Motordyne True Dual X Exhaust
Ordering mine as soon as he lets me. 
The Motordyne True Dual X (TDX) is a 3" True Dual X pipe exhaust system with just enough dual 2.5" to optimize the highest level of NA torque and power!
No corners cut. No compromises.
When you need the best system with the most power, quality, real engineering, innovation and extensive R&D combined unparalleled craftsmanship... this is it.
Below are pictures of the Motordyne XYZ with Resonated 3" TDX midpipes.
This system is characterized by a deep aggressive rumble that can only be achieved by a dual 3" system.
The 3" TDX midpipe is fully compatible with any of the Motordyne Harakiri, Gamma or ShockWave))) axleback sections.
The system shown below if for the G35C. The 350Z system is the same but the tubes are 8 inches shorter behind the resonator outlets.
Quality welding and craftsmanship worthy of aerospace applications.
The transition between 2.5" and 3" strikes the optimum balance between high velocity for scavenging and reduced velocity for reduced pressure drop.
The dual 2.5" tubing keeps velocity highest near the engine where it is needed for scavenging. The diffusion to dual 3" tubing reduces velocity where scavenging has become too weak to be effective and the high velocity (and resulting pressure drop) becomes a hindrance.
Note in the picture below how the resonator outlets are dual 2.5". They have a gradual expansion to dual 3" diameter for efficiently converting dynamic pressure to static pressure. Proper diffusion of the high velocity gasses reduces the overall system pressure drop.
This system is very capable for use with NA and even high HP turbo applications.
And if for any reason, the dual 2.5" primaries still aren't enough for your high boost turbos, the 2.5" section is very easily switched out for a completely true dual 3" section.... Making for a 100% dual 3" exhaust system.:biggthumpup:
The full catback ShockWave))) TDX is $1695
This is a no compromise exhaust system.

,isn`t that the same exhaust that you are running now ? at least from the XYZ & the Down Pipeyou want to test it again
if not the same ,where did you get yours i couldn`t fine any in Moto site .
sounds beautiful by the way but you didn`t try to run iy WOT in the video ,why is that ? just to see how it sound then and if its raspy or not .
thank you ,all the best
anan
For me, I like the sound of the resonated version though.
What's the pricing gonna be like for a Harakiri TDX (I assume this is a full catback) for an 08 350Z? I assume with the TDX you will not have the option of the XYZ Catalytic Converter.

Once everything is posted on the website, it will be a veritable exhaust boutique where you can build your exhaust system just about any way you want it.
And yes, that is correct. The the XYZ catalytic converter won't fit the TDX.
I can vouge for the quality of the dual shockwave. Once I heard TheOtherRob (Rob's) in person, I had to get ride of my borla. There is no exhaust out there that sounds like it. I am the first to have the dual shockwave exhaust with resonated testpipes to make a video. The video of the before and after will be up within a day. So keep your eyes open for the videos. Tony gives you top notch product with top of the line customer service.
lol sorry Rob. Just couldnt let it pass me up.. plus its going to be good for the ST im getting in 1-2 months... yayyyy. FYI there is a suprise in the family of the z's that we know. 
Oh When I see you for the next meet. I want to compare mine and yours. Since I have resonated testpipes and you have stock cats. Yea it is deffinately loud and there is no rasp at all.

and Yes that exhaust note is just amazing and the quality of the welds and materials overall is top notch.
