am i the only one with these?

ok guys heres the deal..... got the headers on wed. took em to a performance shop fri and they put em on. the install only took 4hours (MAX) no more (closer to 3).... i had a few shops quote me 8-10 hrs for the install. the easiest way to put these on is dropping the engine craddle with the front and rear mounts.... while having the engine hoisted up some with a stand..... by removing this the install was MUCH easier....

cons: the exhaust is LOUD.... when i say LOUD i mean LOUD... i have a RT high flow to a 2.5" b-pipe to the HKS rear section.... NO resonator. at the rpms range of 1k-3k it is unbarrable.....if u dont want alot of NOISE dont get the headers. thats the only dislike..... except the price....

pros: the power increase is DEFINATE! pulls like a deamon up top.... the sound of the exhaust at WOT is insane i love it. i still havent felt the full potential of the headers bc my car is still lossing power around 5k rpms.....

i got a resonator put on today and this made a BIG difference in the sound.... still LOUD but not as LOUD im considering a few different exhaust setups to get this thing a lil bit quieter....

i have pics of the install but i dont have a good host. any ?'s............

will

FYI- dont ask me to dyno it..... I WILL when i fix the power loss problem

 

Now experiment with that exhaust setup we discussed.

 

Your stock muffler would probably keep it pretty quiet. Maybe just change the tips?

 

can this header be mounted up to stock exhaust system??

 

i shelled out alot of MOOOOOLA for the HKS i would like to keep it but if not i might sell it.... SR20DEN ur idea is great definately gonna give that a try... thanks for the idea man!!!!!

will

 

On a 2002-2003 A33.

 

So basically the install was under $400, which is good, right ?

No ses light ?

Are you doing a dyno anytime soon ? If so, please post the dyno results...

Lastly, can you tape while in the car, at idle and then at wot ?

**excited**

 

 

*****Are you doing a dyno anytime soon ? If so, please post the dyno results...******






dude read the last line of my post....... the install was $225 got a damn good deal..... had a few places say $700+..... video prob wont happen bc i dont have a digital video camera if someone in the atl area wants to record and host one then thats fine with me.

I will be your host.. luke@vqpower.com

 

thanks for the offer sr20den is in the process of doing that for me!!! thanks for the quick reply!!!!

will

You car just lost aout 40 pounds or so. That will help plenty.

 

 

great to hear someone got the headers on!!!! now I want them more, but that LOUD thing kinda scares me. definatly would like to hear a recording of it. Also, a dyno would be cool, but if you feel a gain from the butt dyno, i'm sure the headers do their job. Congrats on gettin them on!!!

 

Also, what'd you hafta do with the O2 sensors? Did they have a place? Welded? SES light??

 

damn...finally someone got the header on...u are probably the first one buddy...congrats man...i want them too...yeah but the noise issue could be a prob for me too...since i got the obx exhaust which can be pretty loud thru 15k-25k rpm range....but anywayz...everything is looking good...and keep us posted on this....thx

 

I wonder what would happen if you combined the headers with the ECU upgrade.

 

The tire companies would love you.

 

Damn dude you got a high reving motor. Did you get the new ECU to bump up your rev limiter to 25,000? j/k man

 

Hmmmm...what if you added a 50 shot to the picture?

 

Piston companies would love him too...headers usually make our modern vehicles run slightly leaner...

 

that would be delicious

 

That wouldn't stop me. And if adding headers really does lean out the majority of the cars then Technosqaure needs to be aware of it. Each new bolt on or combo needs to have it's own program

 

i want my ECU and headers! nice pics!

 

bump the fp

 

This is sweet, the ECU w/headers is going to give atleast a 50hp bump (flywheel ofcourse) back to back 13's would be a sinch for you 6spd guys. As for the autos, well low 14s would now be acheived but SR is 100% correct when he said tire companies would love you.

 

I have one ... remember the video of the STN MTN meet? well that was my camera and gtr edited it and hosted it...let me know...it aslo depends on how far you live..i live in east cobb ( marietta )

 

sweet i go to southern polytech during the week..... PM me with ur telephone # and we can work something out so everyone car hear it...... people say that im being overcritical with the sound but its def ALOT louder..... maxima gurgles at idle kinda crazy sounding!!!

will

 

sweet setup Will

 

Damn, this sounds good. Keep us updated.

BTW, are you willing to share the exhaust setup you and SR20DEN discussed?

 

PM sent

 

Headers+CAI+Exhaust+ECU might get you around 290 - 300 hp. This sounds quite sweet.

 

with the addition of headers and ecu

 

Maybe at the flywheel, but not at the wheels. 350Zs with Crawford intake plenum, Technosquare ECU, intake, and headers are only putting ~270rwhp. As we already know, the 350Z is putting down 240rwhp stock or about 30whp more the Maxima. Stillen only claims 15hp with the header kit for the 2k2+, at least according to the catalog they sent me.


Dave

 

this alti is putting down almost 250 WHP. not sure if this has been seen before, but it would be nice to know if $tillens #'s are close...


http://www.nissanperformancemag.com/...ltima_headers/

 

Still an interesting proposition.

 

Lemme ask you something.. You say you plan on getting the "power loss" fixed... How can you hide them nice, shiny headers from the dealership? hehe

 

before the headers my very last dyno was 228hp and 234tq at the wheels SAE corrected..... hoping for 245hp 250ishtq! think its possible?

If u guys want me to dyno please please please help me fix this 5k rpm power loss. the ECU throws the SES lgith and the code is P0507 Idle control unit...... any help fixing this will be greatly appriciated and will also get the dyno numbers for u guys!!!! thanks in advance!!!!!

i dont go to the dealership.... screw them! i have the 100k warrenty and they denied me warrenty work so **** EM!!!

thanks for all the positive feed back guys!
