Y pipe otions
 

So, was thinking on just buying a kit from summit racing or simular and fabbing up a Y pipe, but noticed a few options out there that are resonably in expensive, my ? is do some of the 03-06 350Z Y pipe options fit on to the 370Z? I noticed that a few offer fitment for 03-06 350Z and 09 370Z upward.

Any one know for sure?

I think I may just bite the bullet, if its too long I can cut it, too short I can add to it, for the saving it makes sense....

Appreciate.

I am also interested, just finished the install of my CNT Racing resonated test pipes on Friday and the size of the tubing of the Y pipe reminds me of my Honda days. Even my buddy who was helping me said he thought it looked small. Definately let me know what you find out, as I would greatly appreciate it!

Will do dude, cheapest Y I have found for the 370 is low 400's, granted a nice piece but the choice for the 350 is vast and you can pick them up from 100 bucks delivered for unknown brand to 125 delivered for a megan racing etc, man for what it is as long as it is 2.5 in and a 3in out I am happy.
I am ordering one today and will make it fit, for <100 bucks to my door its worth it, I am just going with a cheapo OBX version, that way I dont care about cutting it up if needed.
If the welds are not that great a quality I will just redo them.
Will report back, it will be a couple weeks as out of USA currently, hence my surfing for new projects to get busy with when I return ;-)

Thanks, looking forward to hearing what you come up with and if the 350's Y pipe fits w/ no modifications or what not. Have a safe trip back.

Hey, I just did some searching on ebay and they have some y pipes for the 370, and one is a OBX for $170 and $30 dollar shipping. I don't know if you are going through OBX or Ebay or where but maybe it will work without modification. Just a thought.

Also, I just looked at them side by side OBX vs OBX and they look quite different. Again, just a heads up.

How come I missed that... ;-0 looks a resonable pipe for the price to, I will look into it today when 'working'
Thanks on return

so whats the result? is the 370z ypipe the same size as the HR 350z?

Found a Y for 370Z 2X 2.5 to 3in, 190 shipped to my door, currently on vehicle and doing ok.

hows the sound and fitment? Was it worth it or better to wait and save for a full exhaust system? I'm really interested in how it sounds, a vid would be great if you have the time. Thanks.

^ Ill post some vids up over next week or so for sure... it sounds sick, especially with my SRI , at redline it screams, down shifting is super

Thread revival: Which one did you end up buying? OBX?

Also, what are the stock dimensions and how rough are the transitions and bends? How sh!tty is the OEM collector?

Just trying to decide if a Y-pipe is really worth it, even a relatively inexpensive one.

Old thread but here is the info, I went with the OBX, fit fine , went well, I feel the stock Y is pretty restrictive.
Here is a quick video for sound, this was with TP's

looks good man, i just received my JIC y pipe today, my system will be complete. the only thing left to do is stillen headers... is it really worth it?

^ I had a set and sold them on with out fitting, I think they can work with a specific tune.
TBH if I change headers it would be to feed a hot side ;-)

Hmm -- cool -- okay, I think I may just pick up one of these if the fitment is good, because they're pretty cheap.

I'll be getting a baseline dyno soon, then dyno wit htest pipes, then one with that + intakes, and will do a separate one for all of that plus Y-pipe in due course.

Sweet man, nice to see people putting effort in to proving stuff,,, you can actually get a pipe a little cheaper on ebay right now, I was one for 160 + 20 shipping, looked much the same.

Working on it anyway -- test pipes just came in the mail today :D

On that note -- do you know if anyone is selling just two tailpipe + muffler sections that will bolt up in lieu of the single OEM muffler?

^negative - I would have helped you out but recently sold my spare mufler that could have been a donar.

Rats. Well thanks anyway :tiphat:

Hey, actually, do you know or could you find out the angle and diameter of the OEM pipes before they join into the OEM Y section?

I was thinking I might just pick up a really nice 2-1 merge collector (maybe Burns?) and weld that on in place of the factory join.

A nice smooth transition right there might make a difference without having to replace the rest of the piping.

yo just installed my JIC y pipe, man the sound is deeper i love it. throttle response is better and the torque is definitely back in the game.

Nice -- where'd you get it and how much?

Is the OEM Y-pipe 2.5" to 3" too? If so, the high quality collector might work pretty well.

I think 2.25 to 2.75 dude, sorry , missed previous post

No problem -- hmm. Would you mind checking that if it's off the car? I am seriously considering the collector idea.

I would if I was there, its on car right now, but from memory that is correct, maybe Westwood can measure his stocker? I would whip it off but am in St Louis for another week ;-(

yep 2.5 inlet/outlet and 3" in the middle! and man i love how it sounds.

got it from ebay MSRP $547 paid $268+80$ shipped fed ex! my buddy couldn't beat that price and he owns a speed shop i think its the prefect match for my top speed axle back. throttle response and torque is very good. but most of all the sound is deeper almost exotic im very satisfied :tup:

Cool! Glad you like it :tup:

If the OEM Y-pipe is off the car, would you mind checking the diameters for the inlet and outlet pipes for me? :tiphat:

its 2.5" for sure :tup:

2.5 into 3" or 2.5" into 2.75"?

Or are both in and out 2.5" -- that would be fairly restrictive...

It is into 2.75 I believe. I know for sure it is not to 3. Our Y pipe has the same Inlet/Outlet diamaters as a HR350z

Some one prove it :tup:

Nobody has one off the car to confirm the measurements for me...? :o

No rush... but would be greatly appreciated and worthy of rep points of course :tiphat:

Trust me dude lol

OK I'm confused LOL

What size are the stock Y-Pipes, and are they the same on the Nismo?
2.25" or 2.5" inlet - to - 2.75" or 3" outlet.

I'm getting a JDM Y-Pipe (2.5" to 3"), which I'm sure is a direct bolt-on.
Am I going to gain anything now from getting a 2.5" to 3" Y-Pipe ??

Is the 370z OEM exhaust same as the G37? If so, I had the same question for my G37 and here's what I've found out so far:

Exhaust diameter question re: Berk HFC to OEM mid pipe - MyG37

I'm not sure the stock Nismo exhaust (NOT S-tune) even has a Y-pipe.. right??

The Nismo has an H-pipe according to Nissan:
"NISMO-tuned dual exhaust with H-pipe configuration"

Yep -- see here

Great answer thanks :tiphat:

Guess I have a spare Y-Pipe for sale now, dammit..!!

Which design yields more power, the Y-pipe or the X-pipe ?

x-pipe = more top end power from what I've heard
