Dansk headers

[emeer]

Hi,

I have fitted dansk headers to my 01 boxster (us spec). As predicted the cel light went on because the the "header cats" are now gone. Im doing a remap next week and my dealer tells me the remap will take care of the cel, is this correct ?

re mapped to euro norm 3 standard will do it. at least it did in my track 986S. it will never pass a US emissions test this way.

Thanks. Does that mean that the re map will effectively disable 2 of the 4 sensors ?

No - it changes the standard by which it will throw a CEL - you will still have to have your secondary sensors plugged into the harness - it is still looking for a signal, just now it can sniff pure mountain air or the air in China's QuanDong province and not throw a code. You either wire tie them nice and neat, or insert them into your mid pipes if you have a place to do that - I did - My primaries sensors are in the headers (no cats) and my mid pipes (also not cats) had a place to take the second set of 02 sensors - so it is nice and neat under there.

Looking at a picture of the Dansk headers, it looks to me like there are two holes - the first sensors go in the first hole, and the second set in the second. Hard to tell for sure, but that is what it looks like on the dansk website.

Thanks again, sounds like this will work out fine once I've got the remap sorted. You are right that the dansk headers have two predrilled holes on each side, so there is no extra work involved in getting the secondary sensors plugged in.

Btw, I like the headers so far. Better mid range and throttle response.

emeer - one thing I forgot to mention, and can't believe I forgot. Some of the larger diameter headers are dangerously close to the power steering line on the drivers side. Be sure that line is not touching your headers. This happened to me on track once. The fire, which was quite small fortunately, melted wiring for the camshaft sensor and the 02 sensors on the drivers side. I was lucky.

Thanks, this was mentioned to me when I bought the headers and I now use a small spring to keep the servo line seperated from the headers.

Im also thinking of wrapping some heat insulation around the line just to be sure!
