Okk, I finished today!!!12-17-09
I am going by my muffler shop tomorrow to take pictures.
I was on the hwy that I made a test run on last month so I hit the re-set button and got in the slow lane.
Only did one run but I got 28.9mpg.
Which is about 2 mpg lower that last month with just the front pan.
It was colder (by 15 degrees) and wetter. not raining but overcast anf damp.
But, it's CA and the weather will get better!!!
I am guessing that the fuel formula is also different than a month ago?

finished....pics

Here is the view form a lift at the muffler shop.
BTW the shop owner was VERY open-minded about the whole process. He must have had 5 different people looking under the car!!!

From the rear- driver side:


from the rear passenger side:



Down the center:
the squarish cutouts are where the exhaust pipes dipped too low....so I used screen material. This way the heat disapates out but the screen acts as a smooth surface for air flow.



I need to get a panel here still:

Front panel from the front:

Looking great!

Something that you might want to consider...visibly mark the jack points so a jack doesn't go through the floor pan by mistake.

BamZipPow,
EXCELLENT POINT!
I am actually going to install blocks of hard wood, that have been wrapped with black gorilla tape and have a metal strip just under the tape. I'm planning on 1x4 x6". then pre-drill holes in the metal/wood and a smaller hole in the mounting point.

Added this to the project library.

About your early on-road MPG results: A-B-A testing of undertrays isn't really practical. I managed to do A-B testing of my full undertray, and measured a ~2% change (see http://ecomodder.com/forum/showthrea...9.html#post873 ). Apples/oranges, though - every vehicle is different underneath.

As long as you're not increasing frontal area (doesn't look like it), you can be sure this helps.

I don't think you should cover the exhaust pipes at any point along their length, regardless of how high or low they are

....because it traps the heat?

Yeah. Cars with underbody panels leave the exhaust pipes uncovered, I assume because they need the airflow
