jrhgolf23 Posted October 25, 2011 Report Share Posted October 25, 2011 Soo I now have a *DM downpipe but the stock o2 sensor. There is that bracket on the stock o2 so you can mount it to the cat, but I need to screw the o2 into my downpipe.. Is there any way to get that bracket off? And if so, is there any trick to doing it? Cus I can't get it. LolThanks for any help. Link to comment Share on other sites More sharing options...
Dan87quest Posted October 25, 2011 Report Share Posted October 25, 2011 Just get a 1 wire o2 sensor go to the part store and have them look a universal 1 wire. Splice it in and your ready to go. Link to comment Share on other sites More sharing options...
DarksideDSM Posted October 25, 2011 Report Share Posted October 25, 2011 Dan is right. You can source a weld in bung easily and put a 1 wire universal there if theres no hole for it already. If there is all you need is an o2 and your good. splice the wire into the stock o2's plug and plug it in. Link to comment Share on other sites More sharing options...
Indiana Posted October 25, 2011 Report Share Posted October 25, 2011 (edited) At minimum get at least a three wire 02 so you'll have it heated if there is, and there usually is, issues with it not getting hot enough.

jrhgolf23 Posted October 25, 2011 Author Report Share Posted October 25, 2011 There is already the bung in the dp, but my o2 wont screw into it because of the bracket on my o2. I guess I didnt realize there are universal o2 sensors. Thanks guys Link to comment Share on other sites More sharing options...
Leeintheconquest Posted October 25, 2011 Report Share Posted October 25, 2011 You can get the screw in type sensor with the factory one wire clip as well. A couple bucks more.....but if you don't want to splice it's an option. If yo splice it.....solder it. Link to comment Share on other sites More sharing options...
DarksideDSM Posted October 26, 2011 Report Share Posted October 26, 2011 Yes solder is the best bet. and yes there are universal o2's and a lot of newer vehicles use them. They are about $20. 3 wire is better also although they are about twice as much. It has a heating element that gets it to and keeps it at optimal temperature for accurate readings. The 1 wire requires the exhaust keep it hot enough and the heat is what gives it the power to give a reading, so if its cold or extra hot it will read off a little.

Tim_C. Posted October 26, 2011 Report Share Posted October 26, 2011 Never put a one wire O2 on an open downpipe. Go 3 wire or park it and save your money until you can go 3 wire. Link to comment Share on other sites More sharing options...

Thanks guys UNSCREW IT FROM THE MOUNTING PLATE, if you bought the correct one.Three wire O-2 Sensors are the way to go. Heats up to give you a faster reading to the sensors and thus, the ECU. Now, your car with the 1 Wire O-2 takes a long time to heat up enough so the sensors and the ECU can deduct that it is at operating temps. You won't have that problem with the Three-Wire. Does your car run super rich at start up when it is cold? Most do. With a Three-Wire O-2 Sensor your Idle will lean out faster.
