Exhaust for sure, make the truck way more fun to drive, and actually feels like you are driving a V8, not a 4 cylinder.

 

I'll go against the grain and say the AS. Even though you want a new exhaust you already have one on there, albeit quiet. I got fuzzy logic (so says the GF) but I did the AS first because it was a "new" addition, the exhaust will come later, for now the factory exhaust will suffice.

 

definitly exhaust. i personally dont like the AS unless your getting bigger tires. A truck should be slightly lower in the front. I have also heard lots of times people saying after their AS or Daystar or whatever their front sits higher than the back and then they go looking for an add a leaf and then its just a big hassle. go with the exhaust.

 

I'd be getting an AS that lifts the truck 2" up front. I think it's a 1 5/8" spacer. And yes I'd be getting bigger tires eventually, 285/70-17's. Whatever I decide I'll be ordering tomorrow. Yeah
