question for a friend
well my friend has a 2000 with the 3400 and hes got this great idea for a custom exhaust setup and for this he wont be able to plug in the rear 02 sensor(the one after the cat)will this be a problem cause hes getting a programmer and he can delete the code that it is going to set off, will it be a problem if he doesnt have the code removed right away??

The rear O2 sensor does not affect the car's performance AT ALL. It will just trip the P0420 code and because of that possibly fail inspection. All the rear O2 does it make sure the Cat is working properly. The front O2 sensor could mess with your tune

Why wouldn't he be able to plug in the rear O2? IMO, if he kept a normal cat on there, then I'd prefer to leave the rear O2 in so you know if something goes wrong with it.
Obviously it would be different if he did a cat delete or a high flow cat that didn't meet the OEM specs.
What programmer is he getting? Not every programmer allows you to disable reporting of the codes- the cheap ones can usually only reset codes (which would mean it would still fail emissions).

hes getting some cat and ubend delete downpipe and i dont know what kind of programmer hes getting.
anyway he works at an exhaust shop so he can have a little leway on stuff, but we dont have emision tests around here.

Better have him check and make sure his programmer will do it then, or post up here and we can tell you. No sense in buying a tuner, and still having to send your pcm in for someone else to turn off the code.

zzperformance downpipe, and i was wrong about the tuner, hes got a new pcm sorry. but anyway were working on the car right now and hoping we could get some help real quick, its about 7pm central time here, but could someone help us, we're having some trouble getting the bolts loose off the flanges because they are rusted to hell so what do we do here???????? just so you know its the 3400. also what do these bolts consist of? are they welded onto the flanges with a nut to keep it on or what> like i said there rusted so we cant really tell
