who makes headers for 4x4 5.3?

also what exhaust kits sound the best in your opinions ?

anyone have sound clips?

thanks all!

dont know bout tha headers but the aft/cat magnaflow system sounds great..

I have to agree there. I have the Magnaflow catback on my truck and it's really cool. It's not a loud racey sound. At idle it just purrs nice and low. When you hit it at WOT, it really growls to let you know it's there. It also has a nice relaxing drone at about 70mph that will help put the family to sleep on a long ride. :thumb:

Arizona Speed and Marine headers, I had them in my 2WD, sold the truck and change them to my 4WD and they fit perfect.

Magnaflow and Borla would be a choice for mufflers.
