To remove the tranny cover, continue down the drivetrain along the cover. Remove the front two screw bolts (8mm), middle two washer nuts (10mm) and rear two screw bolts (10mm).

Then remove the front driver's side 02 harness connection cover. Two 10 mm bolts. It is a little tight with the skidplate attached in front but hanging loose in the rear, but totally doable with a 1/4 drive ratchet.

Then disconnect the front 02 on each side at the connector. Route the cable out of its holder clips and free of anything that would obstruct lowering the midpipe. Move on to the rear 02. Pull the harness connector down and disconnect it. Make sure the harness ends are free so the midpipe can drop.

Undo the front header to midpipe connectors. If you cannot get a torx fitting in there on top, a flex head 10 mm ratcheting wrench works fine. Work it into position at a right angle. Then use a 14 or 15 mm (forget which) ratchet or impact on the nut end. Undo each pair.

Undo the front flexi arm supports. 13 mm.

Move down to the far end of the midpipe and undo the mid to rerar exhaust clamps. Slide them back.

No go to the middle cross brace. Remove one 13 mm bolt each side. When you are ready to support the midpipe and let it drop, undo the remaining bolt each side.

If the midpipe does not drop, push the rear exhaust back to free up that end and wiggle the front end. It will come down. Be prepared since it weighs about 40 lbs.

Follow these directions and you cant screw up!
