    Guides & Articles

    • Replacement Exhaust Parts
      Exhaust Clamps, Gaskets & Hangers | Don’t Skimp on the Small Stuff!
      Exhaust system gaskets, clamps, and hanger pieces are probably some of the most overlooked parts on your entire vehicle. Since you don't see them, clean them, or maintain them, they're usually out of mind until they become degraded and fail. And degraded they are, because whenever exhaust pipes and mufflers are replaced, these old support pieces are usually always corroded beyond the point of re-using.
    • Performance Exhaust Systems
      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".

Below, we'll take a look at things worth considering to help you make a better choice if you're facing that same question.

In this article, we'll help you understand the differences between these two styles so you can make a more informed purchase.
