has anyone noticed a difference in noise do to weather. In cold (32*) weather the exhaust has a lot more pops to it. In warm weather, the pops aren't there as much. Just wondering is it was a Flowmaster thing or is like that on all trucks.

 

Mine definitely sounds better in colder weather.

 

Haven't noticed a difference.

I have heard that in any vehicle if you have popping/farting on letting off the "go pedal" then usually there is a pin-hole or some sort of leak in the exhaust system between the exhaust manifold and your rear muffler that is letting oxygen into the exhaust to ignite unburned fuel in the piping... hence the popping/farting.

Well... that's what I heard.
