Here are pics of the before and after wrapping the flex joints. The first two pics, I only took a shot of one of the joints because I wasn't really focusing on getting both, but more at the runner part. I thought the two runners on the right were rubbing each other to make that ticking noise but not the case.
Note that there's some yellowish part on the flex. I used black exhaust wrapping. If I used the white wrap that came with the kit, but I already wrapped over the down pipe, I can probably see black carbon on the leaked area more easily.
Since I am not sure which of the two flex joints are leaking, I probably have to remove one of the wraps of the two to determine which one is the culprit. Hoping that both aren't bad.
