I'm not a mechanic but a couple of suggestions.

Check the bolts in each header pipe that are removed for checking the CO etc. they sometimes fall out.
Check the exhaust system for any other leaks.

Yep and check the seals where the headers join up with the downpipes.Mine were blowing like a very blowy thing.Had two seals replaced at the last service.

ive noticed the exhaust fit seems a little loose on my st2
