Arrow Easiest Up-pipe

What is the easist up-pipe to install on a WRX? Or are all up-pipes installed exactly the same way?

While the detailed steps and photos on www.scoobymods.com look complete, they also make a up-pipe install look like a major pain.....

an uppipe install is a pain in the butt. I highly recommend you do it with somebody who has done a couple of them. I've done 4 now and each time I get better at it.

I'd recommend installing a nice, shiny manifold at the same time, it's alot easier that way

You should consider doing your downpipe (or full turbo-back exhaust if you can swing it) at the same time since you have to remove the stock one anyways for an up-pipe install. An aftermarket downpipe should be easier to reinstall.

And to answer your question, most up-pipes are the same level of difiiculty. I don't have any experience with a flexible up-pipe, but they may be slightly easier to fit in place, but you still have to disassemble all of your exhaust piping to get to it.

I agree with "fueledbymetal"s comments.
You should really install UPPIPE along with DOWNpipe or TURBOBACK exhaust.

Like he said, you will need to disassemble all the exhaust parts including manifold anyway. The uppipe will come out through the top without having to jack up the engine...(There isn't really a good place to jack up the engine anyway --DO NOT JACK UP THE ENGINE USING THE OIL PAN!!!) ..

In order to do that you will need to remove couple of brackets that are holding the 2 hoses (passenger side parellel to the engine:AC and other) to create the room. Just loosen the bolts holding the hoses in the engine block but remove the one that are holding the bracket underneath the downpipe.

Also, the detail instruction about removing the manifold that Perrin instruction is missing.

The heat shield will prevent passenger side manifold to be dropped even after unbolting the crosspipe and uppipe.
So, remove the heat shield surrounding the driver side mainfold and unbolt them to remove the DRIVER SIDE manifold... Now every exhaust pluming should be off the car....

After that you must follow Perrin's instruction to re-assemble..

--Bolt the DRIVERSIDE manifold but do not torque yet.
--Bolt the CROSSPIPE but do not torque yet.
--Bolt the Uppipe but do not torque yet.
--Bolt the PASSENGER SIDE manifold but do not torque yet.

--Torque CROSSPIPE to passenger side manifold.
--Torque Uppipe to passenger side manifold.
--Torque DRIVERSIDE manifold to engine block.
--Torque PASSENGERSIDE manifold to engine block.
--Torque Uppipe to the turbo.
--Assemble DOWNPIPE and other exhaust..
--Assemble heat shields....

I hope this helps.

Dan from PA.
