Is the rest of your exhaust stock? I have the same issue with my G37X Sedan. The Megan has a 3" outlet instead of a 2.5" outlet. Do you notice more drone/rasp as many experience going with a 3" outlet Y-pipe with stock?

Thanks!

 

Everything else is stock. Car sounds stock

 

With a stock exhaust, mainly stock cats, it probably won’t change much. The further away from your engine the lesser the change, unless the part was R&D’d to alter sound. If you’re running HFC/TPs that step down turbulence will be amplified compared to stock. Rasp mainly due to increased airflow, drone from a less muffled tone.

Unrelated to your comment, but related to this post; I wish I knew this wasn’t actual 304 SS before I bought my Megan Y-pipe a week or so ago. My plans were to buy a 3in to 2.5in step down, the longest-smoothest length I could fit, hack the exhaust and weld it on. Living in the salt belt and this not being actual 304SS, this isn’t worth the effort.

If I can’t return / restocking fee + shipping will be more than I can resale for, I’ll have a BNIB Megan Y-pipe for sale before the week is over. If you’re in the market, I can probably save you $20-40 and eat the cost. Otherwise they’re just re-taping this box and resending it to the next buyer and further profiting off their false advertising...

 

Does have any records of this being true? Would a typical exhaust shop be able to test the SS series without damaging the part? I don’t know a thing about testing SS grades, but a quick google search all involve something acidic in contact with the part, and that seems like a cause to void a refund.

I’m not doubting your claims. I’m salty I bought something falsely advertised and their listing needs to be adjusted or removed. There’s a big difference between poorly constructed “Ebay quality” to actual false claims regarding structural material.

If someone can provide proof, or point me in the right direction to obtaining proof, I’ll put the effort to have these listings updated so consumers know what they’re getting. I have a “rep” I go to for issues. I don’t think he’s a rep, he’s probably pretty high up, but he’s investigated everything I’ve challenged that ended up being illegitimate.

This needs to be addressed if their advertising isn’t accurate. The G market isn’t going away for a while.

 

When I was researching the Megan Y-Pipe the other day it seems many people have issues with the flex pipe leaking or even fully breaking apart within a year. :c/

At this point I am thinking to just swallow the price and upgrade to Stillen CBE, especially my mid-pipe is also rusting out and will probably need to be replaced in less then a year.

 

Forgot about this. Ill do it tomorrow.

 

Thank you. If possible could you provide a picture of your read-out? I’m likely returning the one I just bought if it’s not 304.

 

Curious as well.

If its worth anything, the one i put on almost 2 years ago still has no rust.

 

The Megan Y pipe is not made from 304SS.
It is made from a somewhat "equivalent" material with higher strength, lower cost, and similar corrosion resistance.
At this price point, I am sure both the materials and labor are sourced in China.
You will see that material is both, not 304SS, and is also slightly out of some chemistry tolerances for what the PMI gun thinks it is (Nitronic 32 and 201SS). If the material comes from China this does not surprise me.
The theme with the selection of these materials is low nickel, low cost. Nickel is expensive.
Here is the breakdown.

Nameplate



304SS Basic Chemistry for Reference.



Flanges are strongly magnetic and come back as high nickel. These will no doubt be nickel-plated carbon steel.
I am surprised they plated these in nickel considering the low nickel theme of the rest of the materials.





All pipe and Y fitting is not magnetic and comes back as (almost) nitronic 32.






Flex Portions comes back as (almost) 201SS. Again, if Chinese material, I am not surprised about chemistry being out of tolerance.

 

^^^^ that's what i said many times. Good job and thank you for confirming. 200 grade stainless. It is garbage. It could work in warm climate, but where road salts are used... forget about it.

 

Oh wow, good to know. Hope mine continues to hold up...

That tool you have is super cool, I didn't even know such a thing existed.

 

Yeah I got access to some cool stuff at work. That unit cost about $25,000.

 

Thank you for putting in the effort and detailed contribution.

I’ll be returning mine today. I’ll press hard on Ebay to do something about these listings as well. False advertising doesn’t sit right with me, especially when it’s the product entirely.

These have been sold for years assuming they were 304 SS as described and I haven’t seen actual data to prove it false. Most of the market buying an Ebay Y-pipe do not have access to a $25k reader, or just accepting you get what you pay for lol.

If anyone cares, I can add any important updates regarding their Ebay listings. I’d just avoid this **** though.

Thanks again Jaydee23.

 

great work guys. So does anyone know of another Y pipe that is not a Megan? Looks like my driver cat has a rattle inside, y pipe is getting a bit cruddy too. I'm thinking high flow cats and 'while it's apart'

 

Solid work. If anyone contacts and gets a reply from MR, please post it up. I was anticipating the metallurgy would be somewhat off chinese steel, but using completely different steel than advertised on the flex and flanges is pretty unforgivable.
