Kill the back pressure myth
Too bad Big Daddy"Don Garlits" didnt know about back pressure! All those championships he won with open pipes kind of makes you think.
I tune 2 stroke engines where back pressure is needed!
A 4 stroke engine hates back pressure!
Please someone in here with tech knowlage back me up and finally put this f****g
back pressure issue to rest.

Just wanted to add for those who can understand to benifit from back pressure 2 or 4 stroke you need a finely tuned expansion chamber independant for each cylinder to get any gain in power you ever seen a 4 in 1 -2 stroke exhaust?
any gains from backpressure come from a timed pulse wave bounced "back" into "a" cylinder not by chokeing off an entire bank of cylinders.
