South Bend Clutch Stage 2 Daily Driver Clutch Kits

South Bend Clutch Stage 2 Daily Driver clutch kits are engineered for vehicles with high performance modifications. The heavy-duty pressure plate has an increased clamp load with little or no increase in pedal pressure to offer stock feel, while increasing strength and durability. The organic disc material has a high metal content that increases the co-efficient of friction by two times over a stock lining. This greatly increases rotational strength up to a 12,000 rpm burst point for high performance. South Bend Clutch Stage 2 Daily Driver clutch kits are recommended for daily performance, street, and moderate race vehicles. Select the kit designed for your application needs.

South Bend Clutch Stage 3 Daily Driver Clutch Kits

South Bend Clutch Stage 3 Daily Driver clutch kits are recommended for single mass flywheel (SMF), when original design is dual mass flywheel (DMF). These clutch packages are designed for high-horsepower vehicles desiring a start performance similar to OE. The pressure plate is race engineered (SS) and SFI-approved with significant load increase over stage 1 and 2 pressure plates (+600-800 lbs.). Expect a pedal effort increase of 20 to 25 percent. Discs are assembled with heat-treated wear-resistant hubs, as well as drive plates and springs for high-load transfer and dependable operation. The sprung centers on the disc, in conjunction with the marcel fin between the linings, create a dual dampening effect that simulates OE start performance. A performance organic friction material with a high metal content increases torque and rpm capability—and maintains low operating temperatures, which reduce wear and glazing. South Bend Clutch Stage 3 Daily Driver clutch kits are the perfect match for your high performance street machine and occasional track use. Order the kit recommended for your application.

MagnaFlow Direct-Fit Catalytic Converters

MagnaFlow direct-fit catalytic converters are designed for easy bolt-on installation for the professional installer. Welding, cutting, and tube-bending equipment are not required. These cats feature a ribbed body that minimizes expansion and distortion when the converters heat up. The ribs form a channel that protects the cushioning mat from direct exposure to exhaust gases, and they hold the ceramic catalyst in proper alignment. MagnaFlow converters use a monolithic honeycomb catalyst; the ceramic coating is designed for maximum flow and surface area, and the coating method is strictly controlled to maintain exact specifications. Improper coating could result in flow restrictions or an emissions test failure. These converters are designed to exact OE specifications and are available for the most popular vehicle makes and models.

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.
