newbie looking for boltons

[SandShots]

i have an 05 silverado hd 1500 4x4 with a 6.0- 4.10gears

 

i wanted to know what you guys are doing to your trucks to increase mileage.

im looking for boltons, i know exaust is the way to go but i dont like the cab rumble from loud mufflers, any mild ones out there worth a shot?

Welcome, a lot of guys have gone with tuning for increased performance as well as some mileage improvement.

I have a 2003 Z71 extended cab and I put corsa exhaust from cat back and when your running down the road at speed you don't even know that you have a system on the truck,also I put a k&n air box it picked up some also some hp gain too.
