Back in the days when gas was around $1.50, I had an '85 Ford w/ a 351W. I put the 50 series, 2 chamber on it w/ a single 3" and it sounded NICE coming out the back. It still had the cat. converter, so it was tamed down a little bit.
I could hear it in the cab w/ the windows down, but isnt that the point of getting an exhaust system like that?
Hated to get rid of it, but 6 MPG was not the most economical vehicle LOL
