No, they are out for HP. I'm not today.
Your beloved Mandrel Bends and other components are great for running at or near WOT. I'm not planning on being there.
Alright, try this on. Go to your kitchen and get a straw. Suck some water out of a glass.
Now put a little bit of bend in it. Try again. its probably not that much more difficult but you are only talking a few grams of water over a very short distance. Lets multiply that by say 2 feet same diamter piping and its roughly equivalent to the exhaust in the pipes.
If you still disagree go down to your local fire department lay some hose out and ask them to cut it on. I promise you all but the last few feet of that hose will be in a straight line from the pump in an instant and anyone in the way will have serious friction burns(its happened to me).
Now the gains to be had from making a fire house straight are obviously greater than my exhaust because water is much more dense. That said there are still obviously gains.
