If you are really interested in the headers just ask if Top Speed makes them. If so they are the same as all the other ones on eBay......which are the same a board sponder, 'delubozparts' sells.......which are proven on the board by butt dynos and 3rd party dyno graphs.

The reason I brought up the CEL issue is the headers replace the existing cat/manifold which contains O2 sensors. I don't see how you could bypass the system (unlike the secondary cats) without disrupting the fore/aft sensors. Could someone please educate me on this?

I know this question has already been asked about other headers and I guess would be the same with these headers....

Using these (or other aftermarket) headers with the stock muffler would make the car noticably louder?

Well no one has had any problems because the bung-holes are still there for the O2 sensors on the headers. So in a way, it's just fooling the sensors into thinking the Cats are still on. As long as you keep at least 1 set from what I have heard, no cell light will come on.

The CEL's can be eliminated in my application ('02 Boxster S) with a reprogramming of the ECU. Basically, you program it has as a Euro spec. car which is only looking for a signal from the front O2 sensor (on the first cat.) and not both front and rear sensors. This set of headers only has one O2 bung which is good for my application as I don't have to add one or block of an extra one.

So do these have the bung holes in them for the 2000+ cars? If they do what do the 97-99 guys do...plug them up? I've never seen a header that claims to fit 97-2004!

[SRQ Boxster]

The headers I received only have one O2 bung, it is located at the rear of the header near the collector.

I'm confused . I have a 2002 S as well and I have a fore and aft O2 sensor on the pre-cats.

SRQ, why does your S only have one on each side???

[QUOTE]SRQ, why does your S only have one on each side???

My car does use four O2 sensors. With this header set I am only going to utilize two of them. Programming the ECU as an ROW car will eliminate the CEL for the missing sensors.
