Gratz!!

No true dual Exhaust (2.5") for twin turbo families??

Motordyne

Its a hybrid of dual 2.5 and dual 3.0". And trust me, its far better for the turbo dyno curve.

I've seen what all dual 2.5" does and what all dual 3.0" does and neither provides the best overall performance in the 400HP-650HP range. They each have their compromises.

Having the 2.5" primaries on the XYZ tremendously helps the midrange and TQ for FI applications. I won't recommend 3" primaries unless you go to really high power. 700+HP.
Having the dual 3" past the collector provides the best HP.

It would have been cheaper and easier to manufacture the system all out of the same diameter tubing from front to back but that doesn't provide the best results on the dyno.


Having a progressively larger and larger diameter on the exhaust provides the best power results. FI or NA.

2.25" on the ART pipes.
Expanded to dual 2.5" on the XYZ primaries.
Expanded to dual 3.0" after the merge collector.


Small diameter pipes close to the engine increases scavenging but as the exhaust gas flows further and further away from the engine, scavenging has diminishing returns. Eventually it gets to the point where small diameter starts to create more pressure drop than scavenging and that kills HP.

It can't be too large and it cant be too small and it all depends on location.

That is why this exhaust has continually increasing flow area from front to back.
It dynos better this way.... and it sounds better too.

cant wait to hear it!

In for video/sound clip!

+1, might be time for a new exhaust.

Looks like you're just about ready to make a new thread dedicated to the new exhaust!!

Yeehaw!

^^ I agree.

My M370 and ART pipes are treating me well...I'm tempted to jump on a full motordyne train if the price is right

For some reason I can't get the video to imbed but here is the link.

Motordyne Shockwave exhaust system for the Nissan 370Z. - YouTube

Motordyne Shockwave))) Exhaust with ART test pipes for the Nissan 370Z.
Dynamic range test. Low throttle position 1 minute. Wide Open Throttle 30 seconds.

This is a close stereo mic recording of the exhaust system where high resolution, directional microphones are centered and aimed directly at the tips from 18" away.

You will notice the microphone is sensitive enough to pick up the subtle details such as gravel noise, road texture or even the license plate frame occasionally rattling.

The 370Z starts driving down the road quietly but as soon as it is down shifted and slammed WOT it opens up loudly. No rasp and no drone.

Drive by sound clips will sound substantially different and will be made as soon as the rain stops.

Thank you for the imbed tip!

The clip here is a continuation of the clip above with a lead foot much of the whole way through.
