Motordyne quality.
Hello fellow VQs, I want to ask all the fellas who bought motordyne exhaust help me with a problem. I recently purchased motordyne ART pipe and XYZ pipe because of their outstanding rep. Well I received them and was really excited. I open the box and briefly checked the outside for blemishes or shipping damages but everything was shiny and looked good. I put it aside for a few weeks because of finals, I didn't want to put them on my car just yet.
Well tonight I went and took a look again, but this time inside the piping and I found something. As I was checking the XYZ pipe I found that the merger was a little bit odd. Take a look for yourself.

So I inspected further.



And this is what the top looks like.

Now tell me I'm just crazy **** and everything is okay, cause I feel like it's not motordyne standard. What do you guys think. And btw not bashing motordyne I just want people opinion on this cause I don't want the hassle to send it back and forth if it's nothing. I just want it on my car but I still want my money worth of quality and performance.
Also my ART pipes have oil on the inside. Is this normal? It's the dark color behind the helmholtz. It is throughout the whole pipe except for the very ends where it looked like it was cleaned.

This is all hand made piping, specially the y-piece is a bastard to make it fit exactly.
I've been TIG welder for years so i can understand the work, i would have used a pencil grinder and removed it, which you might be able to do yourself if it bothers you.
The oil you see inside is most likely from a pipe cutter which is cooled by a mix of water and oil, the water dries up leaving a oily substance behind but that will burn up :-)
Maybe this one slipt pass the quality control because normally all Motordyne equipment is how it should be.
But if you install it like this you don't have to worry about it.

Oil isnt an issue. I dont like that y-pipe merge though. Only heard positive things about motordynes customer service so id contact him if you dont have the means to grind that down yourself.
I've contacted Tony. Hopefully I get a new pipe or a refund. I don't think I can live with it. I payed money for a performance pipe even if it makes minimal impact on performance it is still not optimal.
I showed my non car people friends and asked them what is odd about the XYZ pipe. They all quickly noticed the protrusion.
I've contacted Tony and asked if I can return this piece for a new piece. We went to email to show him the pictures. After looking at it he said it is fine.. And that was it.... Not giving up, since I don't want a deformed Y pipe on my car even if it is little of effect I said "I understand the negative effects will be negligible, but it still don't have the high quality standard that I thought you'd employ. So it's a no go on a different Y pipe?"
Annnnnnnnd no reply. I wasn't rude was I?
He seemed to respond to my first email of the picture rather quickly.

I wished I did my damn research on Motordyne quality as of late. I run his MREV and spacer and it was phenomenal and he has like literally NO bad products back then. I then went off to the world of bikes moving from a 2004 Yamaha R6 to a 2007 Honda CBR 600 and kind of left my G hanging. Since I sold my CBR i had this extra cash around I wanted to spend it on exhaust and tune for my G. I went with Motordyne never researching because of the quality product he put out before. Then a few minute searching and

post#44 exactly true. You see A LOT OF SCUFFS ON A BRAND NEW product. The flange and the actual piping is ludicrously off.. well take a look. Compare it with the FI HFC in that post.....
(stretch marks)


(that alignment)



And notice how its pretty much all in like 2013.
Welp learned my lesson.
Wow... That kind of finish is not what one would expect from a well-reputed company. My Gemini looks better that those LOL.
My buddy's Art Pipes also cracked after putting on a few hundred km's.
Nonetheless, those pics you show are very tiny flaws. It won't be noticeable once you put it on and most importantly won't affect your car's performance at all... IMO.

post #44 again and read his third input.
"MD coats their parts in a ceramic finish. Why? To hide flaws? If you look closely, you can see scratches/small creases throughout the resonator and piping. The ceramic coating assists with hiding this to the customer visibly."
I'm not going to lie. I overlooked them at first until I read that very post I whipped out my ART pipes to check, and then brother have I opened up my eyes
Take it however you want it. If you have his product and you enjoy them, then good for you, but I'm not running these **** pipes on my car. Hopefully my input will help new buyers on their decision making.

That's the feels I'm having lol. I've already decided to return both these pipes. I'm going to return them and probably get fast intentions. The side by side comparison of it and the art pipe was day and night. The piping and the flange are sanded together to be 1 piece vs the motordyne circus like tilt.

i have that art pipes and the tdx2, and nothing wrong with them. i do get what you are saying though. remember that tony himself doesnt make them, he contracts them out to companies to make. the scratches are prob from the mandrel machine and not a biggie, the little lip isnt going to affect anything at all.....instead of returning it, post it for sale in the marketplace and then you wont be out the shipping back to him

But that is exactly why I wanted to bring this to light. So he can make improvements on whoever he's dealing with. I don't bash him personally. It's just his product isn't up to his old standards.
I bought from b2auto. I called tony and hes not exchanging me new pipes. I will return it to b2auto for a refund less the shipping price.

When I spoke with Jason on the phone he said the tube length was "a bit off" on his XYZ pipe. I asked him to send me pictures via email so I could see what he was referring to and we would take it from there.
This is our email string. Read it from bottom to top.

Hi Jason,
Yes, you can return it for an exchange and we will send you a replacement.
There is nothing wrong with your XYZ pipe, it is within normal building tolerance. If you would like to send it in for an exchange we can do that but what you have is a standard production article and there will always be some degree of part to part variation. We have a higher quality standard than any other manufacturer for the Nissan and Infiniti community. If you were to compare this Y pipe to any random production Y pipe from any other manufacturer you will find the Motordyne to be the best. But that doesn’t mean a negligible or inconsequential part to part variation can’t happen.

Hi Tony, this is Jason. Sorry I didn't introduce myself, but here are the pics of the XYZ pipe.
Hope that is enough photos. As I said the right primary is a little bit off when it merges.

Hi Tony, this is Jason. Sorry I didn't introduce myself, but here are the pics of the XYZ pipe.
Hope that is enough photos. As I said the right primary is a little bit off when it merges.
The XYZ pipes are hand built. When the fabricator cuts each of these tubes it goes in a cutting fixture and is then put into a band saw for cutting. There is a normal amount of tolerance and tolerance stackup. Tolerances are based on the application and requirements.
Some tolerances are based on functional or dimensional requirements while others are based on asthetic requirements.
In the case of this XYZ pipe where Jason wrote "the right primary is a little bit off when it merges" is as shown in the picture above. It is not however going to have any effect on performance or sound. This is a way overblown detail that amounts to nothing on the function, look or fitment... but we will exchange it. I always want Motordyne customers to be happy. That is our #1 priority. So I offered to replace it for him. So far I havn't head back but the offer remains open.
If a Motordyne part breaks we will warranty it. Just show us what the warrantied problem is and we will replace it. We always will. We will even go through a trouble shooting process with you to help figure out what the root problem is.
If in a case like this where a (new/unused) part has nothing broken, out of spec or defective and it will look and perform perfectly once installed... we will exchange it for you anyways. We want to keep all our customers happy.
PS - As for the "stretch marks" on the elbow of polished tubing. That is what happens when you mandrel bend tubing. All the time. No matter who the manufacturer is. Friction is part of the mandrel bending process. The mandrel bender slider is put up against a straight tube where it is pressed very hard against the tubing and forcibly bends the tubing around a radius while sliding against the tubing. The mandrels are covered inside and out with heavy grease to minimize the sliding friction but this is simply part of the mandrel bending process.
You will only see this on the outside radius of a bend. Not on the inside radius of a bend and not in the straights. Only the outside radius of a mandrel bend. That is how the mandrel bending process works.
Additionally, we polish our parts. Polishing can make a part look great but it can also make fine details or blemishes in the metal finish stand out and more apparent. The mandrel friction grooves for example. If the part was not polished (like some of our competitors), the mandrel friction would be much less visible but they are still there. Motordyne parts are polished and overall they look far better for it.
We dont weld our flanges from the inside to save on time or weld wire. we weld them with weld wire entirely through the outer circumference. It is stronger that way. And the reason we had ART pipes cracking in the prior generation of ART pipes was because it was a completely new application for perpendicular tube welds that experienced very high temperatures and vibration. For axial welds its no problem. For perpendicular welds there was a new learning curve to it. And we will keep improving all of our products indefinitely. We also changed the one year warranty to two years. And to be consistent, the warranty is 2 years on ALL Motordyne exhaust parts.
If you ever have a problem or question with any Motordyne part contact me. (661) 993-5111 We will help identify the root cause and if the part is broken or defective we will replace it.
We stand behind our products.
DAAAAAAAAAAAAAAAAAAAAAAAAAAAAAANG, that just happened. I can speak first hand about dealing with Tony, I had the muffler on my TDX2 crack along the front seam, I emailed him about it and he stated that he would warranty it out for me no questions asked after I sent him a pic of it.
