I've never had that code.

I just got the P2A00 and P2A03 today. I have Motordyne's gaskets, and I believe my shop also applied some of the sealant too. I have noticed an increased amount of vibration in my shift lever during lower RPMs, and the hiss (which used to be hardly noticeable) can be clearly heard on decel for a solid 1000RPMs. Not exactly sure what's going on.

I reset the codes with my UpRev, but I'll be taking it to my shop hopefully this week to look for a leak and pray that my O2 sensors haven't been damaged.

If you are getting a code, try this...

Inside the O2 sensor bung steel wool is packed inside. This steel wool is stuffed in to help reduce the occurrence of CEL's by reducing the sampled exhaust gas exchange rate to the sensor.

Try this. "IF" and only if you have a O2 sensor CEL, remove some or all of the steel wool in the O2 sensor tube. Some sensors may need to see a higher exhaust gas exchange rate to stay happy.

Its easy to do. Just take out the O2 sensor and pull out the steel wool with a hook shaped wire. Reset the ECU and drive like you always do.

Update on the exhaust.

Its on the 370Z now. The base structure is done and several configurations have been tested with resonators placed at different locations. So far I found the location that works best. There is no rasp, no drone, no hissing and no rattle snake sounds.

The right resonator location has been found, but what I would like to do now is experiment with a different size and type resonator at this location to listen for the effect on sound.

I could post sound clips of it now but I'm not completely happy with it just yet. I will be attending the SEMA convention in Las Vegas this week so I won't be able to do the experiments this week but I will start again next Monday.

Motordyne will remain open for business while I am out and I will stay in contact via email, PM's and this forum.

Hope you had fun at SEMA. Looking forward to seeing this new exhaust, sound clips, dyno #s, etc!

The SEMA convention is awesome. So much so that I wish all you guys could see it.

If you think hanging out in a Z forum is fun. Multiply it 10,000X for the SEMA convention.

SO MUCH NEW TECHNOLOGY AND VERY COOL CARS OF ALL MAKES AND MODELS.

Steel wool was removed and code is cleared just now. Wish me luck!

DarkZide · 11-14-2011, 09:31 AM

Been a week since SEMA. In for those exhaust updates!

Motordyne · 11-15-2011, 04:02 PM

A little hint on some of the design concept.

Helmholtz Tuning!

Paskii · 11-16-2011, 08:02 AM

Looking good Tony

Don't keep us waiting for too long

AlphaSnacks · 11-16-2011, 09:49 AM

I had a feeling the exhaust would make use of Helmholtz resonance. Torque should be pretty incredible with this then.

cheshirecat · 11-16-2011, 11:03 AM

Can't wait to hear this paired with art pipes.

It'll likely sound fairly quiet on start up, won't drone, won't rasp and won't fart. But it will most definitely have a very refined and nice tone as the revs wind. I'd imagine more akin to a louder 350Z exhaust, versus our sh*tty OEM 370Z exhaust.

It's basically exactly what I always look for in the sound of my exhaust - toned and not obnoxious. I hate nice cars that sound like ricers - we simply don't have motors that are refined and nice enough to be left to sing on their own like a lot of modern day V8s and especially supercar V10 and V12s are.

That's exactly what I want. I had a Bassani on my 350z and it was perfect. Retained the stock tone, but it was a little deeper and more aggressive.

Not really a fan of the high-pitched "Japanese" sound.
