MOTORDYNE ART Pipes - Review

By the way, the ART pipes would be one of the best investments you could do to your car IMO.

The flanges are checked for flatness and put through a planer if it is needed. The planer grinds the flange flat after welding.

Have any of you guys with gasket issues tried like the permatex high heat gasket maker? It might be worth a shot you never know right?

Gasket should be about 0.050", no?

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

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.

My gaskets seem to be fine at this time but out of curiosity, what gaskets are you guys having issues with? Top or bottom or both?

Kostick, My rattling literally hung around until the 1500 mile point. I really did not think it was going to go away. I drove the car as much as I possibly could on the highway. This past weekend I started up the car and I was like, woah, I don't hear it anymore. drove with my head out the window (ace ventura style) and was smiling all the way home.

Top part close to exhaust manifold.

Thank you wind.zero.

And yes, a leak will reduce gas mileage because when air gets into the exhaust, it fools the sensors into seeing a lean condition, the ECU tries to compensate by richening up the mixture and thus gas mileage goes down.

Tony... if one were to make a template and cut it out of aluminum... would that work? If so, what size would be best to do so? I figure aluminum would be best in case it needs to bend a little here and there to conform to whatever pipes it's mating up with.
