      Here's A 'Tip': Exhaust Tips Are An Easy Way To Dress Up Your Tailpipe
      Performance exhaust systems give you improvements in power output, sound levels, and appearance, all in one package. But let's face it: not everyone has the spare change to buy and bolt up one of these kits. So you soldier on with what you have. And that may be a tired-looking exhaust system that is still functional. You've spent all day washing and waxing the vehicle's paint and chrome to perfection, but no degree of elbow grease will make that tailpipe look better.

      Are Headers Worth The Performance Improvement?
      Engines have often been compared to air pumps, because the engine that’s most efficient in terms of economy and power is the one that can get air in and out of its cylinders the easiest. That’s why most performance modifications like conical air filters, cold air intake systems, headers, and cat-back exhaust systems are aimed at making the intake and exhaust systems less restrictive. These parts increase the flow of air into the engine and ease the flow of exhaust gas out of the engine. Among these components, headers may be the most difficult to install. In this article, we’ll discuss what headers do, their different types, and how much performance they can add to your car.

      Are X-pipes and H-pipes Better Than Straight Pipes on Dual Exhaust Systems?
      You may be wondering why so many aftermarket performance exhaust system manufacturers are offering dual exhaust systems connected by "H-pipe" or "X-pipe" sections. After all, aren't two separate pipes, or so-called "true duals", the best for performance? The answer is no, but to understand why we have to examine how a typical internal combustion engine works.

      Power, Sound, Looks | Can I Have It All With a Cat-Back Exhaust System?
      It's an age-old question that many have asked. Will an aftermarket exhaust be worth the expense? While they definitely can be, an important question to ask yourself is do you care more about the deeper sound they’re designed to produce, or the added performance gained from being less restrictive? As car enthusiasts, we’ve become accustomed to associating the sound of a car with its exhaust. After all, doesn’t everyone have a childhood memory or two of a car and the particular sound it made?

      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?

      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.

    BORLA Cat-Back for FX 50S
    I Love this performance exhaust! It is exactly what I was looking for in both performance and sound. At start-up there is a very nice growl that subsides to a low rumble, but doesn't impinge on the occupants of the vehicle. At normal cruising speeds, there is Zero drone! I can tell that there is more throatiness while driving but it is very slight. However, when I put the juice to it, the sound coming out is a symphony! What I desired and what Borla has achieved is that unless I am hammering the accelerator no one knows that I have a Beast of a car. It is fantastic. Now to some real world numbers. I have not placed the car on a dyno yet, but will be in the next few weeks. I have put over 1,000 miles on the car with the new exhaust. I also installed new K&N filters so I am not sure how to attribute percentages to just the BORLA exhaust, but take these numbers for what they are...data. Again, I don't have HP increases yet, but I do have performance numbers. My MPG has increased dramatically. I am now getting 1.8 MPG in city driving and I have gained 3.3 MPG on highway driving. To show the numbers here they are before and after: 16.2 MPG before and 18 after, which is an 11% gain for city driving. 20.2 MPG before and 23.5 after, which is a 16.3% gain for highway driving. I am not a professional driver by any means, but I was able to shave .3 seconds off of my best time in 0-60 after install if the new filters and BORLA exhaust. I can also tell that the car is much more peppy. It has increased throttle response and is so ready to run when I give it the juice. All around I am so very happy with the BORLA exhaust. It has unleashed an already fast car and made it sound like a race-car!
