[QUOTE="SilverGT1, post: 16381419, member: 186800"] 2003 GT Kenne Bell 2.1 Magnaflow 441114 I am getting ready to install an Innovate PSB-1 AFR meter. I just installed a new CARB approved Magnaflow 4-Cat exhaust (because of the crushing smog inspecting here in California). This is replacing my Magnaflow 2-Cat x-pipe. With the Magnaflow 4-Cat system, they have included three bungs on each side. One before the pre-cat, one between the pre-cat and the downstream cat, and one after the downstream cat. Here is my issue; on the Magnaflow exhaust, the way they welded the pre-cat in, there no way to add another accessible bung for the wideband sensor. Option 1? Can I use that pre-installed bung that is between the pre-cat and downstream cat for the wideband or will I get erroneous AFR / Lambda measurements? Option 2? After I get the car smogged, can I swap the pre-cat O2 sensor to the middle position just before the downstream cat and then put my wideband in the pre-cat location? I don't know if this is going to cause the O2 to throw codes. Options 3) Weld in a new bung after the downstream cat. Thoughts? [ATTACH=full]1628247[/ATTACH] [ATTACH=full]1628248[/ATTACH] [/QUOTE]
