It only throws the CEL because it's getting the wrong signal, it doesn't care that the actual wiring harness is unplugged...acidbbg said:

Well, the rear gasket hasn't shown up yet. Autozone, Advance Auto, Summit Racing and Napa all don't have one so I I'll probably have to wait for the one from Apex to show up before I put the pipe on. I found one at a local exhaust shop that might fit though, so I'll try and get it all figured out today and post the results. Sorry I didn't get back yesterday, but I got called into work and didn't get home till 1:00 this morning (overtime 
). Thanks for the posts guys

How do you know this? B/c If you think of the ecu like your home computer...and unlplug your house telephone line...Well when the computer tries to access the modem...and it notices that there is no connection..it's going to notify you that something is wrong...Glowmunkey said:
I think the concept is similar...I am a computer science major..and have been studying many different computers..
What do you have to back up what you are saying? Have you done any tests..or just assuming that it would happen?

Just go to your local exhaust shop..like mieneke..i am sure they will have what you are looking for..i had the same problem when i installed my turbo kit..but i went to my exhuast shop..and it's wasn't a problem..he had many in stock..our exhust system..isn't anything special..Mach 3.5 Turbo said:Well, the rear gasket hasn't shown up yet.

Trust me, I am 100% positive. I've done it. The only way the ECU can tell a sensor is unplugged, is when it doesn't recieve the proper input signal. I've hooked up actual signal generators in order to modify how the ECU responds.acidbbg said:
I'm not positive, but I bet you could trick your home computer too, the only way they would know is if they have an actual sensor on the wiring harness plug. I'll bet they can just tell when the signal changes, or disappears entirely (like unplugging the ethernet cable).
So are we all set now? I'm not going to take part in a big debate, I've seen and done this with my own two eyes and hands. I was just hoping for some input... ah well, time for fun with the multi-meter.

Well, my camera is busted or something. It won't turn on 
. I'll see if Best Buy honors the warantee tommorow and post some pics then. I did try it out though, and it worked fine. I put the MIL eliminator on the O2 sensor and screwed it back into the stock downpipe. No CEL. So I drove around for a while. Still no CEL. I went ahead and installed the Apex catless downpipe and screwed the O2 sensor in. Still no CEL. I'll post again if it ever turns on, but it looks like a modified O2 sensor WILL work on a stock downpipe. I don't think the dealership would even notice it's there, and maybe they won't care if they do, but I don't want to risk it. If I ever need to take it back to the dealership, I'll spend a couple of hours switching out the exhaust and intake just to make them happy.
I think if I ever up the boost, or anything else risky, I'll just consider my warrantee null. In the meantime though, I don't feel like I'm cheating the dealer when they're voiding warrantees for rediculous reasons. I think I found the reason they jump all over the warrantee last time I talked to my dealer though. They were trying to become vendors for Injen intakes, and told me that if I got one anywhere else they will consider my warrantee void since they only trust their mechanics. So there it is, it's all about the bottom line. I doubt all dealers are this way, but mine seemed to just want to hold my warrantee randsom unless I paid them inflated prices and extreme service charges to put it on. Boooooo

Well, think about it from their point of view... they don't want to warranty someone else's work. Would YOU do that?Mach 3.5 Turbo said:
there is a special socket called an O2 puller. do yourself a favor and get the right tool for the job.
the way the resistor works is that when the stock setup is working fine and the sensor is happy, it gives a happy signal.
when you get an aftermarket downpipe taht eliminate both cats, the o2 signal is pissed off so it sends a pissed off signal to the computer, causing the check engine light to illuminate.
what this resistor does is that whatever the O2 is saying, it makes it a happy signal so the ECU doesnt know whats goin on. so yes it will work on the stock setup.

I'm not concerned about the warranty on the parts I've installed myself, I don't think they should have anything to do with that. I've heard horror stories about the dealer voiding the entire drivetrain warranty for life just because they spotted a boost gauge in there, and that was enough reason for them to believe the guy increased his boost. I'm not about cheating the dealer, I think they work hard for their money and deserve to be treated fairly. So do we though. If I put a catless downpipe on there, and the water pump fails, I don't want to be blamed for it. If I do screw up something in the car and it breaks, I'm honest enough to not take it to the dealer. If it was truly a manufacturing defect however(clunk, flash, etc), I expect my warranty to be honored. If that means I have to reduce the car to bone stock so they treat me fairly, then I will. I don't think it should be this way, though, and I'm sure most of the dealers out there are fair. I just don't want to risk it since my dealer told me that installing an intake myself will void the drivetrain warranty because I'm so stupid I can't be trusted to put it on right. We treat them fairly and I think we deserve the same in return.Glowmunkey said:

Point well taken. As unfortunate as it is, that could very well be the reality... some dealerships just seem so over-anxious to get people's warranty's voided.Mach 3.5 Turbo said:
