Jenna and Justin, thank you for the information. I'm very fortunate that being in Washington, I do not have any restrictions for headers. I am very familiar with Doug Thorley headers, and had a set of JBA's several years ago on my Silverado, so I will take a look at the suggestions you listed.
Edit: after checking out all of the options that I could find, I'm really impressed by the Kooks headers. So once I get my brakes done (parts ordered) I hope I can turn attention to getting those picked up. I really like that the Kooks have a long tube header for our trucks.
Now Jenna, my question for you with your background in tuning, would a "true duel" exhaust in 3" be ok with eventual plans for tuning and either internal parts or induction? Or will that be too large, thus causing too much of a drop in back pressure? I know short term it would rob from low end torque just from the physics in back pressure, just not sure on overall performance or if best in long term.
Thank you again.
Joe
