Hello all. New guy here I recently purchased a new 2010 chevy silverado. it has the 4.8 v8 2wd. and i looove the power, coming from a 4.3. that being said, i'd like MORE. lol isn't that always the case? needing more power. Anyway, i DID just buy a new truck and i don't have a lotta money to spend, so i'm thinking an intake and muffler would be the obvious choice. So, realistically, what kind of horsepower gains should i expect from...say, a K&N air intake system, and a flow master muffler, or corsa, Single in-Dual out. Sorry if this could've been found using the search feature. i DID look, but it's late, and i'm late for bed. Thanks for any input!
