if i was to remove the 2ndary cat close to the muffler...
will CEL turn on/?

Yeah, it probably will. In layman terms the sensors that were aft of the cats will sense too much pollution and think your cats are not functioning properly so there's a good chance it will trip a CEL light.

Che has totally disappeared from this site. I guess business is good.

That's too bad because like many others on this site I am interested in his headers but not without having the questions posted on this thread answered first regarding the CEL's

Thanks Che, I just ordered a set of headers for Boxster S on wednesday. I bought the 97-99 style from you 2 years ago but i need the O2 sensor bungs on the header. Will you be making Secondary cat. bypass pipes?

You are welcome William, Your order was shipped out on Wednesday. I've included couple O2 Sensor CEL Fix Adapters with the Header purchase Free no charge, hope these will work for you. Right now working on the Secondary bypass cat for 97-99 & 00-04 Boxster & Boxster S should be ready around in January or February 2011, will Post updates as soon is ready. Thank you for Business & Support

For all international customers reading this monster thread, I am from Australia and ordered a heap of things off Che:

Headers, cat back, adj. rear track arms and a short throw shifter.

He gave me a great price on the parts and a top shipping price (considering the size of the box)!

It arrived in a week, was packaged perfectly and all parts look fantastic. Really looking forward to installing them.

Get on board Aussies!

Che,
Well I received the new style headers & I am disappointed in the new style flanges. The flange transition to primary tubes is the worst I have ever seen, (I used to sell headers at a warehouse distributer speed shop) also the collecter to secondary cat pipe 3-bolt flanges are thinner & have elongated universal style bolt slots not oem style holes. Oh well I need the dual O2 sensor bungs per header for my 2000 Boxster so I guess I will have to give up some exhaust flow due to poor tube fitment to get the O2s on the header. I shipped them off right away to get them ceramic coated inside & out for $170. This will retain more heat inside the headers to bring O2 sensors up to temperature quicker & limit radiant heat to engine compartment. Headers came back from ceramic coating & I finally have time to install them, sold my 97-99 style TopSpeed headers for $100. New headers are harder to bolt to engine due to tube routing but I get it done then realize the O2 BUNGS ARE ON THE BOTTOM of the collector facing down & there is no way the wires are long enough to reach the connecters. The bungs must be on the top of the tube facing up for the wires to reach not to mention to prevent a loss of ground clearance. As I start unbolting them to put my stock maniflods back on I notice the PASS. SIDE DENT for engine clearance is in the wrong spot & has no effect other than to block exhaust flow. Great I have $400. "invested" in useless ceramic coated pipes & I just sold the last set I bought from you.

Thank you and My apologies on the issues you had experience,

No, he's been on here. he just hasn't posted a repsonse here. I clicked on his profile and it said he was actually here today @ Last Activity: Today 09:19. My guess is that he doesn't have reasonable solution to the CEL issue so he hasn't posted a repsonse.

so a better solution is probably to keep the cat by the muffler...
and remove the first cat along with the headers?

would that be better?

Here's the deal. If you want to avoid a CEL then you need to keep your stock manifolds or pay $2,300 for the Fabspeed headers I listed a pic of. The other main cats down stream by the muffler can be removed because there are no 02 sensors by them. Essentially the computer doesn't know if those cats are there or not. Here's a pic of the stock Porsche manifold that che's headers replace and all the others on ebay like his. If you replace this manifold with one without a cat then a CEL is likely. This is why companies like B&B don't make headers for 2000-04 boxsters. They know it will cause issues. The 2.5L guys however are in the clear and don't have to worry about all this stuff.

oh i see!! thanks for the explaination. so the secondary cat ( by the muffler ) is save to remove and replace with test pipe... but there have to have a cat by the exhaust manifolds... i see...

[CJ_Boxster]

Steve... Im going to hit you!

You cant remove any of your cats without getting a CEL... You can remove the secondary cats IF and ONLY IF you have ROW settings flashed into your ECU or have revo flash your ECU to ignore the input from the last sets of o2 sensors.

If you look at the image, the cat on the right side has an O2 sensor screw in behind it so its expecting cleaner exhaust.

This is where the o2's are bolted to my exhaust on my 2.5.

That diagram has me scratchng my head! It shows 8 02 sensors!! That diagram is screwed up! You should be able to replace those cats no prob.

That image is from the porsche parts cataloge, its just showing all the possible locations an o2 sensor CAN go.
