Ok, quick question for those of you with the UPR CAI.
On the inside of your CAI, right at the bend, is there a rough surface? Mine had it and I thought it was a manufacturing defect, so I sanded it off. Problem is I'm getting a hesitation around 5500 rpm now.
I was thinking it may be there in purpose to slow down the air velocity hitting the wall at the bend and help even out airflow.
Anyone else have this rough patch in there CAI too?
