Default weird exhaust pressure

Okay so my car putters at idle and is sluggish in first. it has 61k, intake test pipe hks hi power exhaust

The driver side exhaust pushes the paper i put in front of it out and during the quick sputter is goes in, while the passenger is pretty much suckin in the paper the entire time.

Thoughts and suggestions more than welcome of course. Please throw anything my way. Or if its normal, then just call me a dummy. TIA.

I expect it's normal.

At idle the passenger side exhaust is exhibiting venturi effect. the air rushing through the exhaust to the drivers side is drawing in air through the passenger side.

At WOT the situation would be very different.

So, at idle, there is no need for a dual exhaust .
