are dc 4-2-1 headers street legal. if not, which ones are? also what's the dif between teh ceramic coated ones and the not coated ones? thanks

 

yes they are. they have the carb# welded onto the header. difference between ceramic and stainless steel is the the SS last longer (what i was told). also when SS heats up it changes color.

 

yes they have a metal stamp/plate w/ a CARB EO# on them.... their street and smog legal... the diff between the ceramic coated and stainless is one is made of mild steel and ceramic coated.. and the other is made of stainless steel.. however once their used for a while the shiny stainless will turn brownish/orangish/purplish/bronzish whereas the ceramics pretty much stay greyish...

no performance differences... about $100 in price difference.. and the ceramics might be a better insulator of heat...

 

thanks for the quick responses. which ceramic should i get?? http://www.modacar.com/products/Acura/Integra/MODAHEA/

it looks like there is a one piece anda 2 piece..which one should i order? i'm planning on getting a jr supercharger and a stock type r exhaust

 

if you plan on supercharging, check out kamakazi (sp) header. Heard good things when they are put together.

 

I've rather leave my car unlocked and alarm off in a ghetto area...

maybe push my car off a cliff....

shoot myself in the foot right before a race...

than order something from MODACAR.. just my opinion....

 

yeah thanks for the tip but there are just so many mixed review.
https://honda-tech.com/zerothread?id=281775 i just posted that and some guys are sayin its not worth it. i thnk i'll go w/ the dc 421 just incase i don't get teh superchager. but should i get 1 piece or 2 piece?

 

Do not know of any performance difference from 1 or 2 peice. 2 is easier to put in, but 1 looks much cleaner. I had the 1 peice 4-2-1 SS on my car.

 

2's easier to position/install Lolz..

 

Sorry GSRaCeRbOI, thats the second time I beat you to the answer

 

and? *shrugs*

 

nuttin. i am just bored at home

 

Yes they are street legal cause they don't do **** for performance.

 

inteGSR- what year GSR do you have? I have a used DC 4-1 ceramic 1 piece header. Used for about 10K miles, but in excellent shape. No dents, scrapes, cracks, rust or anything like that. Looks good as new besides the fact that its dirty. If youre interested email me : jt240@aol.com ....im from napa.

Also, the 2 piece is barely easier to install and is heavier. the 1 piece takes like 5 minutes longer to install and is much lighter. let me know if youre interested

 

i have a 94 gsr. it seems that the 94-99 use dif headers than the 00-01(?) i thought the integras are all the same(?) yeah i'm interested in your header. what's the main dif in performance between 4-1 and 4-2-1?

 

inteGSR- yea, the exhaust manifold is a bit longer on 00/01 gsr's i believe. the dc 4-2-1 i have is for 94-99. its off my 97 gsr. 4-1 gives you gains from 4k+ rpm, but i hear it loses a bit of power from midrange.. the 4-2-1 have less PEAK hp gains, but has provides power and torque more thoroughly throughout the powerband.
but yea, if youre interested drop me an email: jt240@aol.com Like i said, i'm looking to get at least $200 for it. its in damn good shape. what city are you from? letme know whats up

 

i'm around pinole so i'm close to you. the thing is i don't spend that much time above 4k so i'm trying to find a good deal on a 4-2-1. if i can't find one maybe i'll buy yours

 

****!!! my bad dood.. i just realized that i posted that i had a 4-1... I HAVE A 4-2-1... my bad.. let me know if your interested.
