i installed pacesetter long tubes and i bought two 02 simulators. my question is, how do i install the 02 sims? im running a 2.5" xpipe. will i need 02 bungs welded in? sry im kinda confused on where to put the 02 sims.

 

You'll install two pre-cat 02 bungs (towards engine) on the inside right before the collector flanges, you'll need a couple 02 extensions, these two 02 sensors will control your fuel settings to the pcm when the car is running.

The after cat 02 sensors will go away, you'll need two 02 SIMMs which replicate the after cat fuel settings to the pcm.

oh yeah, I'd recommend installing a couple 02 bungs with threaded plugs on the outside (opposing side of your pre-cat 02 sensor fittings) for future tuning at a shop on a dyno.

 

i already have the front 02's in with the extensions. the headers came with 02 bungs already.

i just need to knwo what all i need for the rear, the after cat 02's. can i just plugin the 02 simulators in the back and call it good?

 

my bad dude, yes just plug them in, thats it, the 02 simms replicate a false signal and thats it.

 

no problem, i wasen't clear enough on my first post. thanks for your help.
