No, it had duals. The first three exhaust-port tubes came together in one collection bucket and the back three came together in another. Hence, two glass packs and two exhaust pipes leading out the side a la the Challenger TA. Very advanced technology for 1972. I got the idea from an article I saw in Motor Trend or something that was titled, "Maverick: Tricks with a Six," and since somebody was selling the headers, I, naturally, had to try it. It didn't do a lot for performance, but the sound was impressive.
