While it wasn't the easiest to install, it was sure worth it. I do recommend buying new studs as well as crush gaskets for the piping after the header. Sounds great, gave the performance and flow I was looking for, and look badass!

Well first off, the manifolds look nothing like the picture. You can see all the heat/burn marks from the welds and overall look was horrible. There is no real difference in sound (as expected installing aftermarket headers), but I can tell a little difference in power - Maybe 8-10 horsepower. If you're looking for performance and sound, this is not the product for you. If you simply just want to replace the stock cracked manifolds cheaper than from factory, then this is the product for you.
