Came with my TTI system, a set of Dynomax 17748 super turbo mufflers.

2.5" offset inlet, center outlet.
Case Exterior Length (in.): 20.000 in.
Overall Length (in): 25.500 in.
Thickness (in): 4.250 in.
Width (in): 9.750 in.

I ran them on a couple drives and decided they were too quiet and swapped for Ultra Flo's.

These have a very mellow, deep tone and are ideal if you want a classy, subdued sound with no drone.

They are like new, no rust dirt or damage. Have been painted with hi-temp gloss black paint.

$110 shipped.
Trade interests:

Quality set of spark plug wires for small block stock distributor
Black steering wheel 3-spoke for '67 b-body
Nice/fancy black floor mats for 67 b-body

Idle sounds almost identical, more bark at mid to full throttle. Sounds raspier, the super turbos are smoother.
