Extractor Exhaust - what does that mean
Can sombody explain what they mean by "extractor" exhaust?
I understand that the pipes are twisted around to match up #1 & 3 & #4 & 2 cylinders but what does that all mean & why is that better than stock. Why didn't the factory do it that way?
I had an extractor setup on a VW bug, many years ago & it seemed to add power but that could have just been in my head after noticing the improved sound.
My assumption has been that the Bursch setup reduces back pressure & that is why there "may" be inproved power but if anyone has more info - I'd really appreciate it...............Vern
