What?? LO how does that happen? Well if he still has it, refer him to this thread. Maybe he can help one of our fellow G members out

Euro, if you're going to pay 435, you might as well grab MD's XYZ pipe instead for a few bucks more. I wouldn't pay more than 150 for the HR Y pipe used.

Check some junk yards too for wrecked HR Zs...you'd be surprised what's salvageable and how much you'd save this way. I mean the pipe itself can be in mint condition

 

oh man hell no im not buying a y pipe for that much but yah i'll probably try the junk yard

 

I sold 2 of the 3 I had to members on this board for $110 each shipped. The price included $45 for shipping from Texas to Cali, so I didn't make much but I was glad to help a couple of our brother's out.

Putting mine on this weekend. Will let you all know how it turns out. I installed the MD 5/16" spacer last weekend, and wanted to drive with it a week before I put on the y pipe. Also needed some time to figure out which one I wanted to keep for myself Looks like any of the 3 would have worked out OK!!

 

Does he still have it, Still got his info?
I had a seller fall through on the my350Z site yesterday for an HR ypipe.
I'll pm u.

 

what a mess with all these different pipes, i wouldnt mind a stronger low end, so maybe ill try to find the one with the 1.75" inlet pipes

 

Mike,

From everything I've read, any of the ones mentioned here are an improvement over the stock t-looking pipe. Which one is the best seems to be a matter of opinion.

 

Wow. How'd you luck out and find 3 of these at once?

 

Just lucky I guess I struck out at the Nissan dealer though.......

 

I don't know about the pipe measurements given here because I measured my stock Y-pipe and it measured 2.25" in the inlets and 2.5" at the outlet. As a matter of fact, I used the stock flanges to make my custom y-pipe and did not have to modify them because I used 2.25" piping for the inlets and 2.5" for the outlets. The only reason why I even made a custom Y-pipe was because the OEM was not mandrel and because it had very tight bends.

All pipes were measured with a very accurate caliper so no mistake was made. Could I have had ANOTHER style y-pipe?

 

Could it have been 2.25" OD (outside diameter) inlets, and 2.5" OD outlets - making it around 2" inlets and 2.35" ID (inner diameter) outlets?

The only measurement that I am certain of is the G37/370Z Y pipe. All of the other measurements I listed were taken from info given by other members, and speculation based on similar Y's.

I actually have a stock DE Y pipe in my garage and an OD tape, which will allow me to get an exact measurement. I'll measure it tommorow so we'll know the specs on it for sure.

Hopefully we can get all of the info for these Y pipes in one spot. Please let me know if you find any other discrepancies in my post.

 

Piping is supposed to be measured OD, which is what I did. Don't know how others did it though.

 

With heat shielding aound the pipe it is hard to get an OD, I agree that does give the most acurate measurement though. All of the measurements made so far in this thread, and DaveB's, have been ID at the flange.

 

My measurements were eyeballed with a tape measure and were inner diameter. They are in no way scientific and exact.

Hope I didn't confuse anyone.

 

I see..I cut the flanges off though do it was easier for me.

 

Damn so many different pipes.

So the one on the Left is from the G37/370z?




Motordyne have done testing and larger piping is better then the smaller 1.75inch, so I am going to keep looking for the 350z HR Y Pipe
