hello

I have a 2007 silverado NBS crew cab with a small 4.8l in it, I tow my camper and was wondering what exhaust and air intake would work the best for torque and would work well with my edge evolution programmer, and if you guys have any other suggestions to create a bit more torque

 

A quickshift kit will help you get going easier by not losing momentum
Shifting between 1st and second gears (if you have an automatic transmission)

A volant or airaid cold air intake with k&n or spectre filter is what I prefer
For a cold air intake

And as far as exhaust... You are gonna get plenty of different opinions,
But I like flowmaster 30 or 40 series. They have chevron shapes inside
The muffler and when the exhaust flows past the chevrons it actually
Creates a vacuum affect and pulls the exhaust out making
The engine work easier and giving you more power to spare.
Nice throaty and deep sounding bit still with a defined sound and not raspy

Good luck!

 

would a dual or single tuned exhaust better for torque

 

a true dual would be the best or tq and single or hp also with the true dual add a x-pipe for even better vacum affect and dont go crazy big in pipe size the right size with a tru dual setup would give the best tq

 

A true dual (2 pipes in 2 pipes out) would be more useful.
A dual will give you more mid-range power whilst a single will give
You more top end power. But I'd rather have more low end power
Any day of the week.
