    17742 is rated 4.5 out of 5 by 2.
    Rated 4 out of 5 by from I just installed this kit on my '75 crew cab dually w/ 454 and Hedman headers . It did require me to extend the tubing about 3 ft on each side to reach the headers but that was expected. I ended up welding everything together and only clamping the tailpipes to the mufflers. Sounds pretty good, would recommend.
