I have a set of the str chania headers and a terry houston 3" downpipe. and a standard test pipe in place of the cat. I don't have a drone. it's raspy under WOT but normal drivng it doesn't seem to have a drone.
But i do have a stroker engine so maybe that has changed it i dunno?
The ATR 3" cross flow is not a real cross flow. It only has ONE inlet pipe and a dual outlets. Check out Bob's system and you'll see what I mean. A true dual cross flow system completely eliminates drone. Nothing else comes even a close second besides a completely stock system with cat.
