 and up A body this 120 degree adapter help you get past the torsion bar. Otherwise you'll pay the muffler shop to crush regular pipe to try and get enough clearance above the torsion bar.
Pics show the 120 degree piece helps clear the torsion bar. There's no restriction, there's a sharp turn but it's straight through (as you can see) with no crushed pipe.
