Engine Masters dyno tested an engine with mandrel bent and "crunch" bent pipe. Don't recall the engine or CID, but I've not seen Freiburger, Dulcich, and Brule do less than 450hp. As I recall, their testing showed virtually no difference in the torque and hp curves.
Their video's on YouTube but I couldn't get the link to work w/o signing up for Max, which I did not do, so I could verify the engine and test results. When I tried to copy/paste it here it was blocked. Maybe you can watch it. Search "Mandrel- v. Crunch-Bent Exhaust".
