Not so.. the Super 40 has a larger case and is not quite as loud as the 44. Interior sound is also a little lower. Flowmaster states to use the Super 40 on high horsepower applications.
They made an Off Road version of the Original 40 and Super 44 but they no longer make those.

x2 I tried it on my stock cracked manifold. held for about 15 minutes, but after it warmed up it blew out. Then I tried running a few beads with my mig on it, and that held for about a month, then cracked again. But now I'm very happy with my Pacesetter long tube header/downpipe assembly
