MOTORDYNE ART Pipes - Review

370Z JT

Tony,

At least 4 members including myself have reported SES lights (P2A00 and P2A03) with the ART pipes V2. Do you think it has to do something with the revised design?

I did not encounter any SES issues with V1.

Regarding the SES lights ... check for exhaust leaks.

Osiris

did you get a SES? If so, was it the same codes mentioned above? Is the exhaust leak what caused yours?

Had this exact same problem with gasket.. iT GOT incinerated. I changed it but still got SES though

I have the exact same issue with these gaskets - with 2 different sets. The Berk gaskets and the Motordyne gaskets. When I received my replacement set of V2 pipes the gasket was destroyed. Unfortunately new gaskets were not shipped with the new set - huge inconvenience. Now I'm waiting on some OEM gaskets and will once again change these out.

All these are blowing out on the same side - inboard and just below that bolt thats extremely tight from the factory. We have been sure to tighten that as much as "physically" possible and are still developing leaks. Not sure what's to blame, the machined face? Gasket material?

You might still have a leak if you are throwing the SES

First, I want to say that the customer support from Motordyne is fantastic. I had a leak from blown gaskets and they sent me replacements at no charge. I had them installed over the weekend. The difference was amazing but unfortunately short lived. I posted the picture of the blown gasket several posts back.

• The fuel smell was gone
• The SES was gone
• The nasty, raspy, whooshing noise was gone
• The exhaust note was almost stock, very quiet
• Now all of that is back, keep reading ….

Granted, I am on the OEM NISMO exhaust, but I could hear a rattling, whoosh noise directly related to the amount of throttle applied. It was easy to identify once I knew what it sounded like. Having the car leak free enabled me to identify the leak sound. If I accelerate up to say 30-40 and shift to 5th/6th and floor it, I could easily hear the raspy leak. I thought that was just a test pipe noise but realized that was the exhaust leak.

Replacing the gaskets significantly quieted the exhaust. However, the new gaskets lasted about 72 hours. I have searched around and cannot find a metal based replacement. When I had a Random Technology HFC on another vehicle it came with metal based gaskets. I do not think these fiber based gaskets are working, but I cannot find a more suitable replacement. The same tuner (Jotech Motorsports) did the initial install and gasket replacement, so I do not think it is an installer issue. I am SC’ed but that should not increase exhaust temperature or otherwise compromise the gasket.

So, I am seriously considering going back to the OEM cats. Again, this is absolutely no slam on Motordyne. They produce a great product, but I think some applications need a more durable gasket. I cannot explain why the vast majority of Motordyne ART installs have no problem. The problem seems to be limited to a few buyers. I have no idea what the underlying problem is with the people experiencing the leak problem and then the SEL.

Just my experience and I want to keep the pipes but I need a gasket solution.

Motordyne

No, not at all. If anything, its most likely air leaks that are the cause.

Osiris

if air can get in, than can't exhaust get out?

Both. Leaks let air in and exhaust out.

Each code refer to each side. Leaks on both sides?

I had a shop check the install already and said it was fine. Dead O2 sensors?

If they are sure there is no leak it may simply be the sensors are able to detect the difference with the ART pipe stand offs.

The sensors would only be dead if they were improperly handled. (or mishandled)

if one has an exhaust leak... woiuld you hear it more when giving it gas or letting off? I have a sound on mine, but it sounds like what others have described with their ART pipes... I explained it to Tony that it sounds like sand hitting the inside of the tubes of the ART pipes. I am going to go over all of the bolts tomorrow and make sure everything is all tight.

As far as the SES lights go though... I have now over 500 miles on my MD pipes and no SES light.

Im interested in this ART pipes, how do i get one?
