CEL on

Twice in the past 2 weeks since i got my hard pipe and BOV on, my CEL has come on.
The code is 0455. Exhaust evaporative system leak (large).
The car drives normally, builds boost fine, pulls fine, and the code once erased stayed off for a long time. Then it came back on today, and i erased it again.
Has anyone else had this code come on, or have any insight?
I know the exhaust evaporative is really a fuel vapor system leak. Im worried its a possible fuel tank problem.
I guess if it comes back on it goes to the dealer to be checked.

Let me know if anyone else has had this problem
Thanks
