Shipping updates?

I tried ordering Friday and he told me to wait until he knows for sure that they're in stock. Estimating that they would become in stock July 6th or 7th.

Soooo... Would it be generally agreed that if I was to make one, and only one mod to my 370Z, and I had no more than $500 to play with, I should buy these art pipes? Also, does anyone have any comment on the effect of these on MPGs? Slight increase, decrease, the same?

if your looking for more power and a deeper exhaust tone then yes.

If your looking for Pink Hello Kitty stickers then no :p

Hot out of the kiln. :)

TITANIUM CERAMIC

They should all be out of the kiln later today.

Beautiful :)

Shipping by tomorrow?

Yes. Feel free to contact us if you would like a tracking number.

Thank you!
Tony

Got mine today! Only issue was with the threads in the passenger O2 bung. The OE O2 sensor would not screw in correctly. The tech said its due to the ceramic coating getting into the hole.

Anyone got a CEL with these?

I did, after about 2 weeks. Haven't checked into it yet though (guess it's still possible that it could be something else, but we'll see).

Thanks for the heads up. I'll ask the ceramic coater to be more careful on the overspray.

No CEL's with mine after a few weeks.

The ART pipes sensor bung, by design, will be very resistant to throwing a CEL.

If you ever do get a CEL, the first thing to check for is an exhaust leak. Exhaust leaks will throw a CEL quickly and easily, but that is also very easy to fix.

If there are no exhaust leaks, CEL's with ART pipes will be extremely rare.

Hi Guys,

Just an update - Please allow the ART pipes to have a break in period. ~1500 miles.

The fiberglass packing material is coated with a varnish like substance. A silicagel spray. It helps to keep the fiberglass from floating around during the packing process. Its the same type of fiberglass and coating that is used in mufflers where it goes through a break in period. This coating goes through 3 phases. 1) fresh from the factory where it is semi-rigid. 2) When it is initially exposed to the water vapor in the exhaust gas the silicagel solidifies the fiberglass to a rigid mass and this lasts for about 1000-1500 miles before it begins to soften back up again. 3) After about 1500 miles the fiberglass begins to soften up again and go back to a soft fluffy fiberglass state again. And this is where it reaches its optimum damping charecteristics.

Through the 3 phase changes you will hear a moderate change in the sound. This is normal. After break in the sound will remain constant and attain a smooth deep burbly rumble.

This may also be the cause of the hissing sound I get while on the gas. I will report back.

What exhaust do you have?

nismo (oem)

Its likely just the interaction with the stock exhaust. As with all exhaust parts there is a strong interaction of parts. One part that may hiss when connected to ART pipes wont hiss when a different exhaust is connected.

Different interactions of exhaust parts is normal.

Got mine today. Apparently "Fragile" Means that the Fedex guy should use it as a chair for lunch...I would have said something but I had to have them leave it at my house since I wouldn't be home when it was delivered.

The gaskets were a bit mangled, but i flattened them out and they aren't ripped or anything.

The pipes look great. I just hope they aren't bent a little by whatever squashed the box.

Now I need to find some time to get these installed!

They look amazing. I just off the phone with Tony. I put in my order :tup:

man they had to drop that box of something pretty high or drop something on it for it to look like that. thats terible. glad everything was ok inside though.

Motordyne has always made quality products!

That's terrible.:icon14:

Where would you like me to send replacement gaskets?

Pm'd. Class act Tony. :tup:

Haha yep my box looked just like that. I swear that "fragile" means "use for a kickball" to fedex..

Unfortunately, I am experiencing the same sound Arnold K was having even wiith the new pipes. Started to occur after 200 miles. Sounds like a ball bouncing around in a tin can. It goes away after about 30 seconds on a cold start but can still be heard while driving. Also, a SES light popped up around that time with a P2A03. Will have to take it back to Amp to have them look at it.

370Z JT: Drive the car hard for a few mins. Tell me if the sound goes away. Redline 1st and 2nd. Usually, when I begin to hear the rattle, I'll just goose the throttle in 1st and 2nd a few times, and it stops. If I have a good enough stretch, I'll give 3rd a press too just to heat things up. After that, it doesn't come back for quite a while (over a week usually).

According to Tony this is part of the break-in process. I'm approaching 1000 miles on my 2nd set, so hopefully mine stops for good.

Its mentioned in the prior page here.
The fiberglass gos through a hardening and softening transition during break in. Give it some time and the fiberglass will soften and then it will dissipate.

:driving: Can't wait for mine.

I see Ebay Y pipes mentioned.. I haven't looked, but is there a cheap H pipe or whatever it's called? I'm not used to this dual exhaust stuff... I came for I4s lol.

Will the pipes fit the new motor mounts for the GTM stage 2 SC?

If the motor is physically moved in location and sams headers end up in the oem location it will. If the motor itself doesnt move, just the way it mounts it will work

Now if sam makes it so the oem tp location is moved, aka have to use his headers and Tp/hfc then it wont work. I dont think hed do that though

The moter is not moved the stage 2 touchs the mounts.

The ART pipes have the same envelope as the stock cats.
If stock cats are compatible with the stage 2, the ART pipes will also be compatible.

Hey Tony, I'm not sure if you've heard the GTHaus exhaust for the 370Z before but how do you think the ART pipes will affect the sound/power compared to ERZ HFCs? (What I currently have.) I'm thinking about buying these and selling my ERZs before I install them if it'll be less raspy.

The general effect of the ART pipes is to make the sound deeper with less drone and rasp than regular test pipes.
Relative to HFC's, HFC's generally sound dry'er and ricey. And power will be higher with ART pipes.

Received my new gaskets today. Thanks Tony!

Any updates Tony? (Fingers crossed that they ship this week)

The sound of my ART pipes has definitely started to change. The hiss has changed to more of what I consider a "traditional" rasp, but it's much quieter than before. It also sounds like all of the sound is coming from the exhaust tips, whereas before the hissing sound was coming directly from the pipes themselves.

I'm interested to see how they'll sound when I hit stage 3 of the break-in process.
