Long tubes with cat y-pipe.... ...which, if any, LT's have bungs for the rear O2's? I want to run cats, and I also want the rear O2's for ATaping and tuning with MAFT. FLP's don't have the rear 02 bungs - I'd prefer to buy a set with these already installed.

Re: Long tubes with cat y-pipe.... All long tubes only have the front bung, if any. The rear bung is in the y-pipe behind the cats. That's what you need to be looking for. My Grot setup as well as many others are done this way.

Re: Long tubes with cat y-pipe.... Oops my bad...I put the reference to the y-pipe in the title but wasn't clear in the message. Yep it's the O2's behind the cats the FLP y-pipe is missing. So I need to know which company which offers the cat y-pipe also have the rear 02 bungs?

Re: Long tubes with cat y-pipe.... OK...momentary brainfart question *L*...which 02 sensor is the important one for monitoring with ATAP for A/F ratio purposes - the ones in front of or behind the cats?
