Question Exhaust leak? problem ?

I removed my resonator around 4 months ago, recently I noticed a sound like "thump thump thummp" sound when the car is warming up. But when the car is warm, the sound is gone.
Could it be I have an exhaust leak ? if so, will it cause problems ?

The Komps make a funny noise for about 30-60 seconds when warming up,
till some valve opens.
Also check to see if it's in contact with the shield around the muffler.
