Looking to get some exaust work done on the truck, and I can't seem to find which inlet diameter I need for th enew muffler... I guessing and hoping its a 3" pipe. Am I correct? Thanks guys.
Dang these trucks are choked up. It must be 2.5" then, Im sure it will apprecaite the ability to breathe a little better even it just a dual outlet muffler...

You would be surprised. A truck doesn't need a big pipe. 2.25 is about perfect. It's everything else that hurts the flow; cats, mufflers, etc. You want scavenging and the best way to get this is to the correct sized pipe all the way through.
Yeah, cast iron maniflods+ 2 cats+ single pipe doesnt help the ole 351 breathe easy higher in the power band. Those cats are really going to take a lot of volume out of the exhaust note...
