ZZP O2 and Midpipe Installation

[boats4life]

Guess I'll just kick this off, lol.

First thing I did after I jacked up all four corners was pop the hood and remove the heat shield. There are three bolts with some crazy @$$ heads on them, but they're not tight and can be removed easily with pliers if you don't have the right fitting tool.

Now it looks like this:

Then I went underneath and removed the underbody paneling. (I have an ECO) There are 8 bolts and a bunch of plastic pop fasteners (2 in each wheel well and one forward of each wheel well.):

This is the stock O2 Housing:

This is the stock midpipe:

Then I pulled the O2 sensor from the stock housing and opened up the V band clamp.

I didn't get a picture, but I removed the two bolts from the midpipe/resonator joint next.


Then, there are two brackets that the stock O2 Housing attaches to here:

It was hard to get to the aft O2 sensor, so instead of unscrewing it, I just unplugged it from the harness just above it. It was pretty tight with no lift, so I couldn't get a pic there either.

Stock compared to ZZP parts.

After that, follow the exact opposite procedure to put in your ZZP pieces.

Those silly bolts on heat shield can be removed with a standard 6 point socket FYI...

[boats4life]

Good to know- I left my heat shield off after installation... Not sure if I'll put it back on or not...

[limited360]

I put it on... you want to keep as much heat in the exhaust until post engine bay...

Skillz is gonna heat wrap all his ZZP pipes if I remember correctly.

Do you already have a tune on the car?

[boats4life]

Yup, sure do! That was my second mod.

Thanks for the writeup!

How much of the noise was the intake, and how much was the down/midpipes?

[boats4life]

The down and mid only increased the noise you hear from the turbo's wheel, not the BPV. Before, I could only hear pressure building from my intake, now you can actually hear when the wheel itself spools up. (that's that high pitched whistle)
