Wonderful discussion here! My two cents :
I'm a long tube fan. Every truck I've owned, first thing I did was put long tubes and straight duals on. BUT, with my 92, I put on shorty headers. Was a lot of thinking involved. What it came down to was the the trucks make AWESOME low range torque anyway. It's mid and high were they lack. Which shorties are perfect for. Long tubes are great for low range, but don't do mid and high like a shorty. Plus, there's not a whole lot of room under these trucks for exhaust. So with my shorties, I put in a short elbow and a thrush glass pack on each side. End of exhaust. Total of MAYBE 3 feet lol. With long tubes, I'd have to put in a y pipe which I hate. Outcome - AWESOME! The flow was awesome, woke up the engine all the way to 4 grand (I love mud haha) and never lost any power at the low end. I actually gained through the entire band. Then again I also put in a torker2 carb intake and a 454 throttle body with cop injectors on a 305 lol. It loved that combination tho. I was pullin trucks out of creeks when NBS diesels couldn't budge them.
