the SC brings more heat...and so far nobody knows what is causing the current gasket problem...but heat is a possibility. I don't want to go through hassle of installing pipes only to later have to take more time and money and hassle just to swap out gaskets. Would rather wait til the issue is corrected.

Don't give up.. All u need to do is put enough high temp sealant on the gasket and no blow puts.. It has worked for me everytime ...

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.

Understandable fix, but we should not need to this.

Gasket should be about 0.050", no?

Tony is a top notch guy and if there is a problem you can be sure that he will address it. Just keep your pants on lol.

These are the same gasket materials we have used with good success for several years but I'll look into more options.

You don't want to buy the part because of a gasket issue? Berk is having problems and maybe others as well, the problem will get solved I personally have not had issues in 500 miles... we'll see if that keeps up.

If you look at my posts bro I have been nothing but patient and encouraging other members to buy this. Small drawback for such a great product (even though I still got rattles 37drift gave me hope though!).

Just can't fathom having to pay again to get my gaskets switched again in the future.

why don't you do it yourself? It's only removing a few bolts and putting the gaskets in place.

Tools and time. Been swamped at work (13 hour shifts) so last thing I want to do is swap out a gasket lol..

I blew my gaskets out this yesterday on the track, installed last weekend.

How do you guys know that the gaskets are blowing out? CEL? Louder sound? Car acting funny?

Just curious.

Nasty noise, you'll know when your gasket is blown lol, sounds like $hit.

Btw can you tell me when your rattling stopped.

This is my list on how I could tell the gaskets were blown:

Strange, raspy, rattling, whoosh exhaust notes directly under the driver/passenger. I have the OEM exhaust so it is really evident inside the car.
More pronounced smell of fuel/exhaust than normally with test pipes
SES - P2A03 and P0171
Poor fuel mileage, I checked on the 2 days I had a good seal and was getting at least 3 MPG better. I think this is what caused the P0171 to make the O2 sensor think I was running lean.
If you can get under the car, you can visually see the area of the leak (a very dark, black area) between the flanges. I could see a spot that appeared to be missing gasket material but it was actually burned all the way through.

My installer suggested this:
Add an exhaust gasket sealant in additional to new gaskets. Hopefully, this will do. If not, we can buy a sheet of metal exhaust gasket and get it cut out via WATERJET.

I am probably going to go the metal exhaust gasket fabrication route because I am guessing it will be the most durable in the long run.

I completely agree. Tony and Motordyne are extremely good vendors with excellent customer service. I would not let the small percentage of people with gasket problems deter anyone from buying the product.

This will get sorted out.
