Quality, functionality, ease of installation all get high marks.I replaced the catalytic converter and pipes on my 1994 GMC Sierra 4x4 with the 5.7. Of course I had some of the original nuts that didn't come off and instead pulled the suds from the exhaust manifolds. Not an economical what to fix the situation, but timewise it was the right choice for me.I used a dab of copper grease on the manifold side and the double nut technique to seat the studs.Exact replica of the original in length and width. Same spring size and the nuts were, in my opinion, better than original.Hopefully you are wiser than I am and order a couple sets of these before you start the job as I had to wait for the parts to come in, in order to finish up. The old hardware just wasn't coming off without cutting through the old flanges. Have fun!

I would not recommend ordering these. I ordered 2 kits to replace all my studs on my exhaust manifold, and despite the description and the box stating that each kit had 3 stud kits (3 studs, 3 springs, 3 nuts), both times i ordered these and they were delivered, i only recieved two sets of 1 stud, 1 spring, 1 nut. There is nothing wrong with the studs i recieved, but only getting 1/3 of the parts i need twice in a row is very frustrating.

This kit was a good replacement for some of the damaged specialty parts on my S10 pickup exhaust.

Item was fine. Service from Amazon was discouraging. Apparently Amazon does not know how to count. Furthermore customer Service is not accessible by the customer. Amazon is a poor service company and not worthy of recognition.
