My brother has 2'' tri-y's with a 3'' x pipe and 3'' straight through mufflers. He has run 10.7 @ 125.5 on pump fuel with a std stroke 440 @ 3650-3700lbs. His car runs like a pig with the pipes disconected. I also have another friend with a 440 with tri-y's and its the same.
I had a 440 with 4 into 1 pipes and it responded well to open pipes. Rob.
