with that said it seems like the rasp is a little more than those that have hfc and less than straight test pipes.. which makes perfect sense...

My setup has zero rasp.

i love the sound man. I replayed it like three times already

Nice!

Invidia is a nice choice, Classic tone..

that sounds great man, i didnt hear ANNY rasp...mine should be here next week!!!

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

^ It works, the more I drive it the better it is, these are the best bolt on I have run to date. You will love them.

Putting on an M370 in New Year...

Videos planned for 26th December

NB - I am very careful with my purchases and try to get the best for my $$, I do my research, its nice when your choices are proven correct. ;-)

Thanks for the explanation!

I learn something new everyday!

cant wait to see/hear drive-by vids and see the dyno numbers...

^ I'm pretty sure he copy and pasted the import tuner article.

Nice. Im looking forward to this setup!

GZ3 · 12-23-2010, 11:12 PM

i shooo did...as long as it helps

Kastley85891 · 12-23-2010, 11:17 PM

^ ha ha - at least its the right info
I am tryng to get Wifey to allow a purchase of my CBE to complement these, as in with my theme, its gonna be the topspeed single pipe/ dual muffler for now.

Videos as she sits today will be up tom evening, nice.

GZ3 · 12-23-2010, 11:25 PM

got the freakin plager police over here!

Kastley, have you heard the CNT exhaust?! its supposed to be out pretty soon and its project to be around $600..not bad

Kastley85891 · 12-23-2010, 11:43 PM

Yep - it looks decent for the cash for sure, I wanted Y pipe and single pipe for experiment so will prolly go that route for now.
