Brand New Sierra 2wd 4.8L, A4, 3.73 locker
What should my first mod be? I am thinking of replacing the stock muffler with a 5" round 3" I/O Borla muffler. How will it sound with stock manifolds and cats?
After thet you should get some E-fans, UD pulley, Stall, nice cam... and some spray.

If you go with the muffler first it should sound pretty good with the stock mani's and cats. I think it'll give a mid-tone sound.
I would go with a tune first. That'll wake the 4.8 up. Nelson for sure, right top corner.

How much power do the e-fans add?
Should I get an entire catback or will changing the muffler be enough?
For the stall I was thinking of the PI 2800 with number zero pump. And maybe some 4.56 gears with Lightning size Nittos on 18" rims. Drop it 2/4
