I know I'm asking alot of guestions! However two heads are better than one. I have a 428 bored 60 over, Ram Air IV heads, 850 holly. Hooker Headers 2 inch pipes, 3.5 inch flange. Horsepower will be aprox 425 HP. 410 Rear. 5 speed. Question: What size exhaust do I need? I wiil be running them from front to back. Some vendors say 2.5" others 3". I would think the horsepower and cubes dictate what size to use. Correct? As usual getting it right the first time is my biggest concern.
