Joe, I truly am running straight pipes on my beefed up 350. Man does it count them off. I can go to a show or cruise and everyone loves it. A couple guys in the club have actually CUT OFF THEIR MUFFLERS saying they love the way it sounds. I also truly have a set of Smitty's that I ordered from Custom Supply out of Florida. I just can't bring myself to put them on. You were right to about how you exit the pipes. I had a set on a 78 once that turned out behind tires like original and I couldn't stay in the truck with glasspaks. Ran them Straight out the back and it wasn't so bad. I may never put mufflers on my 37
