Flowmaster 40 Series Mufflers
Looking for the most aggressive sound in the Flowmaster muffler line? Then take a look at their 40 Series mufflers. Designed for use on street and strip vehicles, they take the sound waves produced in the exhaust, and cancel them against angled baffles built into the muffler case. This improves both horsepower and fuel economy. Best of all, they allow you to hear that cool Flowmaster tone inside of the vehicle, as well as outside. So, if you want more power and less noise, then you've got to get Flowmaster 40 Series mufflers.

Flowmaster Super 44 Series Mufflers
Flowmaster Super 44 Series mufflers use the same technology as the original Super 40 mufflers—but also offer some distinct advantages. The Super 44s deliver a deep, rich tone with an improved flow path radius, optimum internal flow, and sound control engineering, all created with Delta Flow technology. They're the most aggressive, deepest sounding, highest performing 4 in. case street mufflers that Flowmaster has ever built. These American-made, all-black mufflers exceed OEM specifications for use on street cars, race cars, and sport trucks. Super 44s are ideal when dynamic sound, torque, and horsepower improvements are demanded in a smaller high performance muffler. Their maximum performance and improved flow path will generate more torque and power than ever before! If you really want to hear your exhaust system inside as well as outside of your vehicle, then order the Flowmaster Super 44 muffler best suited to fit your application.

MagnaFlow Universal Catalytic Converters
MagnaFlow universal catalytic converters by Car Sound form the basic building blocks for many applications. The main benefit of universal catalytic converters is that one unit may cover a wide variety of vehicle makes and models. Installing universal converters often requires the use of welding, cutting, and tube-bending equipment that is readily available to most professional installers. They are extremely well made, with features such as: * A ribbed body that minimizes expansion and distortion when the converter heats up. They form a channel that protects the cushioning mat from direct exposure to exhaust gasses, and hold the ceramic catalyst in proper alignment. * A 1/2 in. lap joint where the necks meet the body. The neck does not extend into the converter body, where it could hamper exhaust flow. * Manufactured with separate dies on different sized inlets. Putting larger neck sizes on smaller bodies would reduce the flow of the converter and the quality of the product. * A monolithic honeycomb catalyst. The ceramic is designed for maximum flow and surface area. The coating method is strictly controlled to maintain exact specifications. * Seam-welded close to the converter body for a strong, tight bond. Welding along the edge could allow the converter to expand like the folds in an accordion, allowing the catalyst to move around. * Heavier-gauge stainless steel, tip-to-tip. They do not use inferior mixed weights and materials. * An aluminized or stainless OEM-style ribbed heat shield that creates a rigid wall of protection against heat and adds to the structural stability of the converter.
