2008 Yaris Sedan 5MT W/ Catback Magnaflow
 

I hope I posted in the right section.

I would like to begin a somewhat accurate analysis of the catback I have and two more to come (total of 3 variants for this sedan).

Background:

Magnaflow Inc. decided to do prototype catbacks for the Yaris Sedan and the Yaris Hatchback, Both 1.5 L, Sedan= 5MT Hatchback=4AT. My car is the sedan with 5MT.

Currently with Variant 1

Variants:
1. Dual Center
2. Single Rear (Pass Side)
3. Tip in muffler Single Rear (Pass Side)

Hatchback:
4. Dual Split Single

Why did Magnaflow decide to start support for the Yaris?... It is selling very well. Support is starting to build for it, espcially the hatchback variant.

They chose to do 3 variants for the Sedan and have a 4th variant specially for the hatchback.

What I would like to do is have 3 tanks for each variant.
1. Where I'm really watching the mileage, Hypermiling every single opportunity.
2. Driving as if a "normal" person would.
3. "Spirited" but legal driving.

I need help setting the parameters for each driving style so that I can do it for each variant. I also need someone to give me the rundown on how I actually calculate the mileage so I'm accurate.

What am I looking to get out of it?
I want to be able to give Magnaflow feed back from a broad range of views/ driving styles. Show performance advantages/disadvantages, same with MPGs.

Is there anything I'm missing?
Will start new tank, Shell 87 this comming Wednesday. 03-06-2008


Everyone's input is much appreciated,
