Want to improve the performance of your Oldsmobile Firenza? Consider fitting it with a brand new performance exhaust system from CARiD. Oldsmobile customs exhaust systems are built to pull exhaust gases away from the engine, in this way eliminating the hindrance that prevents the engine from generating as much power as it is capable of. The stock exhaust restricts exhaust flow, only allowing a small amount of exhaust gases to make its way out of the engine at any given time. Spent gases stagnate within the engine, inhibiting the flow of fresh air and fuel needed for the generation of power. This lowers total power output. Replacing your stock exhaust system with a custom built one will eliminate this problem and push the engine to produce the maximum power possible.

There is plenty to choose from and you cannot go wrong with any of our brands because we only deal with the best the industry has to offer. From Borla to MagnaFlow, Flowmaster, Injen and Gibson, we have the power exhausts that will boost your horsepower by 10% or more. You can add an extra 40hp by combining the exhaust system with a performance header from the wide range available. Oldsmobile custom exhaust headers are specially engineered to boost exhaust scavenging and enhance the engine’s ability to breathe. Along with the power increase comes an increase in torque, which will allow you to enjoy greater towing power from your Oldsmobile Firenza. There is also better fuel economy, thanks to the engine’s increased ability to burn fuel more efficiently. Because of its proven endurance and reliability, a custom Oldsmobile Firenza exhaust system will save you lots of money in the long run.

      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? 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".

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