The install is pretty easy.

Remove IC. (2 12mm bolts, remove BOV and unhook the brether hoses and remove hose clamps on TB and Turbo)

Remove heatsheilds. There are about 6-8 10mm bolts. Use air rathet if you can. Saves a lot of time.

Unbolt the DP. 14mm X 5. Start with the bottom nuts, as it has a tendancy to get stuck if you unbolt the top ones first, tilting the DP.

Unbolt the DP braket on the tranny and hanger. 14mm x2.

Unbolt the DP from the exhaust.

----------

Make sure to let the car cool off. You dont want to get the DP bolts get stuck. If that happens, a 1.5 hour job will turn into a nightmare.

its not completely necessary to remove the intercooler. i did it sunday without removing it. lots of heat shield bolts. otherwise quite easy. i busted *** and got it done in 40 minutes.

i really dont remember the size of it but you can just use a big open end wrench on it. remember to put anti sieze on any bolts your use.

downpipe gaskets do not need to be replaced. Uppipe gaskets are more then likely to leak if reused.
