Hey guys im looking to buy a 99 sierra extended cab with a 5.3. Im a big GM fan so I know some of the things that go wrong like the cab corners and rocker pannels. But a guy at work told me the other day to check for the bed rails under the bed because they tend to rust. Has anybody had a problem like that? And another question is when I buy the truck I plan on putting a exhaust on it but im not sure which one to put on it. Im leaning towards Flowmaster super 10 series. Let me know what you think I should do and problems with these trucks.
