DC header ?

The ceramic coating is literally peeling and flaking off on the downpipe. Mainly around the o2 sensor. Is this normal? I have gotten coolant on it before and was wondering if this was the cause.

I just dont want it to start cracking or anything

Most headers will do something like that over time anyways. DC's are usually pretty good on how they wear even the ceremic ones. However you shouldn't have to worry about it cracking anyplace it should be just fine.

dow do you like the ceramic coated header....I bought a lightspeed one that was just stainless....I wasent too sure about the ceramic coated ones.

I've had my dc header for about 3 weeks on the b16 and it's already dulling. I could care less though, I just want this thing to roll.

I really dont know. It went on when I swapped in the ZC so I really wouldn't notice the difference.

Plus my ZC really isn't running all that good. Maybe you guys can help me with this-

my idle sticks around 2500- 1500. I think this is because I'm using the DX throttle (too long) cable because I can get the idle to drop down by bringing the gas pedal towards me with my foot. I've been told to get a 88 teg throttle cable, but there are no junk yards around here and i dont know where else to find one. Is it possible to take out the DX throttle cable and shorten it.

it also drops down to like 700 then back up to 2500-1500. (up and down, up and down). It did this before because the idle was set to high. I adjusted the idle to 750 and it was fine for a couple of weeks, but now its doing it again. The idle screw is all the way down. The car also smokes a little when doing this.


Gas mileage is extremely shitty. I think i'm getting around 160-190 to full tank.
Any help would be great.

Just bring this post to the top
