Easy to put on if you have all the right tools. Haven't had it on long enough to notice mpg increase and the fact that it sounds better I can't keep my foot out of the gas.

I had a bad gasket leak on my drivers side exhaust manifold and was looking at about $400 to get it fixed and have the same old performance out of my 4.7L Magnum engine. This was a PERFECT time to upgrade and get these Gibson Ceramic Headers instead. Since installing them I have noticed a big difference off the line and also in acceleration! I had my truck on the dyno and gained just under 10HP... I'll be adding an open air intake system, an ECU controller and performance exhaust this Spring.

The reason I bought these and the only reason I bought these is because they are California exempt the sticker supplied with the supplied with the header is just a plain white piece of paper it's not going to withstand the test of time it's gonna rub off I'm not gonna be able to get smog all other manufacturers use something like a metal sticker so I call FlowMaster advise them of my concern asked for a replacement for her like a stick inside the glove compartment of my car and they refused to give it to me so far one guy wanted for her to tell me just going to write it down on a piece of paper I double checked
