Can someone tell me why? (4.2 exhaust)

Why would driver side pipe flow way more than passenger? I can bearably feel exhaust gases out of the passenger side and looks like 4.2 came stock with x pipe so it cant be cats

There's just a small hole in that x
Its for a nicer exhaust tone
most of the pressure should pop through the straight pipe

The problem could be that one of your mufflers is deteriorating and is partially clogged so the flow for that side is flowing through the X pipe to the other side.
