Y-pipes for AWD sedans
 

My Motordyne y-back is a 3" exhaust all the way back, so I would like to find a y-pipe that merges into a 3" outlet. At the same time, I need a y-pipe that clears the transfer case. Ladies and gentlemen, your help in making this thread the first place X owners come to answer the topical question is greatly appreciated.

Confirmed fits AWD:
Research has confirmed the following fit the 1st gen X:
Unconfirmed possibilities:
I need more information about these brands that appear to fit, but I have not been able to confirm:
Confirmed DOES NOT FIT the X:
A sad state of affairs, but these do not fit:Just a couple of notes about my purpose here.

bump as i'd like to know as well. also, was there a difference in fitment bet x sedans from 04 say vs 05-06?

^I wouldn't think there should be a difference. As far as RWD goes, all of the y-pipes seem to fit 1st gen coupes/sedans/zs just fine. I have come across evidence that the early '04 G35x shares a similar y-pipe design to the RWD, somehow allowing a different style Y to fit underneath the transfer case. I drive an '04 that was made in 11/03, so these x's must be VERY early.

Hopefully I'll get some response to my email later today when the west coast opens for business; otherwise, I'll have to start making calls.

Update for 09 Feb 2010:

- In contact with Tanabe via email; no conclusion yet, but looking for ways to verify fitment

- Talked with AAM on the phone; they are checking with production & design. No conclusion yet, but they seemed interested in finding a way to verify fitment

- Emailed Stillen today

I know dubbedown and I aren't the only ones that care about this - where is everybody?

Great info if only MD made a y-pipe for the x's but thats pushing it. Yea the y-pipes from 04.5+ x's are different than the 03-04 x's

good luck with your search. I've attempted to do my own hunting for the answer and gave up too many variables. In the MD exhaust, we had that one guy with an 04 X post up he had a XYZ pipe and then one guy show clear pictures of his 04x hitting the TC. After that i gave up... I'm taking the easy way out and either going with a stillen gen2 or not getting a Y.


Yes MD COULD take some time in looking at it. I think he did briefly and stated no go. THere aren't any AWD in cali to do any test fitting. Plus we would need a good amount of people interested. I think more of us are interested in suspension then exhaust for the most part. They are/might be in the process of looking at front sways for the X right now. If that sells like expected there might be a chance to look into Y's for AWD.

Has anyone looked up part numbers on the Y-pipes by VIN. Its just weird to have all Y pipes for RWD fit on everything and anything under the sun but we run into something silly like not knowing how far back we need the spot where both banks meet should be to clear the TC. :dunno:

True on the suspension part. Im doing wheels, tires, camber kit, then bodykit. Im still waiting on those sway bars.

MD could, but it will most likely end up being something like us leaving deposits. Dont know if there is a great demand for the y-pipe being done but im all for it.

^I don't blame Tony for not pursuing this. He spent a lot of time designing the XYZ to make sure the collector was at the optimal distance back from the inlets; it just happens the transfer case is at the same distance. MD is all about performance, so there's not much reason to ask them to design a sub-optimal part.

The other manufacturers have been very receptive and responsive to my inquiries, so progress is being made. I don't want to publish any results until I can get some clear answers, but I will be busy this weekend doing mockups and measuring my car.

I guess I thought more people were into exhaust due to the frequency of HFC posts. I can't afford to do all my performance mods on top of wheels, cosmetics, lowering, etc. My car looks bone stock apart from the MD VQ tips on the back - I don't even have an Aero kit. But I ain't skeered - let the idiots in stock Mustangs and tuned Bimmers try what they will...(actually I have no idea - I'm not racing anyone on crappy NJ roads).

thanks... in the meantime, i'm in the look out of a hr ypipe off a 370z. i know those fit the x sedans.

^Yep. Just mind the smaller piping diameter and verify the benefits of that particular pipe before committing to purchase. Check the link in my first post for any updates on the 350Z vs 370Z HR discussion...

any updates? from any of the maybe guys? HR pipes are hard to come by and when they do show up the Z guys know whats it worth to us G owners and want a little more then normal.

Supply and demand owns us all..

This is true.. the 04.5x y-pipe looks like the HR y-pipe, but without the hockey pucks and brackets.

I actually emailed Exhaust Depot about this earlier today (Friday). Terrible timing on my part, as I am sure they are all booked for their private lives given it's a holiday weekend. If I don't hear anything from them by Monday, I'll shoot them another email.

Just an FYI: 2010 G37xS sedan here.

And as far as HFCs, it seems like they should all work. Berk has been the only company to reply back to me, to confirm that their HFCs will fit the X sedan.

My x was built before 04.5 and my Y looks like the Hr as well... weird

Updated with info about the M2 Performance y-pipe. One of just a few that actually fit the X!

I just checked with Tanabe, their Y pipe will not fit the X.

^ sad.

sometimes it easier to say it doesn't fit then to spend time to source an X and trying it.

Hey, great thread.

Any new updates on which Y-pipe options will work, mines beat to **** and I'm not paying 822.00 for a new oem y-pipe. what a joke...atla infiniti toronto

Yeah, I can't find any of these exhausts ether

Can I connect a m2 y pipe that has a 2.5" inlet to my stock cats that are 2" ?

Great question! Anybody know if we can connect M2 to stock cats? I just need a new Y pipe and the 350z option is a tough one to acquire.

Anyone? :confused2:

You should be able to... regardless if you have stock cats or HFC's.. the fitment has to be the same, otherwise there would be major fitment issues with stock exhaust systems.. defeats the whole purpose. :cool:

Subscribed.. Looking for a good Y pipe option

Yes you can - I run stock cats > M2 Y-pipe > Motordyne VQ on an '04 X. I had a muffler shop install because I didn't want to mess with rusted bolts, but they didn't mention any fitment issues whatsoever.

In my opinion the M2 is the best option for me because my y-back section is 3.00" inlet. If you are running stock exhaust (2.5" inlet or so), you might be better off with a stock pipe since you might run into rasp issues with larger diameter going into smaller diameter.

For me, going 2 to 2.5 to 3 is ideal. Once I put the M2 pipe on, I finally felt like my car was "complete," and apart from the occasional rattle exorcism, I haven't modded since.

sorry for the massive late bump, I noticed AAM Competition was unconfirmed

Well let me confirm that it DOES NOT fit. We had an X customer come in and it does not clear the TC

So I may be a noob, but how can I tell if I have a 04.5 or an 04? Because I know there are some differences in what can fit.... correct?

biggest differance is that the 04 used the old style y-pipe.. looks like a "T".. in the 04.5 they began using the Y-pipe that looks like the HR Y-pipe, but without the "hockey pucks" (vibration dampers).

This can be confirmed by comparing the 04 vs 04.5 Tech Manuals. the 04 shows the "T" pipe.. the 04.5 shows the "Y" pipe.

will the m2 hook up to the coupe middy I have a 04x with the coupe middy and hks rear?

I have the same question, since I literally just bought both the m2 y pipe and the coupe midpipe....

Did it fit correctly?

It fit perfectly. The exhaust installer had it done in 15 min

So I would say it would fit the stock G35x mid pipe then without an issue. Would you agree?

So anyone looking for just replace a bad Y pipe, could go with the M2.

Yeah it would definitely work. My kit even came with replacement gaskets.

Why would you want to replace stock y-pipe on 2004 g35x if it is basically the same as HR other than upgrading to stainless? New here and looking at upgrade options. :)

So which design did you guys install...

by looks i assume #1.

agreed... #2! :biggthumpup:

So I need a new y pipe due to mine rusting out and making a rattling noise.
After I reading this thread I am still not sure on if this M2 Performance Stainless Y-Pipe Exhaust w/ Flex 2008-2012 Infiniti G37 VQ37VHR
will fit my 2006 G35x or not.
If not what Y pipes can I use?
Thanks.

Bosal now makes this part
 

Okay, so now Bosal has JUST released (last week) the proper direct fit Y-pipe for the G35X AWD Sedans. I just spoke with a Bosal rep and he said the pipe is direct fit for 2004 and 2005 G35X Sedans.

The part number is 750-547 and "list price" is something like $370 but he said it will be significantly cheaper at the resellers. It's very new so none of the resellers have it in their catalog yet, but they have 10 of them sitting in their warehouse in NJ and resellers should be able to get them by calling directly.

any pics available anywhere...?

nevermind.. just found it...

Attachment 205545

Yup. Just ordered it from NAPA locally and they quoted me about $170 for it. It comes from the Bosal warehouse in NJ. Most other places either can't or won't order it because it's too new and doesn't show up in their catalogs.

I'm really glad they came out with this, the only other direct fit option was the OEM or this one for $280 off ebay: http://www.ebay.com/itm/2005-iNfinit...662daf&vxp=mtr made by Fast Line Muffler

I looked at the picture and $370 seems pretty steep. And for that price I would assume that they could pay a halfway decent graphics person who could competently operate the "Magic Wand" tool in photoshop.

I smell troll

Troll? The part is on Bosal's online catalog.
Like I said, $370 was "List" Price.
I got quotes from $160 to $230 from actual local resellers (NAPA Auto parts in Herndon, VA and Olympus Auto Parts in Alexandria, VA) to special order it.

Either way, just thought this info might be helpful to others, since it's a brand new aftermarket part and dealer price is about $500.

HA!.. yeah.. this pic shows some really weird bends and kinks along the length of the pipes between the flex joints and the collector... kinda makes me nervous! :)

I have an 05x and my ypipe is rusting out and i'm looking at the M2 VQ37VHR, will it fit? I have a Megan Racing OE-RS and stock cats.

Yeah.. I do believe it should.. the wide Y shape of the HR style y-pipes clears the transfer case on the X's just fine. The Motordyne Y-pipes won't, the down pipes are too short and come together to the collector right UNDER the Xfer case.. FAIL!

I ended up getting Fast line muffler (from Toronto) pipe
http://apicdn.viglink.com/api/click?...hid%3D14376916

And it fit my 04 G35X Sedan just fine. Cleared the transfer case just fine. Almost identical to the OEM pipe. Bosal's pipe wasn't stocked in any warehouses locally and would have taken a week to arrive.

how's it sound.. any rattle/buzz issues...?

None so far. Put about 500 miles on it.
