    17742 is rated 3.7 out of 5 by 3.
    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.

    Rated 2 out of 5 by from Good kit bad match with jegs headers These headers were sold in a kit with thunder headers Flowmaster exhaust system. Issue 1. The collector and the front pipe are the same size. Issue 2. Header collector outlet inline with front cross member exhaust kit only had one pipe bent to fit around the front cross member. Issue 3. If your truck has a trailer hitch the rear of the exhaust and tail pipes will be all over it. If your going to attempt this kit at home on the ground look for something better. This was a perfect example of no one knowing what they were doing when they paired this kit up.
