Warning do not buy Motordyne products
 

I have the MotorDyne test pipes v1. 3 separate times this piece of sh1t test pipe has cracked in 3 different locations, and needed repair welding.
The welder at the shop has said that the metal is cheap and thin.
Last night driving home, the extended o2 bong completely fell off and dragged on the highway all the way home. Luckily I was only an exit away.
Looking at the o2 bong, I thought it was just hardened carbon buildup. Nope, it's metal. I had a hole drilled through it to confirm, which also makes sense why I've always had a check engine code running these test pipes since there was absolutely no air going to the o2 bong in the first place.
Motordyne is absolute garbage. Never getting anything from them ever again.

Wow that's pretty bad good find and right in time was about to purchase those r-specs

Ok, got it!

This is horrible workmanship if this term can even be used.

**** happens. Metal gets hot, it weakens. You want stuff that doesn't break, put you're money where your mouth is. You're gonna pay double though for 321SS vs 304SS. Also you said version 1. How old are these? A new company probably isn't going to shell out tons of money for the highest quality 304SS. Over time their new versions might have it or they went thicker. Ragging on a company for a first gen product isn't really fair. FI mufflers first gen drug along the ground so I say screw all FI products, never buy that crap too, right? Was Kia the best of the best their first time out? They may not have a warranty but that doesn't mean Tony can't be called and asked "what should I do?"

A weld broke on the Fast intentions exhaust I have, the left rear hanger weld,,,also a weld is broke on my right Motordyne art pipe on the support they have between the pipes. They must be crap companies. This car also obviously sees road salt, it will eat the crap out of the metal, look at those pipes...

It may be v1 but it's unheard for a relatively expensive product to crack 3 separate times. No warranties. The fabricator must have been a newby or smoking some good stuff the day they made mine. This is the type of quality I'd expect from eBay products

Joe, thank you. I feel like an idiot. I forgot the name of the company. It's not ARK, it's Motordyne. My apologies to ARK. Motordyne is the problem.

Glad we got that sorted out :tup:

Good job getting the title changed, but please edit the original post to correct the additional company name references :tiphat:

I changed it on the title and everywhere else i mentioned ARK but it doesn't change on the title in the listing

We can PM the mods :tup:

Lol pssssst, (whispering) everything's made in china. :tup:

Retitled.

And sorry to hear about the crappy weld. :(

304 wouldn't do that unless it was hella thin, this probably 406 or another 400 series, i have a set of gtm test pipes purchased back in march of 09 and they are still shiny. the scariest thing to me is that the weld was good it was all the tube around the weld that fatigued and broke, meaning weld it back on and it will fail again, also yes they forgot to drill the hole for the j tube before they welded it definitely the cause of the SES light, drill a 3/8 in hole in it into the tube before you weld it back on, or just throw these things out, also a brace to the tube would help too.

Can't agree unfortunately...my Motordyne ART pipes have been nothing short of amazing, I have V2...and I got it used.

Sorry to hear you got a bad one though, if anything they usually get great reviews...

See if its magnetic, that will answer that. And yes, a brace is a good idea for any of these long J tube O2 things! And I just reread and "he" drilled the hole. Interesting. A tune would delete the code anyways so no need to drill it out if you get one. Actually you just need to buy the license for like $180 and have a tuner turn the code off if you can't afford a tune right now.

How many miles do you happen to have on these?

AWSOME cuz I was really looking forward to those ark r-specs there's SICK AND sound great

You'll be fine

I have Ver 1 ART pipes and those things are high quality. I also have a Gen 1 FI exhaust and that thing is high quality.

Sorry for your misfortune.

I was being sarcastic...I love boththese companies, stuff breaks, that a fact of life, hondas are junk too because they break.

"bong" :rofl2:

Sorry OP, good luck getting things sorted.

Update: so yesterday the left side o2 bong popped off. the previous time was the right side. had my mechanic weld it back on. this is the 4th time, iirc, that this pos has cracked on me, and costing more money fixing it than it's worth. really disgraceful for a company. i'm about to look up other pipes.

I had one of my motordyne art pipes crack on one of the welds pretty bad. They also had less than 1000 miles

Full exhaust and low sports cars in NYC has to be expensive. I have not lived in that type of climate for 10 years. I have forgotten what real rust looks like.

My ART pipes are going strong at 1100 miles.. latest revision.

Did you try talking with Motordyne? What do they have to say about your misfortune?

Looks like you're driving it in winter over salt in NYC. No wonder they are so beat up.

I have over 25K on my Motordyne exhaust, still polishes up like the day I bought it. Welds are good to. Have you contacted them about replacements or warranty? I think theres a 1 year warranty on the welds.

I also have always had Motordyne products on my Z and they have been nothing but the best.

^Same with me, my MD exhaust is amazing and has stood up to everything and anything I throw at it.

Sorry about these issues but I recommend contacting Tony as he will be more than helpful to get this sorted out.

Did you purchase these new from him?

That's horrible to see.

Did you try contacting Tony? I'm pretty sure he could've helped you out but not sure if it will be the same case after this thread.

:iagree: sadly you placed judgement practically to the whole company and their products!

Im not saying that you dont have the right to do that being as the consumer. I just hope you gave them the chance to rectify the problem.

I spoke to them before I made this thread. They will not warranty mine because I bought it used from a member here. It's also roughly 2-3 years old.
After the email exchange of being told
I wouldn't receive any help, I linked them this thread hoping they'd chime in but no luck.
Either way, first revision or tenth, it should be thoroughly tested hard to make sure welds are solid and should not have used such sh1t thin metal, especially for the price they ask.
And let's not forget the o2 bongs are closed off, as you can see from my photos, wtf!?

Sorry to hear about your test pipes.
Your comments did bring up some interesting feedback.
From my experience,you can get the same or BETTER product
for less money by going with more of a generic brand.For example,
I've been very pleased with bithe test pipes and,HFC's from
Z1 Motorsports.Their own Z1 brand.I've never had a problem with any
of their stuff.I had their plenum spacer on my 350.It fit/worked
just as well as a Motordyne for about half the price.
You do have to keep in mind of who is doing your install.Replacing&fixing
cats etc is not a shade tree job.THe installer can screw up a good product.

Never planned 2 by anything from 'em. After look'n @ ur POS test pipes it solidifies my opinion of 'em!

Z1 is awesome!

What happened to Motordyne? They use to be very active on here and than disappeared...

Why they would be active?

They were here to show us their products and now there is nothing new to show.

Op purchased these art pipes in 2012 used. They were not in mint condition:

"So I got the V1's off the forum used. There was cracks around the welds on one of them, but it was re-welded at my boy's shop, PetrolWerks."

If you look at the images above from 2012 to the current photos in the beginning of this thread the Ops exhaust has rusted quite significantly. Op stated they did reach out to Motordyne via email and received a response they were not satisfied with.

Motordyne has a 1 year warranty on welds for the original owner: https://www.motordyneengineering.com/pages.php?pID=1 when the op purchased these used he was on his own.

Motordyne has consistently high customer service marks. If you search around here you will see that consistency.
We all have personal lives outside of work. I happen to know Tony has just moved from California to Georgia. I would assume he will be able to focus on "the forums" when time permits. The business operation is 100% if you call customer service or email you will get the same prompt service. Postulating that forums are a relevant arena for customer service requests is silly.


The fact that you guys would even think it is his responsibility to repair these is ridiculous. They were purchased second hand, repaired by people outside of the organization, and have been used in a corrosive environment.

If I bought a pair of Nike shoes second hand, had the sole repaired by a cobbler, and then had a subsequent failure after running through chemicals do you think Nike would do anything for me?

OP, at the end of the day it sucks you have had so many problems with these. Sadly, bungs breaking off of test pipes is common across the board. And when buying used performance parts there is always a risk you will not experience the best results.

This is a super late reply and I understand your point of view, but there has been no answer as to why the o2 bong was covered up with metal.
