I ordered these and they arrived well packaged and quickly. I had a shop put these on for me along with some Magna-flow catalytic converters and a Flowmaster cat-back system, so I cant really comment on how hard they are to put in. I do want to say that they did not come with new exhaust gaskets for either end of the headers. I noticed a definite increase in horsepower and engine response, but I replaced the whole exhaust from the block back. Overall I give em 4 stars (a bit expensive)

Great Headers / The wait was over 2 months.

The quality of the headers is excellent. I do not know how hard the installation was, as I had a local exhaust shop do the install.The disappointing part was that I has to wait over two months for the headers.
