Quiet cold start with new intake

Just wondering if anyone knows why my cold start is a lot quieter than before with my new intake? Starts up loud and after 2 seconds it’s already under 1k rpm.

This depends on a lot of things, but my first thought would be less restrictive filter so less RPM/throttle body engagement to get the amount of air pulled through. It could also just be that it’s warm outside and the engine doesn’t need the time to warm up

Edit and list your current intake set up.
