Exhaust specifications. THIS IS NOT ANOTHER WHICH EXHAUST SOUNDS BETTER THREAD!
I am planning on changing the muffler on my truck. I need to know what size the pipe is before the muffler? I have been told that its three inch until the muffler then comes out of the muffler at 2.5 but I am not for sure. Does anyone know for sure what size it is. I am planning on running a Flow super 44 3inch in 3 inch out single three inch pipe same location as stock. Thanks for the help guys.

You are correct, Your truck has a 3" inlet and 2.5" out, but why do you want a 3" out single pipe? Just being curious.1999 Silverado Regular Cab Short Box

I prefer the 40's over the super 44. I have a super 44 on my Sierra and it has way too much resonance and not enough "bite" to it for taste.2010 Equinox LT
