Banks Power Pack / Torque Tyube headers noise
I know in the past, on other vehicles, whenever I switched from manifolds to headers the noise from the engine bay increased in the cab. I would be interested to hear from anyone out there currently ...

Yes they add some noise but it sounds more like air rushing. The muffler adds more exhaust noise. Worth it in my opinion. There are some good sound reduction methods (coatings and insulation) that can help too if it turns out to be much.
