Default Replacing front O2 sensors

How the heck do you do it? Do I need to drop the exhaust? There is no room to replace the pass side, I can maybe do the drivers side....

Unless you have some type of welded aftermarket exhaust, the mid pipe should just unbolt from the manifolds, then off the cat back. Just make sure to unclip all the o2 censors before dropping it out, they have a plug up the wire a little bit, that's probably the hardest part getting them uncliped.

You might can do it with the mid pipe installed, but it shouldn't take very long to drop the mid pipe, change them, and bolt it back up.
