currently have the nismo exhaust. which includes the nismo ypipe.

i have them paired up with FI res test pipes.

was wondering if a stock HR ypipe would give me more gains or be the same.

FOR sure i dont want to looses any power.

just seeing if the HR ypipe is an option for replacing my nismo ypipe.

thanks!

ohh dunno if this matters but my car is a DE motor. so i think the nismo ypipe is DE style ypipe? no idea if the nismo ypipe is same style as stock oem ypipe on DE

y pipes are interchangable throught the years of the 350z HR,DE
HR Y is an option...I did this a while back....car felt alot smooth and slight peepier..ehh

The truth

I think the motordyne y-pipe is the only proven one by members here. Others we only go by the dyno graph given by the manufacturer.

I have the OEM HR y-pipe in my DE and as terrasmak said the car did feel smoother and peppier, got it locally for $60 installed so for the money you can't beat that!

I think Motordyne should do a y-pipe shoot out! lol (just like the plenum spacer) plus its easier to swap y-pipe~

can we please stay off the motordyne topic lol


to be CLEAR my question was if i would be loosing any gain i might be getting from the nismo ypipe if i change to the HR ypipe.

The HR y-pipe has been dynoed to show a 5-6whp/wtq gain. I've never seen a dyno for the Nismo pipe, but I have seen people post up that they felt a loss of low rpm power with the Nismo pipe. The affect of the HR y-pipe is completely different. The motor definitely feels meatier in the 1500-4500rpm range. Sounds better too.

WoW?! really.. that is very impressive

i think the whole nismo exhaust give you 6 hp to the wheels.

deng maybe i should change. i have been wanted to change cause the notorious test pipe cracking the nismo y pipe causes.

good stuff

Wait...So I have oem HR y-pipe and recently bought the Nismo S-tune exhaust with busted flex pipes on Nismo y-pipe. Does that I mean can use my oem hr y-pipe with the Nismo exhaust?

I know Nismo y-pipe is 2.5", so the oem hr y-pipe is also 2.5"? Please help out.

iTrader: (14)

well you can use it for sure! is what i have found out.

but just like you i am trying to see if the HR ypipe will make the exhaust setup loose or even gain HP.

at the most we dont wanna loose lol

Thanks for helping out. I'll stop by a local shop today and ask if that'll work.

I've seen a few people with DE motors are trying to get HR y-pipe, and I wonder why?

onagao

Loose = the opposite of tight
Lose = the opposite of gain, find, or win

/grammar ****

Sorry. I have to make that correction, or my head will explode.

Kuhan

iTrader: (17)

I thought he meant "loose", that's why I want to ask the local shop for confirmation.

tw8715

iTrader: (14)

Oops lol

sorry for the confusion haha

it will fit like oem haha

what I mean to say is that if the hr ypipe will cause power loss, if we change it from the nismo

Kuhan since you have both y-pipes, why dont you go out and measure inlet and outlet diameters? I'd imagine any loss of power would be from bottle-necking exhaust flow from manifolds > cats > y-pipe > mid-pipe and so on.

And to OP... DON'T DO IT!!!1

I'm already having enough trouble finding an HR y-pipe. Don't need more people to compete against in the marketplace

Nismo y pipe is Garbo. I would go with HR y pipe if u already have one. And u should def feel an improvement. XYZ is great but fck that price tag

tw8715

iTrader: (14)

soo conclusion. nismo ypipe no good. HR ypipe better.

i have a local selling one for 80. i guess i might go pick up up later
