I have to change back to my stock midpipe so I can pass cali smog. What tools do I need? I think it's a couple of socket extenders and elbows or something...
at the manifold left side you wont need any swivel, just extensions. Right side you will need the swivel, and 2 extensions to reach, i believe i used 15 mm socket with a 1/2 drive ratchet and 2 extensions. You will need deep well to get clearance over the bolt. Right side is a biaatch.
and to tighten down the o2's youll need the wrench (not sure size) or 02 socket with ratchet
The longer the extension the better for the most part. Nuts/Bolts are 1/2" or 15mm(I think), but I know for sure 1/2" will work, although I usually use a metric size. Swivels are good, and will work for most of them, but one nut on the right side is VERY difficult to get with a swivel...universal joints work better on that one if you can loosen them by hand, as you cant use an impact with a universal joint.
O2's are 7/8". I like to use a very long flat head screw driver for disconnecting the O2 harness connectoer.
the bolt that dragstr says is really hard to get at is the lower one. Its becuase if you go too deep well with it it rubs up against the exhaust pipe and wont go on the bolt. you gotta really get the right size socket not to short not too long. It is a PITA. You shouldn't need any pb blaster or anything depending on how long youve had the mid on.
