Slip on exhaust leak?

I recently installed a Tab Performance slip on (redline baffles) on my 2026 LowRider ST. I watched their installation video as well as a few more on YouTube. I have the mounting screws perfectly aligned and the exhaust clamp in about 1/4 way back on the muffler from the front. I have everything torqued to spec. However… if I stick my hand slightly in front of the connection by the catalytic converter I can feel a tiny “puff” of air as the bike idles.

Is this normal or do I not have the connection correct and have now created an exhaust leak?

I checked around the clamp and where the slip on is attached and it is as far forward as possible.
