i think he is asking how hard it is to install. iv never put one on but from what i read it is very simple and accessible,

It's a fairly straight forward install. If you don't want it, PM me your paypal and I'll buy it.

Yea it is pretty easy. I have done about 6 of them. The hardest part, if you want to call it that, is getting to and removing the back 3 bolts to the up pipes. I take the wheel off, remove fender liner, steering shaft and proceede to remove manifold from the head. I haven't had to replace the gaskets yet, just reuse the old ones. I like to use anti-seize upon reassembly to make it easier for future removal in case of any replacement or further upgrade. I have actually shaped and re-installed the heat shield to the new manifold for a factory appearance in the case of warranty related issues or concerns.:)

Here was a nice DIY, but the pictures seem to have disappeared.

Well on my first try it isnt all that bad but i had some problems. Once you remove the steering shaft and the air tube. its pretty easy to get to the 8 manifold bolts but then i got to the flange bolts and couldnt get them to budge at ALLL and i tried to lube them and the manifold was still pretty hot from running. soo yeah i had to throw it all back together stock :(

Fairly easy to install, just take your time and make sure you torque the bolts in the right order to correct specs or you will have exhaust leaks.
