Absolutely. You can always add more to what is already there.

bump for the news about AWD fitting!

bump for that motordyne catback release

Hey guys,

Not sure if this is normal but I have about 1200 miles on my ART pipes and I noticed the vibration from it has gotten worse. Especially when I stop and have the car on drive, now I have to move it to neutral to ease the vibration. Anyone else experiencing this?

Also got my SES warning light came on, second time should I do another reset? Is it possible for the pipes to cause any damage to the car?

I have yet seen a good feedback after the latest design of ART, All of them are having issues.

Tony is there something you can do about this?

When did you purchase them?

Its normal for the breakin period to go up before it goes back down again but if it isn't gone by 1500 miles I'll send you a replacement. The new break in free design.

The CEL is not a problem but it does indicate the O2 sensor detecting free oxygen in the exhaust stream. If the sensor is still able to detect free oxygen it can be turned off if you get an Osirus tune.

Thoes are the prior design you are referring to.

The new ones with the vibration dampening bracket do not have a break in period.

Last week I wasn't able to work on it as planned but I'm back on it now.
The exhaust is all built and done. The only thing left to do is get it into a production stream.

Thanks for getting back to me Tony, I purchased the pipes back in early August. Didn't reach the 1500 miles break in yet, I'm around 1200 or so. Also I don't have the vibration dampening shield either, if it's cool with you I don't mind getting a replacement unit and not worry with breaking in the pipes.

Sounds good, I'll do a quick reset and try to find someone who has an Osirus tune.

Hey G37sHKS it's not true, many positive feedback with the ART pipes. There are some kinks to work out but overall I'm happy with the performance of the pipes. I'm sure many people who bought the ART pipes didn't regret it :icon17:

WHICH IS :ughdance:

I'll need to ask the fabricator for a production time estimate. (Its typically 4-5 weeks for production.) I hope to get at least a few production quality systems fabricated sooner ~2 weeks for pictures and ~1 week for sound clips.

waiting to see your exhaust before i order a F.I. Hope its good!

Right on. :)
This will be worth the wait.

don't want to be annoying, but still waiting info about the AWD transfer-case fitting! :tiphat:

The only time I have triggered CEL's, which has been about 4 weeks after install/reinstall, it has been due to an almost impossible to detect exhaust leak at the top flange. If you're not sure just reset it and wait, buy the time it comes back on it will be big enough to hear and detect if you get under there while it's running.

I would almost bet money if you get under there you'll find a leak.

On that note Tony, I'll be hitting you up for yet another set of gaskets. Once again it's burned through in the same spot, despite using the rtv in the manner you prescribed. When I pull it off this time i'm going to check the flange for flatness, to be sure it's milled correctly. Will you pm or email when they ship please, I'll let you know what we find.

Sorry, havn't heard anything yet.

AggieAv8r,

Try this, bolt it up without the graphite gasket and use only the RTV gasket maker. The RTV alone can seal it.

The ART pipe flanges are indeed flat. They are all ground and surfaced flat at the factory AFTER welding onto the pipes.

If there is a chronic leaking problem you might want to check your header outlet flange to make sure it is not warped or has anything unusual.


.

I'm going to try it without the gasket. What do you recommend as the cure time after installation before starting the car?

If you apply the RTV to the flange surface, let it air cure for a few minutes before installing it. Then let it sit overnight and its good to go.

GENERAL QUESTION ABOUT EXHAUST TIPS.

We normally stock 4.5" OD stainless steel and burnt titanium tips with either a straight or rolled lip.

Would more people be interested in a 5" OD burnt Ti tip with a rolled lip?...

Or is 5" too big?

Well the nismo exhaust is 5" right? I'd go for that, if there was a rolled stainless option.

Thanks Aggie, i'll give that a try and see if I get the CEL message again. Does anyone else have the vibration problem?

Burnt Ti straight tip.

5" all the way!

Go big or go home!

stainless rolled 5'' would be amazing.

Dont get me wrong, I know motordyne and I know Tony before he even join this forum :)

I love his products and he knows that. Its just many ppl complaining about the new art pipe, either CEL, rasp, noise, etc etc etc.. but now he fixed is usual by making the art pipe break in free :)

Hmm, I want to buy ART pipes so badly, but still don't want to be the first who will try them on AWD (G35x '07, VQ35HR) and find out it wouldn't fit, as I live like 10000 from the USA and it will be hard to return them...

Please, someone with the G35x/G37x - test fit them!

Tell you what. I'll send them to you with a 100% money back guarantee including shipping. If they don't fit, total refund... and you don't need to return them.

And please post pics! :)

Just wanted to post in here expressing gratitude for great customer service. The gaskets between my manifold and ART pipes blew out after installing my SC and Motordyne sent me new gaskets free of charge.

The high temp will seal the deal....

So that high temp sealant won't burn off? I've looked at some others, but I didn't think the temp for them was high enough.

Its made to take the place of gaskets. It'll take the heat.

They recommend the copper RTV for exhaust manifolds, can take the high heat a little better.

ehh only a difference of 650deg vs 700deg. I don't think it'll matter.

I have put high temp on all my cars through the years and it always solved gasket issues for me . Would never put on exhaust , art pipes or headers without it ..

^And this is why we now include a tube of high-temp silicone RTV in every kit.

That's a great offer!!! :iagree: :tiphat: I think my muffler shop can install them anyway even with the slight modifications!

It's hard for me to buy parts directly from the states. So, the local shop (streetpower.com.ua) that imports parts from the USA will contact you soon in a week or two to buy them for me (user harp00n, Vladimir Lvov) :driving:

So the RTV is used in stead of the gaskets? How does it take to cure b4 being able to start the car.

Does the RTV make removal more difficult when going back to stock.
