Hi guys. Am new here but not new to modifying engines. Am in the market for a silverado. Seems that most of them have the 5.3 engine in them. I would prefer a 6.2 but will take what I can get.

Questions are: Which mods give the most bang for the buck? I have to drive this to work every day. I understand installing a cold air kit, tuner and exhaust. Will these mods make a difference you can feel? I am at the age now where I dont want to be doing a camshaft swap so advice on the most simple of bolts ons is appreciated.

Exhaust is important. Dont want to be waking up the neighbors at 4 in the morning but a nice rumble is what I am after.

Thanks
