Hi all, new to the site and actually just bought my first truck a month ago. It's a dark blue 2006 Silverado LS with a 4.8L V8 and 59k miles, extended cab, short bed, 2wd. I love the look of chrome on dark vehicles so I have installed chrome door handle covers, mirror covers, tailgate handle cover, fuel door cover, bug deflector, and a cab brake light cover. There are still a few things I would like to add to the truck. 1. Chrome tail light bezels/covers 2. Either chrome fender trim Or chrome rocker panel molding (I would remove the stock black plastic molding if I went with the rocker panel molding) looking for input here 3. Exhaust, or maybe just a muffler. I really just want it to sound mean. Looking for advice as to which option and what muffler sounds best 4. Tires and rims, I was thinking about 20" (6 lug) chrome rims with some meaty tires. I don't know the biggest size tire I can fit without lifting the truck, but I would like something about 34" 5. Nerf bars 6. Suggestions on how to improve gas mileage (I am only getting 17mpg on the highway) I am from the Toledo area, but will be in New Mexico, Cincinnati, Charleston (SC), and Minneapolis over the next four months. If anyone knows of places I can get good deals on the above items or has any other suggestions I am all ears.
