New Headers for my '04 S

[Jaxonalden]

I read an old post from CJ Boxster and in it he had a IPB (illustrated parts breakdown) of my exhaust system. The picture showed a place for an O2 sensor aft of the secondary cat. If its there and I plug my O2 sensor to that I should be able to operate without getting a CEL, right?

The picture of the exhaust system in post 254 on the Thread called "Performance Exhaust and Header for Boxster".

i dont have to worry about that... cuz i have a 2.7

ummm im not exactly sure what will the computer sense or detect...
because after eliminating your secondary cat the air flow increases and
the chemical fumes changes so im not sure what it will do...

my mitsubishi is easy... i replaced everything straight pipe
no worry

Yes, I saw that in the diagram. I don't recall seeing 02 bungs before and aft of the secondary cats on my car though. There might be a place to tap and drill a set. 2nd issue with that is your wires for the 02 sensors arent' nearly long enough to stretch back that far so you'll have to cut and splice some extensions. I heard that can backfire because the longer wire has more resistence which can cause a CEL as well. Did you install the headers yet? Let us know how they work out.

Why cant someone download and copy the DME program from a European Spec car (no CEL with no Cats), and then email it to the USA and we can download and flash our american DME computers to avoid the Cat delete problem?

just wondering,

Headers are going on this weekend as long as my 'ol lady will allow me the time. She gets pissed when I go do "fun stuff" instead of watching our 1 year old son. The swap shouldn't take that long. I'll see about the wiring on the cats. If worst come worst I can always swap back and just be out $150. Better than paying $500+ for a system I can't use. I think of this way, it cheap for me to test the pipes and even cheaper for those of you waiting for the results.
I can't wait for my Durametric kit to get here. The website says I'll be able to monitor real time parameters as well as all codes to include the triptronic. Also all overrevs. Best thing is I'll be able to help my local PCA members in case they have problems.

As I have stated on other posts, the ROW program is on the PST/PIWIS, you just need to find someone to map your ecu for you.

What does it take to map the DME and change our cars to ROW? Will the dealer do it? Aftermartket Indy shop?

As I said in my past post, I needed time this weekend to do the install. Well I found the time last night between 10pm and 3am.



This is the set before install



Drivers side OEM set



Both OEM sets removed and ready for the install



Drivers side installed, looks great and the install was fairly straight forward.



Now for the bad news. This is a shot of the passenger side, and as you gear jamming guys can see I have hardware where you don't. The two black lines you see next to the lower block, below the exhaust ports are coolant lines for the tiptronic transmission! The forward exhaust port is directly above the the line and directly in the way of the forward exhaust tube. These lines are "T'ed" into the main coolant lines on the forward bulkhead. I tried to move them but the T is rubber and the line is metal. I e-mailed the manufacturer in China and he said " i think we can modify the header for you, but we need you modify the headers first, and then plz send the sample back to me, and we will copy a header for you according to your sample. you only pay the cost of shipping,we will copy the header for you by free.ok?" So they're ready to work with me on the problem.

For the cost I think I'll just see what I have to do to clear the line and e-mail him with the results and have him make me one and pay for it and the shipping. It will be a wash if I had to ship mine back and forth. In the mean time I removed the other header and installed the OEM set so I can drive the car.

I'll keep updates coming when they happen.
