Thanks Bernd.
We installed a Borla cat-back exhaust for a 4.7 a couple days ago. There
doesn't seem to be any bogging. Take off response may be a little better.
Definitely is much louder, inside the cab is unbelievable but outside it's
not bad. We've driven about 100 miles now and it seems to be quieting down a
bit and gas mileage is up.
