The good part may be with the "super top secret" exhaust mod that this thread was started for. I did more testing on an improved version recently and dynod even better results.
The dyno results are so good, it's unbelievable... literally. I would get flamed and F-U'ed for posting the numbers.
So, I'll skip that part.
When the time comes, independant testers will post their results and take the punishment.
I will be doing more testing on it today and tomorrow. And this will be for the biggest, most important test aspect of all... a test for what I believe may reveal significantly increased fuel efficency.
Wish me luck for positive results on this one.

So, the secret exhaust mod is still a way off from being released and sold to the public, while ur exhausts are almost ready for sale?

Tony, if you want a FI tester, let me know. I am looking for something quiet that flows. I have custom 3.5" in/out hfcs hooked up to an evoTT and it's still too loud for my tastes. I was going to add an X pipe and a 1/4 wavelength resonator to eliminate drone at 2000 rpms (approximately 26" of piping T'd off each bank), but if you think you're system might be able to work for me, I'll hold off.
Lemme know.

PS. Whatever happened with the Evans stuff and the Motec hook up?

OMG WTF IS THAT EXHAUST!
It looks like he welded on some trombone horns and then flattened them a bit going over a speed bump.
That is HELLA RICE! It hurts my brain to look at them, what an embarrasement.

I eventually went with a FCON.
I still need to run the Evans test though.

The exhaust is starting with the XYZ pipe and various 350Z components and branching out to the other cars.
The XYZ pipe is univerally compatible with all G35C's, G35S's, 350Z's and G37's. This is what will be at the heart of the MD exhaust systems. (It will also be compatible with your Amuse.)
There are so many configurations for each car, it will take a little while to get everything out.
Thanks!
If this is as good as it sounds and sounds as good as it sounds, I'm deff in.
Now, I know what an X-pipe is and what a Y-pipe is and a Z-tube, but whats a Z-pipe? or do I have to wait for official release?

Its actually pretty easy. Its a multi function merge collector that can be used as a X or Y. The Z portion is a module that can be changed out for different applications and power curves when used as a Y pipe.
Fabrication says they will be ready next Friday!

More great news on the dyno today! Increased fuel efficency and even larger HP and TQ deltas than before!
There is a clear correlation between Volumetric Efficency and Fuel Efficency.
