Idle Hang with new Axel Back

[vernonator]

Just had an axle back put on my '16 GTw/PP (Flowmaster Series 40's). Custom shop welded install. I have now noticed that when I clutch-in that the rpm's will hang until I tap the brakes, then it drops to normal idle. Is this just the car learning the new layout and will clear up or is it something to look at? Have less than 150mi on it since the new cans....

Nothing in the exhaust post catalytic converter will effect how the vehicle runs. What you are experiencing is caused by something else or you are just noticing it after the exhaust work.

I am wondering if I am just noticing it because the exhaust note is a bit more noticeable will see if it mellows out as I put more miles on it.
