Exhaust popping from cold on overrun

[Wellbs]

When stone cold the exhaust pops from the decat on the overrun from about 4k. Is this normal or because i have no silencer in place?

Mine does that with a cat. Although it's probably not nearly as loud.

Mine did too.. i'll be honest i was convinced after being told by a mechanic (not to be named) that it was my silencer disintegrating and so my car is now straight piped lol.
