Slight hissing on acceleration when cold

I was wondering if this is possibly an exhaust leak? It only happens within the first couple minutes when I start the car. I'm guessing when the pipes warm up

Default Slight hissing on acceleration when cold

I was wondering if this is possibly an exhaust leak? It only happens within the first couple minutes when I start the car. I'm guessing when the pipes warm up they expand slightly and seal the leak? It sounds similar to the hiss on deceleration and I only really hear it under moderately high to high throttle. It seems pretty harmless but just wanted to ask
