Sped force racing 3.5L custom headers... $1099

[rjdmmfl1]

Hey guys, just to let you know, speed force racing is ofering their custom headers for $1099 for the 3.5 Altima Coupe... I will speak with them today to explain why this costs so much (since its dual headers) and why theyir product is superior to the competition (if anyone ever decided to make one) Right now, I belive this may be the only headers available for the 3.5L

NICE! the headers thought didn't die out. hopefully it will be CARB legal or CARB pending cuz it's a pain in the *** to do headers on our cars and if you get pulled over and get sent to the ref, you're screwed. only thing though, wasn't stillen thinking of making headers (but didn't do to the lack of interest) for $600 but they said it would cost probably $1,000 in labor just to get them installed.

[rjdmmfl1]

OK, with the 3.5 , if you get pulled over, and they inspect you engine, they aren't gonna see the headers... I don't know about being CARB legal, by the time I would have to get an emissions check, I will be outta Cali ... but seriously, I can check with him about being CARb legal...

I know they create theirs so that the O2 sensors don't trigger check engine lights... just thought I'd throw that in there

I don't know what STillen is doing, but I do know that thy already have the headers built for the 3.5 in the 3rd gen Altimas, he stated that the fourth gen Altimas would be difficult to build, just a beyotch to install

they stated that a good shop should be able to do the install for ~ 600, but that to do the headers righ would cost ! ~1000 again, don't know about Stillen, this is speed force's cost

the point is though, speed force is ready start selling these as soon as folks want to place orders... but again, who's really gonna shell out $1600 for this? that remains to be seen... from my experience on NICO, a lot of folks ask for things, but mum's the word once its time to pony up the dough!

I will probably do this, but it is going to be awhile before I have those kinds of funds to blow on headers. I have alot more important things to buy first.

[RobPaulson]

are headers as minimal of a power gain as exhaust/intake?

the greddy exhaust im lookin at is around the same price range, but it has a HUGE sound/look factor to it, if this is just a hidden +3-5HP then it would not be worth it for me to do in the near future. I would be interested eventually, but im just trying to plan out my mods . . . it seems like i would get more out of the exhaust if these headers arent offering a pretty decent power upgrade.

so any insight on the power gain from this? any other benefits than power? Will it sound much different?

[Hussain]

what i've seen with headers on other cars is pretty significant gain, somewhere around double what you would get from exhaust. also headers have a good sound upgrade. look at it this way, the air is release from the engine through the headers which then go to the Y-pipe and then the exhaust. if your stock headers are choking it up (which 90% of the time they are) your exhaust will still be choked up...... exhaust can only improve the flow as much as the headers will allow it to so restricted headers mean restricted flow

[LongBeachCoupe]

Yeah.. from my understanding its one of the better gaining products...

Think of the exhaust as a river...If the opening of the river is narrow, it doesnt mean anything if its wide later on, because it cant get there as fast... if that makes sense lol

It didnt think greddy made an exhaust for around $1600????? All I know is now we need a cold air intake, then combine that with headers, y-pipe, and exhaust we will be seeing a pretty decent gain of HP.

Do you guys think with all of those we may be able to beat or big brother the G37. Or even with the short ram intake or AEM

[AltiCoupeDriver]

As for exhaust vs. headers, the headers are definitely going to show much better gains, a lot more than you could really hope for with an exhaust. However, I do agree that if you get custom headers you might as well get larger diameter piping to increase airflow, as well as a replacement y-pipe. Much like Stillen is making for the 2.5(a headers/b pipe combo).

About our cars beating a stock G37, I think we might get close with I/H/E, and a tune to get the best out of those bolt-ons, but I think it would be hard to close that 60hp 12lb-ft tq. gap.

[spockrock]

I don't think we'd come close to an extra 60HP from bolt-ons. But the person who can better answer this question I think is Blake or some of the other guys whom have been squeezing performance out of their cars. The only thing we have on the G's is we are ~400-500LBs lighter but that's it.

[EzeebMOS3]

I'd definetly think about getting these headers, however it would not be until Spring....mainly because itd take me that long to save up that kind of cash.....plus id figure around 800 for the install just to be safe.....is the header design the same for the CVT?

Also would it be compatable with the y-pipe made from Racingline? I'm gonna get the y-pipe from them as soon as it is available...

Plus would the headers void the warrenty, as well as make it impossible to pass inspection/emissions tests? This is a main concern because with the y-pipe it would take under a half hour to install the stock pipe to pass emissions, if the headers dont pass...than were outa luck

[Hussain]

we'd beat a stock G37. with my muffler off i ran a 13.9 on a cold day. warmer day i ran with and without the muffler (cat-back exhaust with no 3rd cat) and only saw a .1 decrease in my times.... also when i did that 13.912 i had my car ON. so on a cold day with the Y-pipe and exhaust i think i can hit a 13.9 and thats without HEADERS or intake or tune....... go look up the G37, the think weighs a billion pounds.... all that power and it only does a 13.9 or i think someone got a 13.8 with it..... i raced a G37 on the street one night with my exhaust and no cat and he barely got me. with headers, Y-pipe, exhaust, intake, tune..... you'll beat the G37......

[adidas2go]

Lol, bro, get off the 13.9 story already. OLD NEWS! Anyways, I agree, IHE will get you beating G37's buddy

[LongBeachCoupe]

Grandmas g37 though right? I mean, anyone interested in "testing your speed" most likley has SOMETHING done... Its a big gap to close... but if you add one of those fake BOV's off ebay i think its in the bag! $10 to the guy who writes a DIY for it!

[adidas2go]

No,

The G37 has 50 more hp, but weights 400 more pounds. In general speed calculations, it takes 10 hp to offset 100 pounds. So, all in all, it has around 10-20 more usable ponies than us. IHE combo would give us an edge on the G37. Now, drive train comes in HUGE with this. The race outcome would be different between the 6 spd/CVT A/C, and the 6 spd/Auto/RWD/AWD G37's in their particular scenarios.

[Hussain]

lol i'm not stuck on it, just just shocked that the G37 only did a 13.9, which is what i could do with just an open exhaust cut-out or with my exhaust on and with headers and stuff

[Importroller]

Ill stop down there this weekend and see about test fitting for the Sedans

uummm they dont, i said around the same price because the greddy exhaust is 1024.85 from stillen, thats pretty close to the 1099 for the headers. I didn't take the install into account because i have a good family friend (mechanic) who is willing to help me out with this (aka do it cheap).

and i just want to comment, the sarcastic and malicious undertones of this forum are getting rediculous lately . . . yall need to chill the F out, this forum is losing its original 'homey' feel that was ever present when i first joined.
