Your exhaust should be fine..Torquewar (Andy) runs the same as I do and his exhaust doesn't seem to pose a restriction.He has full 3 inch.My tailpipes were only 2.5 inches and even though they were mandrel bent did cause a restriction.On the other hand it is a cheap test to do!
Do you have flow sheets for your heads?
