MOTORDYNE ART Pipes - Review

Junior370z

Nice review! Curious to see the dyno number compare to others. Lastly, I know this will be a dumb question to some. What are the cylinders for welded to the pipes? Is that to help with exhaust pulse similar to what a X/Y pipe does? Thanks!

Now, Helmholtz resonance is a scientifically proven phenomenon. The property can be demonstrated with a glass bottle: As air is blown across the top of the bottle, some enters it, is momentarily compressed, and then surges outward at a slightly faster rate than it went in, creating a vacuum that draws more air back into the bottle to continue the process. Proof of this oscillation of air can be heard in the tone or frequency emitted by doing so. In the case of the products at hand, exhaust gasses are blown across built-in resonance chambers, and the frequency of pressure waves created therein pushes exhaust gas through the tubing and out into the atmosphere. Now, if Motordyne has one thing working toward their credit, it's that they're by no means an upstart company. Remember the plenum spacers that have become mainstays in 350Z tuning for their simple, low-buck design and solid power gains? Turns out Motordyne owner Tony Colette was a rocket scientist in his previous profession (no, seriously-he was), and he invented those. "Not only will the resonance chambers increase scavenging and power," Tony promises about his new products, "but the titanium tips on the Shockwave exhaust also reduce pressure drop by gradually expanding the exhaust gas to recover its dynamic pressure," which, he claims, also helps increase scavenging
