MOTORDYNE ART Pipes - Review

37drift

Thanks guys. Awesome to know that I'm not the only one. I trust Tony entirely, and definitely know that everything will be ok, but it's a little annoying when you pull up at a stop light and your car sounds like your exhaust is slowly working it's way off the car.

looks like i'll have to do some spirited driving this weekend. I'll let you know how it goes.

It sounds like grinding right! Lol it first sounded like metal being dragged now it kinda sounds like grinding. Im at the same mileage as you now (About 500, I got it on friday, yes I know I drive A LOT). So Ill keep you posted when it dies down. Quick tip the rattle does not appear if you downshift when coming to a stop lol.

started off sounding like a couple tiny pieces of ceramic bouncing around. the sound was very high pitched and the pieces sounded small. that eventually worked itself into sounding like a couple steel ball bearings bouncing around inside there. little bit deeper sound. pieces bounced longer after i let off the throttle. yesterday it sounded like a single marble. like, a large one. much louder, deeper clanking. today on the way to work was by far the worst. sounded like a flat metal plate bouncing around. sound is present under any driving condition.

i find myself shifting before the car hits 2,000 rpms to keep the volume of the clanking to a minimum. this is not fun. almost drove my vw to work today in order to avoid the clanking. i've really got to get this under control.

I just got done driving from FL to NY yesterday, yes I'm in NY at a hotel. Drove the Z straight thru. The ART pipes got slightly deeper as anticipated. Currently have 2200 miles on the ART pipes. Holding up good so far!

Don't shift that low. We all told you to punch it and heat the ART Pipes really well. Drive it hard for a day or two, it goes away.

I hear you. but man, I scorched the thing all the way home and back to work on the highway this morning. I don't understand how or why this is considered "Normal" break in. I'm a little uncomfortable with the fact that I'm screaming up and down the highway so that I can get a product to settle properly. The truth of the matter is that I don't *normally* drive like this off of the track. A pull at a stop light here or there, maybe, but this is excessive. Seems like there has to be some sort of agent or alternate product that can be used in order to get around this terrible sound.

Sound is absolutely unchanged, from cold start up all the way until I pull in my parking spot at work today. That includes a couple redline shifts, some goosing the throttle, and all around abuse that I wouldn't normally subject the engine to. No change at all. If it was a little sound, I'd be able to deal with it better, but this sounds like someone banging a serving spoon on an empty coffee can. Getting pretty frustrated with this.

Sound should go away bro. I am in the same boat as you and trust me itll be worth it. You and I both have G37's and around same mileage Ill keep you posted if there is change!

Let it break in to 1500 miles. If it doesn't dissipate we will replace them for you.

Also, make sure everything is tight. Did you make sure to cut the bolt? And what exhaust do you have? Did you make sure it isn't hitting the cross member?

The rattle for most of us didn't exist past 3500RPM. It mostly happened between 1500-3000RPM somewhere.

I know we cut the bolt on the first batch but I can't remember it exactly. Tony do you have a pdf of the instruction manual?

Man I know how you feel drift. I was so embarrased to drive the Z with all the rattling. I even made an appointment with a shop to have them inspect the pipes. Drive 30 minutes on the highway and upon arriving to the shop, I couldn't reproduce the rattling. Lol

I couldn't believe a rattling sound is part of the break in process either but I guess Motordyne knows their products.

I was on a creeper at 6:30 am this morning under my car, checking for anything loose or banging. Bolts are torqued, clearance is no issue. It's a perfect, text book installation. I started the car up and got under it. Sound is from inside the chamber. Can't tell if it's one or both, because the one closest to my ear drowns the other out.

My family owns a machine shop and we build race engines for a living. You have no idea how much of an earful I'm catching from my brother and our mechanics about this. I've been the laughing stock for 2 days now. "Ask him how much he paid for that rattle!"

Can I get a price for the tp to 98275?
