hey im looking at bbk offroad midpipes for LT's. Im leaning towards a XPIPE first does it come with the o2 bungs and hook up for the air pump. Second i will have 1 5/8ths bbk lt's and a SLP LM1 catback will i have a problem with back pressure. Its 2.5" piping all the way out
Unless you have a high RPM 400+ ci stroker, you probably won't have issues with back pressure. You'll need O2 harness extensions to be able to plug in the O2 sensors. You don't need the air pump tube (or assembly for that matter) if you aren't planning on running cats, so if the midpipe has one, you should probably plug it anyway.

Back pressure shouldn't be an issue at all...you really shouldn't have any problems like that unless you're running open headers or something like that. As for the O2 bungs, most long tubes have them but you may have to lengthen the wires to reach them. Also as for the air pump tubes, since they're "off road" they assume you're not running an emissions pump so i've never seen one labeled off road that had one.
Actually come to think of it, my Mac Pro Chamber did in fact have one, but i cut it and welded it shut. Your best bet is to check into it before you buy.
My friend has this identicle set up... BBK LTs, BBK O/R X, and SLP mufflers, only dumped. He has no backpressure issues. Im not sure other than the 02 bungs should be on the headers, and the smog pipe hook up could just be capped off.
well right now i still have the smog hooked up.. although i know i will not pass inspection the cops around here like to do a visual inspection under the hood alot of stolen engines so right now i will be keeping my smog hooked up until i delete it
