Gauging Interest: 2.5 liter headers

[noshift]

any updates for the sedans? stillen? crazyitalian?

[Datalux]

I can tell you the header bolted right up without a problem (new flange) and is quieter than the original prototype that I ran for a month. Very nice addition over all.

hey noshift, i am trying to get these bad boys installed, i just added my sway bar and i freaking love it!!!

and now im trying to set up an appointment at the mechanic shop

i want these on so bad!

[dldjros69]

Nick you are driving me nutz get this bad boys installed already.

i cant wait any longer.

I had peoples in my car this morning and they loved the sound of the header.

[crayzitalian3]

its most likely getting done sometime during the week. what im trying to figure out is how the sedan flange works.

for whoever installed the flange for the coupe how does it work with the exhaust clamp, im so confused.

someone explain the flange part and ill be set to go

hey datalux how exactly did you install the flange, thats the only part im stuck on and then this is getting installed

thats why i said the hell with it and just use the bully dog tuner to erase the error.

[crayzitalian3]

i know but i want to play it safe and just do it, or else this would of went on a while ago

I guess I should qualify that statement "the mechanic who installed my header said "the header bolted right up without a problem" It's 105 deg. here and I wasn't about to lay in the driveway for 2 hours in this freakin' heat.

On a separate note, anyone have any heat concerns regarding the proximity to the transmission and lack of heat shields?? I know my intake temps went from the 140's to 150's on a really hot day.

[crayzitalian3]

so he didn't leave you with any info on how he did it?

also could the heat shield go back on or no?

[Datalux]

No, In fact I'm wondering if he did it right.... He said he didn't need the wire to extend the sensor and after talking to someone who has already done this, I understand that is nearly impossible. So I'm wondering if I'll be throwing a light in the near future. <sigh>

There is no way the heatshilds are going to fit the new header, sorry.

[dldjros69]

Those heat shields bolted directly into the header. So i they arent going to fit as mentioned above. Im not sure if there is a heat issue or not.

The 1st o2 sensor does not need to be extended, its a tight fit but the wires can be stretched.

Im not sure if you can extend the 2nd o2 sensor, i totally skipped that step.

Do you have an aftermarket intake installed? I'm curious about the intake temps.

[crayzitalian3]

throck, are you going to be getting the header?

[dldjros69]

K&N - not in traffic

If its 70 outside the intake temp its about 81. it seems to be 11 degrees higher.

I pulled over one day looking at a map on my iphone. i was there for about 5 minutes. It was about 90 degrees. Hot and humid for PA. My intake temp went up as far as 125 degrees. i drove off and the temp came down with in a minute or so.

this maybe a real dumb question, how did you know your intake was that hot? cuz im in az and summer here are well in the 100's

[Datalux]

Yes I have a K&N intake installed as well as the Bully Dog GT Tuner which is what I'm reading the intake temp from. In the cool mornings temps range 70-80's.

dldjros69 - when you say "Im not sure if you can extend the 2nd o2 sensor, i totally skipped that step." are you saying you don't have both sensors post cat?? Are you getting an SEES light? Mine went on this morning on the way to work.

Are there 2 sensor post cat??? i thought there was only one down there. (im guessing i have what you have minus the flang thingy.

But i didnt use the flange or the bung hole thingy.

Yes i get the SES light every 25 to 100 miles. Except this time ive gone about 200 miles since the light has come on.

I use the bully dog tuner to clear the error code.

Yup, two bungs for the sensors on the flange post cat. Odd, my Bully Dog gives me a blank screen when I go to Diagnostics and I have an SES. Seems to be a programming issue with the JA05E....or I'm doing something wrong.

[dldjros69]

At this point you are speaking out of my league. Id give bd a call and see what the problem is...

what???

about freaken time

nice vids (more to come later im drunk)

[dldjros69]

I didnt notice it last night but in your third video it was really loud.

What a change over stock!!!

What cha think of the power gains?

[crayzitalian3]

its very noticeable i love it man, next i want the stillen exhaust because i feel that the nismo one will be way to loud with the headers because there is no resonator

[bhs07c]

Speaking of the whole header/exhaust combination..I have a custom MagnaFlow set up and now that I've installed my headers and lost a CAT, my exhaust is so loud that the mufflers actually start to vibrate violently at high RPM's. Is there anything an exhaust shop could do to tighten up the hangers or something because it sounds horrible...

Besides that...the 2.5L Headers ROCK!!!!!

Great gains (Without any intake manifold back pressure, it sure feels a lot more open and smooth).

Awesome sound increase and exhaust tone improvement

Sweet under the hood looks!

Awesome job Stillen
