RacingLine Header/Y-pipe

[Racingline]

Here is the dyno graph, I apologize ahead of time for the grainy image. the shop no longer had the original runfiles do to a computer crash so I was forced to MS paint the 2 together. I'll post an updated back to back dyno when we have the chance to run a new one

updated product image with cleaner welds, the previously posted was the "production sample":

[mcheddadi]

at low end is there half the torque and HP or is that like a glitch ?

[blackteam02]

245hp WTF?! learn-me guys, Learn me! what are we lookin @?

Yeah whp is less than crank hp , that's normal. The thing to look at is the diff between the baseline stock and the v2 y-pipe

I don't know why it would be half, but I could definitely see it being lower than stock at the low end due to loss of back pressure. There has got to be some sort of reason that Nissan designed the original Y-pipe with such a dramatic "kink" in the pipe. I love how much low end torque my car has, I would hate to lose all of it for high end gains.

l was referring to the dyno chart just above...

[emprbasist]

I know, I just meant I'm surprised it is half of the stock value, but I'm not surprised it has decreased.

From looking at the dyno it says "Stock" for the first pull, was this completely stock?(No intake, no exhaust nothing)

What is the V1 you have on the second pull? Version 1 of the pipe maybe?

[blackteam02]

. . . i dunno man, im puttin' my purchase on hold for now because of the DRAMATIC drop in HP and TQ @ the lower end of the charts. . .

We'll have to wait and see the results when everyone gets theirs installed, & i hope someone has the Artisan exhaust already cuz im curious if this Y-pipe remedies the (((droning))) issue!

there is no dramatic drop off. the dyno operator doesn't go WOT until somewhere between 3k and 3.5k rpm. The differences you are seeing all depend on when he hits the gas. on each pull.

He hit WOT before 3k on the stock pull but not on the Y-piped pulls? Why the difference in test parameters? I guess its hard to compare the dyno results then. I would think you would need to run all dyno pulls at the exact same condition, WOT at the same RPM, same temp and conditions and same operator, in order to be able to compare these. For max power and torque they work just fine as they are shown, but the full powerband comparison would be nice to see.

now that they are out and on thier way to everybody, we'll try to set up a time with another local ( stock) car for a new test. that way we can get a cleaner looking dyno graph.

Somebody just got their Y-pipe installed.....

ME!!

My Car feels/sounds beastly... Recently installed a K&N also.

Very impressed with the pipe. Adds some volume and Rasp. May have to install a resonator. It's pouring rain so can't really tell but the weather and humidity affects exhaust volume.

Just like the previous version it adds power across the spectrum. Awesome!__________________

[rcboy514]

hey rich, are you running the stock exhaust? also did you notice any fall in torque off the line?

thanks

+1 on these questions

i just ordered mine through a local shop ... cant wait. really curious how it sounds with a stock exhaust ><

[rich2342]

Ive got the borla axle back, but with the y-pipe and intake my car sounds beastly...

everything is increased hp/tq it feels right through the entire rpm range.

Only thing is the rasp. its similar to the z's with test pipes. It ruins the sound of the borla somewhat.. Definately added a few decibals of sound over the stock y-pipe. May have to throw a resonator on

Think you could shoot a little vid? I love the sound of my Borla right now and I'm curious as to what it sounds like after the y pipe. I don't want to ruin that beautiful sound.

+1 for Vidz!

Thanks bro, those were great . Especially at the end of the second one, I was waiting to hear the sound at high RPM. It did change a little bit but not too much, so that's good to hear (no pun intended). Looks like I will be ordering mine shortly. Thanks again!

[gearhead05]

And... order has been placed! Also, if anyone else was planning on picking this up, the code "4GALTY" for free shipping expires today so you should order today.

[EzeebMOS3]

Sounds sick man!

Glad to see there's another Boston guy on here with mods

[rich2342]

Thanks man,

I want to get it up to New england dragway a do a few runs.. Never been want to see if i can break 13's probably will require practice

[rcboy514]

Sounds SICK! I can't wait for mine to arrive, i'll try to get some vid of it with the nismo cat-back

[Importroller]

Ok, now for me, I didn't really notice anything different at first today when I was on the highway heading to the meet, but on my way back, I had more stretches of open freeway to open it up a bit. And I noticed something. My biggest gain was acceleration from mid RPM range all the way to redline. So from around 3500-6800 rpms, my car is just accelerating faster and faster through every gear. I run out 1st gear a lil quicker now. Sound wise, I can't really tell if its louder since I still have the stock resonator. But I can definately feel the increased TQ, and on the highway the higher TQ combines nicely with the HP and just pulls the car along faster.

Wow sounds really nice...

[XXplosive990]

love the vid, n damn cant wait for mine to get here ahhh hurrry up fed ex lol

Yah man I've been wanting to get up there for so long. I'm gonna try to go with some friends soon once it's nice out.....

I'm curious if the CVT will let me get into the 13s
