What all comes with this system? Does it include the I pipe, or only up to the over-the-axle pipe?

I am wondering if I need to buy a larger I pipe or if the Mufflex system comes with everything needed to bolt up to the Mufflex y-pipe.

Any pics!?

 

They come with everything. I-pipe, over the axle pipe, muffler and tailpipe, as well as hangers. Kickass setup. I had the 4".

 

I'm thinking of doing the 3.5" just for clearance.

Anyone have any pics of the hide away setup???
