RacingLine Header/Y-pipe

[Hussain]

i saw the other guy's time slip on the other board and he ran a very high 13.8 and i ran a very low 13.9 (mine was a 13.912, almost the lowest 13.9 you can get) and with some practice, i'm almost positive i can hit a 13.8 also. also another thing is that the guy has been racing for a while, he said he had another track car that he races.... keep in mind that i'm 21 and got my license at 18. i didnt race at a track until about a year ago. i mean the guy did a really good time, i'm not going to dispute that and he DID beat my time. i just think that with some more practice ill hit the same time.

AND AS FOR LESS MODS: he had an intake (which i dont have), plus something to blow more air to the intake (forgot what he was saying about something custom made), exhaust, and a Y pipe.... all i had was no muffler. i still had all my cats and everything stock. the Y-pipe eliminates the cat and plus he had exhaust so that should make it dead even right there BUT he still had an intake and something else which i don't have. so i think he has more mods then me. he also used the excuse that the coupe is like 100 pounds lighter.... well, stick shift is like 100 pounds lighter then CVT so no weight advantage for me (plus i got hella fat now... 206 pounds ).

both of us did good and all i'm really trying to say is that the guy (as well as others) belief that i had more mods is false. in actuality, he had more then me, as well as having more racing experience.

[Importroller]

you are talking about JK who did a 13.4 the other day. He was on drag radials. And yes, he does have more experience racing cars, but not FWD cars. and one thing so many of you guys forget is that what one car does on one track is not what that same car will do on a different track. so many factors come into play from weather, to track conditions, elevation, etc...

for your times, its misleading because you post as though you did that run stock, when in truth you didnt.

[XXplosive990]

some tracks are just DEAD evil, lol come to the fontana speedway on august first and see what you get there. Theres tracks where you'll grip on the launch as if you had glue on your tires or something. Tons of factors come into play with track times. but i ALWAYS get way different times at different tracks.

[Importroller]

Fontana is not good for off the line unless you have slicks or drag radials. I know on a better track i would be in the lower 14s or high 13ss on an ideal track. Fontana is really hot due to location so running low 14s there is about the same as running high 13s to really low 14s at an ideal track

[Hussain]

ya i agree. he had similar track conditions as me (low elevation, low temps, etc). and from day 1 i always said i got those times with no exhaust on. but he also tried to down play his car and say it was almost stock and the best time for an altima with the least amount of stuff done to it which i dont think is true. i'm not saying i'm stock (i never said that) but i think my mods are less then his.

and to everyone sad about your track times, dont worry about it. i ran a 13.9 two times with no muffler and even 14.0. but i went one day where it was about 100 degrees out and with no muffler, the best time i pulled off was something like a 14.6 in the 1/4 mile. temp makes a HUGE difference in my opinion. my friend went to the track today and was trying to get me to go and i just told him no, i'll just save my money because its pointless. ive been to the track before so its not something new and i already know that the hot weather right now will only make me run crappy times.

[XXplosive990]

yeah lol 105 degrees AT fontana and i got a 15.0 once with a really good launch and everything. That heat KILLS though, at that point i gave up on gettting good times it was just about beating the other cars lol

[Dexion]

The real difference is the trap speed. You both ran 13.9 but you're trap was 99mph and his was 102-103mph, thats a big difference. You can only use the driver excuse so much since all you really have to do is make sure you launch right and let the CVT do its thing.The manual driver has more to worry about.

[Hussain]

when i looked at his slip and my slip, i had him the whole way down the track and at the end i got a low 13.9 and he got a 13.8. so it just goes to show that the stick shifts weak spot is the launch and the CVT's weak spot his going past 100 MPH.

[RobPaulson]

until you post better trap times.. I will say that the manual is overrated and = FAIL... doesn't matter whether or not its true... if its not true, you have to prove it buddy...lol

oh eff that... where is a track around CT? I need to go and post up some times and rep for the damn 6MT's! Donkey Kong time son, Donkey Kong.

Sick time import, god you guys sound like your having so much fun at teh track i wish this stuff was more popular in the northeast!

Well, there is this one in NH that I'm going to soon. Man they even got grass drags for snowmobiles up there. (which kick a** btw)

if i could find that huge jaw drop smiley, i would post it right here

The 2.5 does not have a Y-pipe. It is an inline 4 cylinder.

th

does anyone know if the y pipe is the same for the CVT and MT with the placement of the o2 sensor and all? or do we need to specify which transmission when ordering?

[Importroller]

you don't do anything with your O2 sensors. The Y-pipe is the same fore CVT and Manual

[el_blacky06]

yup everything is the same on the exhaustand id thought the 3.5s do way better on the track than high 13s i ran high 14s at 94 mph with headers,intake,pulley, and my friends bullydog tuner, took off seats and no spare tire. and i took off the exhaust to run open headers. dat got me 14.799 best time so far

[Hussain]

didnt that sedan also have magnaflow exhaust? or am i thinking of a different car?

[el_blacky06]

how does flowmaster sound on our cars anyways? i got flowmaster on my sedan with cat delete

[el_blacky06]

wait i meant how does magnaflow sound on our cars lol (now i feel stupid)

Thats a good time. If the 3.5SE has some proper tuning than we will see some better times, also traction without good DR's is always going to be a bottleneck in getting to that quarter mile mark fast enough.

Now if a 3.5SE had the same mods as you do (he only had Y-pipe/Intake/mufflers) than he would probably be doing high 12's on DR's BTW his best time to date was 13.2@104mph

The bullydog tuner doesnt really give me the power where I want it on the 3.5SE its more of a boost on the 2.5S but we have a real reflash in the works now.

[Viper5000]

I think I want to get this pretty soon.... has anyone actually received everything that you are supposed to get with this??

Or better yet:

JOE, what additional items are supposed to come with this part?

[Racingline]

The Ypipe comes with the necc bolts for installation, the only thing you need to pick up is some RTV copper gasket sealer ($5 at your local parts store)

[Viper5000]

thanks Joe if the money gods are on my side, I might be ordering a y-pipe very soon.

[Viper5000]

Sweet, my Racingline Y Pipe just got in..... CANT wait to install it this weekend.

I appreciate that everything was included, and they even threw in a free hat

[ScKcBc]

I have one of these racingline y pipes for sale, if anyone is interested. I'd like to get $200 shipped for it, it was over $300 new. E-mail me at [email protected] if you're interested. Thanks!!

Just got his y-pipe on the car last night. Instantly noticable change.

Anyway, I'll be heading up to new england dragway tomorrow night. A few of the guys here at work go up there every couple of weeks or so. One of them has a Titan with a bullydog GT and an exhaust and is calling me out ( ) so... I'll be posting timeslips sometime thursday.

[CoupeVQ35CVT]

I have an '09 Coupe 3.5 CVT, with this Y-pipe, as well as a catback exhaust. I did head to head races 0-70 mph and 40-100 mph roll, against another STOCK CVT V6 coupe, and frankly the results were less than impressive. My coupe with $600 in bolt ons had no advantage from a stop. From a roll it seemed like my coupe was SLOWER, as Cj's coupe was crawling forward, until about 80-90mph when I noticed I was starting to gain and beat him ever so slowly.

I never noticed anything much after the Y-pipe install, other than some sound change at higher revs, and now after the head to head comparison, I can see I gained nothing to write home about practically, or what I'd call "noticeable," but maybe the y-pipe doesn't like the catback (how that even matters makes little sense).

I think a few people are too optimistic/susceptible to the placebo effect of having a new mod and thinking something's gotta be faster. I really hoped this was a 'magic mod' myself, but it's clear to me what this is worth. After even a fully bolted Altima Coupe + BGT tuner in other several races only just beat me by a few mph, I shouldn't let this lack of "wow" bug me too much. I like the sound, I guess it's one 'noticeable' change.

This may be so. When I installed the y-pipe, it sounded and seemed to feel "different" in that the engine rev'd seemingly quicker. But, I'm not sure of a few things with this car since my excursion to new england dragway last night.

1) My first run of the night was my best run of the night. 14.5xx and that was with a bad 60 time and a little bit of wheel spinning.
2) I had big problems with getting those hankooks to hook up at all last night. Spun every time out of the hole.
3) On the runs where I had less spin, I found that since the CVT heated up so much, it wasn't working very effectively. Maybe its just mine but something was slipping and I consistently was getting 15's even as the temperature dropped during the night.
4) This car definitely limits the throttle around 80 mph. It was noticeable by myself and a friend who i let drive the car.
5) If you don't let your car cool down A LOT, you end up with real bad results. For anyone wanting to go to the drag strip with any frequency, look into getting a transmission cooler.

All this being said, I'm confident that if you could get this car to launch (without breaking the cvt), then you could absolutely pull low 14 into high 13's with this car.

My last two runs of the night, something very weird happened. I'd launch, run down who I was up against, and then right before the 1/4 mile mark I would get tossed forward. It was like the CVT came out of gear and then shifted down once. I did this twice, the first time I did a run with traction control on, so i was wondering if it had something to do with that, and the second time i had it turned off. My belief is that the CVT Control Unit tells it to "cut the crap" once it gets too hot. So i listened to that and didn't run any more, but this is how I come to the conclusion about a transmission cooler.

[Ranga14]

Yeah, the transmission cooler does wonders. Just be sure to get a gauge to go with it to keep track of the temps.

A reflash would also help with the throttle issues. A real one that is.

+1. His car's CVT oil stays at around 180-190*F even when stepping on the gas often.

[IBCoupe]

I gotta wonder if a transmission cooler wouldn't help all around for people who are aggressive drivers, though they may not be on a strip or a track.
