Response to Re: Hooker Aero Chambers?? 2.5" or 3" Pipe?

If it is a truck with a gas tank inboard of the frame put a single exhaust on it. 3 1/2" is fine for the 390 but for a 428 and more RPM use 4". Big truck mufflers are cheap and available with a variety of lengths and decibel dampening. Check the Donaldson catalog. The routing is easier, weighs less than duals and I think it makes more power too. My ramp truck with a 428 and single 4" and my 302 Ranger with single 3" both ran quicker ET trough the whole system and the Ranger even had two 2 1/2" cats before it merged into single.
