I'd like to get an o/r x-pipe as my next mod. Supposedly, the two brands that I'm interested in (Pypes and JBA) will bolt right up to the factory manifolds. Will any modifications be needed for the front O2 sensors? Do these mid-pipes come with O2 bungs? Are O2 extenders needed? I was told not to be concerned with the rear O2 sensors. These can be turned off by your dyno tuner, or with a handheld tuner, and have nothing to do with engine performance. Thanks for any feedback here.

Just installed the pypes off road x last weekend.Fit like a glove.One tip though make sure the flange on the driver side of the x pipe is loose before tightening the manifold nuts.This will let it move .I was fortunate and my car has not thrown any check engine lights ( knock on wood) yet.I would try it first before you spend money .By the way, 15 mm deepwell socket and a couple entensions before you even begin.I pulled the rear on ramps, and put the front on jackstands.One of the mnifold nuts was a little stubborn, other than that it is a breeze.
