V-bands will be clamped on pretty good after loosening the 13mm. Use a long extension and tap it loose. With the exhaust, I took off the center support and also the 2 rears rubber support which are colored red held by 1 13mm bolt each. This gave me plenty of room to maneuver the downpipes in/out. As far as the secondary o2, I installed spacers from amazon which were $10 for 2. No CEL yet. I'm also running JB4 so not sure if that eliminates the CEL but according to the new revision, JB4 no longer deletes codes automatically.
