Could be a leak at the uppipe flanges, or the EGT sender is leaking, or you have a cracked manifold or an uppipe bellow burst, or the Vband at the downpipe isnt connected tightly, or you have a leak at a joint (did you use band clamps?).

As you can see, theres just too many variables for someone who's not there to figure it out.
You need to narrow down where you are hearing the leak from and start inspecting.
