if the dp doesn't have a spot for the o2 i'd just zip tie it up some where and put a cap on the end of it or just take it off the sensor clip i forget how that one is hooked up haven't messed with the dp in forever lol.
need to tune it out too.

Thanks for the input guys! Tune it out? Take it to a shop to do that? Gm dealer?

someone with HPTuners just needs to take the code out gonna cost money though you may just wanna chill with the cel light on till you get some mods

I just installed a ZZP Catless downpipe on my car. If you follow the sensor wires you will find a clip. The clip is hard to see, but it is close to the rack and pinion steering. It can be alittle tricky, but you pull the blue pin out and use a flat tip screw driver to unclip the wire. Then the sensor and the segment of wire attached to the sensor can be removed completely. Hope this helps. Good Luck.

Thanks a lot that will help! Any of you guys with the catless downpipe have it on a ss/sc? And if so how does it sound? I'm pairing mine up with the borla xr1 muffler..wishikn I had a tc right about now but I think ill be alright

will sound like crap prob lol not much you can do on an ss/sc that's why i'd never get a catless dp on one but if it sounds too bad just get a resonator or something

gonzmexican

Thanks..not what I wanted to hear but thanks for the honesty lol, anyone else have any opnion? I really don't want a bad sounding exhaust, should I return the dp and muffler and get the megan racing catback for 299?

ummm well slowline is right, ive had a catless with a gmpp touring exhaust and it sounded very deep on cruising but sounded very high pitched and as deep as a catted dp, I've tried the catless dp with a vibrant resonator and it sounded great i kinda got the same results as having a jbp header " I forgot who's car it's on now lol " I woulda loved to keep it but got in trouble with it " long story lol " but now im runnig a 3" catted dp and sounds as good as stock just a little bit louder and deeper

gonzmexican

Ah that puts me a little more at ease..ill try with this setup and see how I like the tone

gonzmexican

well the borla xr-1 muffler is in and sounds great has a deep tone and a nice rumble to it..going to install the zzp downpipe on friday as well as do the airbox mod..ill try to post some videos this coming weekend of the whole set up
