I ran LT's with a section of pipe that would run the exhaust out from under the car in about the middle of the doors. As Grn92LX said it sounds pretty bad. For sheer volume I don't know if you can beat it but for a good sound it's not the way to go. I never got pulled over with them and ran them that way for about 2-3 months but that depends on where you live and how the cops are.
