Maybe I was the only one wondering this... but maybe not. I installed a 40 series DeltaFlow Flowmaster on my 1/2 ton last night. I was kinda a test before ordering the American Thunder system for my 68 Camaro. Anyway, my friend has a 40 series on his Dodge and the resonance is terrible! My DeltaFlow has no resonance at all. I even had to drive to work this morning with the tailpipes unhooked (muffler shop had to make some adjustments) and although they were REALLY LOUD, they still didn't resonate.
God I can't wait to get these on my Camaro!!!
