Disable the rear 02 DTC's and you won't get a light anymore.

 

you'll love it...thats what I am running. I have the corsa going in on thursday...

 

would it be a waist of money if i get the header/dp combo when i want to go turbo but i dont know when i'll have the money for hahn t/kit...or should i just get the dowpipe by it self

 

just save your money....wait

 

Would the code still come up if you scanned the car?

 

thanks...downpipe/headers are so tempted b/c i want the extra 15-20hp gain...but i also want to go turbo as well..i'll try to wait

 

an FYI for the rear O2 sensor....here are the changes that need to be made.

 

Whats causing the code? is it because the exhaust is not being catalyst and emiting more chemicals/pollution into the air?

 

um, no...the lack of an eletrical signal.

 

Ah! i was just checking out this zzp DP! I looking to put it on as well. I have all stock exhaust though plus mods in my sig. Will it make a difference for my application? Change the sound maybe ? Im going to get the one with the HF cat/extra bung (Incase i need it down the road)

 

yes, to all

 

i wish there was a sound clip of the dp on a stock exhaust.

 

you wont be disappointed....change that and the muffler and you'll love the sound and performance..

 

Yea im not to sure what muffler to get. I want it to be a TAD louder then stock. I heard a sound clip for a magnaflow muffler on here, and it was to loud for my taste. It very easy to make these cars sound like rice rockets and thats not what im going for.

 

I hear you, I just got the Corsa cat-back installed. Its actually quieter than the GMPP....it is bigger.

 

Really.... interesting, form the sound clips i have heard it sounded louder, with more pops. I was thinking about just going gm cat-back, but getting the touring one since its almost stock sounding, but still is free flowing with proven gains. But i have yet to hear one in person, i have heard the gmpp and its not to, to bad. But with future mods to the exhaust, it would most likley get a alot louder.

 

Its not as loud....although it is brand new and needs to get coated with the carbon build-up.

 

ah i see, it looks like a very nice system, very good quality. Money well spent. Im definitly going to get the dp, then i can build around it. then later, down the raod i Can decide what im going to do from the cat-->back. But that restictive factory muffler needs to go sooner or later.

 

and what causes the lack of an electrical signal just by using the downpipe? - assuming you are still using the O2 sensor for the PCM and not a wideband one in its place.

 

nothing, you shouldn't get an error...

there is more to it, but its simple, if you change the cat, it might let more heat by, that in turn affects the sensor which makes a different signal.

 

so it is the heat that trips it? if its free flowing wouldnt it cool better?

 

whatever it is, it triggers an electrical impulse, that changes...make sense..?

 

does anyone have a before and after sound clip of their car with the header DP combo? i think i'm going that road very soon.

 

I'm thinking I'm going to go with this downpipe for my ride.

 

is this right? because mine just went off after having it on for like a year or so because i got it put on the same time i had stage 2 put on???????
