Today I installed a new trubendz y-pipe and high flow cat. After install I now get a cabin vibration at idle. I checked the exhaust to see if it was touching anywhere, but did not see anything. Is it perhaps due to the high flow cat?
Check your entire exhaust for contact with the body. I had it happen once when the rear-most hanger caught on the rear tow hook.

do u have the flex pipe or the ball joint connection for the Y-pipe to cat pipe? could be due to over tightening because these are designed to absorb vibrations so it doesnt go down the whole exhaust pipe

The Y-pipe and cat is one piece with a flex pipe before the cat.
I'll take another look and see if anything is touching the body

Well I found the problem. The factory mounting bracket for the y-pipe, on the oil pan is cracked and waas bending up, causing the y-pipes bracket to touch the right axle shaft support bracket.
I just took the broken factory bracket off and bent the y-pipe bracket a little to make sure it didn't touch on the axle shaft bracket.
Nice and smooth now, no cabin vibration!
