Product: DC Sport 4-2-1 one piece ceramic headers.

Distributor: ebay

Vehicle: Honda Civic 92-95 (DX/EX/LX/SI), Honda Civic 96-00 EX Only, Honda Del Sol 93-97 SOHC.

Cost: Since it was ebay, $255 shipped. other sites will run from about $270-$300+.

Installation: It was very easy. Need socket renches and may need WD-40 for rusted bolts.

Installation time: took about 30-45mins to jack the car up, take off the stock, put the new ones on, and bring the car down.

Review: First i want to say some bad things. since my car is 10 years old and have never change the stock headers, the o2 sensor was a big problem. I had to take the stock headers to meineke to get it off and i had to buy a new one cuz the threads were gone. Other than that, the headers were easy to install and are amazing. I could feel a huge power increase. They are also waay lighter than the stock ones. They look great too.

i have this header, it is very easy to intall its about 12 or 14 bolts that you have to put on, it was cake....

 

I have the jdm ITR 4-1 header. Its a really nice piece but its still considered one of the worst performers compared to the likes of Spoon/T1R etc...

 

I have the DC Sport Header. Its not bad. I dont have any complaints about it.

 

Where is the O2 sensor that is usually located near the front of the engine (on a stock 2-piece, iron exhaust manifold for a D15B7)?

 

the stock o2 is pretty visable from the front but with this header, it is relocated under the car fairly close to the cat. the header came with an extenstion wire to reach the new location so there was no problem with that.

 

If the O2 sensor gets moved to another location, doesn't that affect the fuel/air ratio. Did you have any issues after installing the header with the O2 sensor in a different location?

 

after installing the header the engine began to idol very oddly. its been about 6 months and it still does. when i start the engine it first idols at a lil over 1k, then about 5-10min later it goes just under 1k, and then when the engine is warm and idols, the needle is all the way down as if the car was off. I cant figure out what the problem is, i got an intake, did a tune up and everything and still idols weird. i cant say for sure if the location of the O2 matters but i figure it shouldnt. i think i need to reset the timing or something.

 

have you tryed resetting the ecu

 

ya i've done that and no luck. i doubt its the sensor cuz i had that replaced with i installed the header. i really dont know why its doing it but everything seems to be o.k. been about 6 months and no problems other than wacky idol...
