Had a dual exhaust system on my dodge 360v8 it sounded great. Combined with a standard transmission it was really nice to hear it rumble or really sing if I was getting on it. The fun ended after about half an hour of pulling my fifth wheel down the highway. Mine were cut out the side between the rear tire and bumper. If I could go back and do it all over again the only thing I would change is to put 4.10 or 4.30 rear in it so it would pull a little better. Do it, you only live once and you can always put it back if you wan to.
