Jordo! · 08-12-2010, 12:25 AM

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

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

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:

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"

Great answer thanks

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

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

Boost_lee · 08-20-2010, 04:01 AM

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

Abdiel · 08-20-2010, 11:46 AM

Kinda makes you wonder why Nismo went with H instead of X like almost every aftermarket CBE vendor.

christian370z · 08-20-2010, 01:13 PM

From the testing Stillen performed, they found that a Y pipe design yields the best gains on this car in both hp and torque. I personally think that choosing between an h pipe/y pipe/x pipe is splitting hairs on a performance based view point, but the sound they produce is different.

I believe you'll also have to change the mid pipes if you want to use a Y-Pipe on the Nismo.

Not sure there any any real cheap solutions here guys.

As someone mentioned at the point of changoing the downpipes and mid-pipes, you may as well go all out, and just get a full cat back that performs better than the Nismo LOL

Plus you should through in some Berk HFC's

christian370z · 08-23-2010, 06:22 PM

Just measured my stock Y pipe for you guys... My measurements for the inlet and outlet diameters of the stock Y pipe are as follows:

Cat to Y pipe: 1 3/4" for both inlets of the OEM y pipe
Y pipe to axle-back: 2 1/2"
