      Why Do Some Replacement Exhaust Manifolds Come With Catalytic Converters?
      If you're looking for a replacement exhaust manifold, you may notice that the choices available for your specific vehicle are only available with an "integrated" catalytic converter. In the same way, a search for a replacement catalytic converter may only turn up "combination" converter/manifold products.
    • Bed Accessories
      Pickup Truck Cab And Bed Sizes Are Important When Selecting Accessories
      Americans love to have choices. Buying a dress shirt? Decide solid or stripe, short or long sleeve, cotton or poly blend, button or spread collar, regular fit, slim fit, or big & tall. How about a meal at your favorite steak house? Will it be porterhouse, T-bone, or sirloin? Cooked rare, medium-rare, or medium? With baked, mashed, or French fried potatoes? Thirsty for a fancy cup of coffee? Let's not even get started on options that let you end up with a "grande caramel macchiato with 1% low-fat milk, 2 Splendas, and an extra espresso shot".

      Auto Parts: Dealer vs. Aftermarket
      The question of whether to buy parts from an automotive dealer vs. ones from aftermarket manufacturers is as age-old as the automobile itself. Below, we'll take a look at things worth considering to help you make a better choice if you're facing that same question. Automobile manufacturers and dealerships always advertise the fact that their parts are "genuine" because they were made by the exact same production facility that made the parts installed on the assembly line.

      Direct Fit vs. Universal Mufflers
      Regardless of whether you're shopping for a simple replacement muffler that delivers original equipment (OE) sound and performance or an upgraded muffler which provides a deeper growl with increased power through freer exhaust flow, you'll see choices between "direct fit" mufflers and "universal" mufflers. In this article, we'll help you understand the differences between these two styles so you can make a more informed purchase.
