Exhaust theory: Effect of muffler + Cats on Exhaust Pulse???
As for my 2.8's exhaust, I get very little exhaust pulse by the time it reaches the tail pipe; thus, I believe that the cats and mufflers significantly slow and restrict the pulses such that they dissipate completely when they collide with one another when they encounter an obstruction (like the cats or the muffler).
Theoretically, the vacuum left by one exhaust pulse should help pull the following exhaust pulse through the pipe and so on like one domino helping the next.
Any one up on their exhaust theory???
