Will an X pipe make me run too rich?

[VatStang]

I currently have a decent amount of mods. Still to lazy to get a tune. One of my friends who knows a bunch on the 4.6 says I'm probably too lean right now, and an o/r would make it a hellova lot leaner. Any guys with a similar combo to me not have any problems? If I do get the midpipe, are the mil's absolutly neccessary? I also don't want a popping sound that I hear some x pipes give you; would an H not give me that? I am really not all that concerned about power because the h and the x are probably within 5 hp of one another. What do you guys think?

Looks like you have an ample set of intake mods, opening up the exhaust side would certainly equal things out and work together well with the intake portion.

I say a mid pipe and catback is long over due for the amount of work you have done to the intake.

IF you get a midpipe with cats, then no, nothing is required. If you get an off-road, then you gotta get MIL's or a chip.
