I was pretty sure a lot of longtubes didnt come with any bungs for the 02 sensors? I just bought the Pacesetters, which have them, and was wondering if you guys were plugging them up? Maybe I am just mistaken that some didnt come with the O2 bungs. I am running an offroad Y. Someone refresh my memory with the O2 sensors up front. Thanks guys. -Matt

 

You'll want to have 02's up front. Long Tubes you'll need extension harnesses. Rear 02's with Off-Road pipe you can use 02 Simms. The only plugging on Headers may be the AIR fittings up top one on each side that you might be thinking of.

 

Yeah your right. Thanks man.
