    Rated 5 out of 5 by from Good kit I’ve had this kit on my truck for a few months now. I have the low tones and at idle it’s raspy and deep but not too loud and at WOT it’s loud and claps. All in all a good kit. All I had to do was move the temp gauge piece. The headers took a little bit of effort to put one but the pipe went right on. The only complaint I have is the clamps and gaskets were kinda cheep good ones didn’t cost much so it was worth it!

    Rated 5 out of 5 by from AMAZING! GREAT SOUND! Hello, I am Kenneth, I live in Kentucky and I bought these, the kit was amazing, but a few odds and ends needed to be changed, one being the temp gauge plug in the side of the block needed to be honed out, and the pipe was a tad to tight, but it was alright and bearable, nonetheless it had a great sound when rpms are either at low or high idle, a nice quiet YET deep sound, truly a lovely kit! Would recommend to anyone looking for a budget kit to have there squarbody breath!

    Can this kit be bought with short tube headers as my truck is a 77 c10 short bed that has been lowered. Long tube headers hang below frame rail.

    Asked by: terrybangel
    You can purchase this header to go with the rest of the kit, you may need to fabricate the connection from the header to the exhaust kit - https://www.jegs.com/i/Hedman/500/69010/10002/-1 https://www.jegs.com/i/Dynomax/289/89004/10002/-1 https://www.jegs.com/i/JEGS+Performance+Products/555/30210/10002/-1

    Does the kit include all the brackets, bolts and braces needed. And the mufflers are they on the quiet side or on the aggressive side as far as sound. 

    Asked by: 1973k10kid
    This kit comes with all the necessary bolts, gaskets, hangers, and clamps. The mufflers are on the aggressive side, comparable to an Original 40 Series Flowmaster two chamber muffler.
