Just a few updates; we decided to go APR stage 1, nothing crazy but worth the bump in performance. At the same time we installed the Remus racing cat-back system.
The exhaust is very mellow but produces a nice extra bit of sound. At low rpms the sound is throaty and burbles lightly, at higher loads and RPMs the main sound is rushing air like a jet engine.
We did dyno testing at Makspeed in Temecula to try the different APR maps, including 100 octane using VP HP101 fuel, everything was pretty much as advertised, and the 100 octane tune was impressive.
On 100 octane we made 276.4 hp and 306.6 lb-ft to the wheels.
Here is a link to the full article and video of the exhaust.

There were a ton of little loose ends to wrap up to really make this project what it was intended to be. I didn't mention them as I went becuase I was focusing on the big picture parts and projects. Now the car is almost done I wanted to show a few of the details that took a lot of time.
Here is a link to the full article going through all the details:
http://www.turnology.com/tech-stori...fabrication-projects-tying-up-the-loose-ends/
I was really tired of hoisting up a wheel and using lug bolts, so studs from ECS were one of the first little changes.
This car sees a ton of dirt and rocks, so a skid plate was a must. I have heard how fragile the stock cast oil pan can be so I decided some aluminum plate would be cheap insurance.
With all that gravel and dirt, I wanted to provide the body a little bit of protection, and in keeping with the rally theme of the car a set of mud flaps were required.
When I Installed the ProFlex gravel coilovers, the mounting location of the swaybar endlink moved. As a bandaid fix I cut down the stock end link and welded it back together. Knowing what loads this car would see on rough terrain I figured it's only a matter of time before I break one of the links.
I decided to get some rod-ends and tubing and fabricate some much beefier endlinks to fit my custom application.
The last vital bit was securing the external reservoirs for the front struts. I don't want these pressurized aluminum canisters bouncing around under the hood, so I fabricated some brackets.
Using aluminum tubing and plate I made cans that clamped the reservoirs in place. I re-used the mounting holes and hardware for the top tabs of the headlights.
