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.

EBC 3GD Series Sport Rotors

EBC 3GD Series Sport rotors are dimpled and slotted and precision-machined using premium-quality castings. Designed with wide-aperture scraper slots and blind-drilled holes, these 3GD rotors draw cooler air in and reduce temperatures for greatly reduced brake fade. Plus, their dimpling helps them to avoid stress cracks. Able to expel dirt, dust, and gases, EBC Sport rotors also maintain flat and parallel pad wear for better pad contact and better braking. These high performance rotors are available in a sporty silver corrosion resistance finish that not only looks great, but also prevents corrosion. Enhance the performance and looks of your car with EBC 3GD Series Sport rotors. Additional information: * Dimpled rotors were invented by EBC; often imitated because of its pad degassing without "through drilling" holes which promote rotor cracks * 3GD rotors passed European R90 brake safety tests and were shown to run 100 degrees F cooler than non-slotted rotors * Directional--the sweeping grooves and spotted pattern should point to the rear of the vehicle * All slotted rotors increase in air noise as the rotor passes beneath the pads under normal driving and braking; EBC's sister USR Sport rotor range is much quieter yet offers similar performance * Solid rotors are also available for some vehicle makes and models

APR 3.0 TFSI Supercharger Drive Kits

APR 3.0 TFSI supercharger drive and crank pulley upgrade kits have been designed to dramatically increase the rotational speed of the factory supercharger. When combined with APR's Ultra-Charger Throttle Body Upgrade in a dual pulley setup, the system is alleviated of power robbing inlet restrictions, allowing the engine to achieve exciting new levels of performance! The supercharger drive pulley decreases the diameter of the factory pulley from 63.25mm to 57.75mm, which in turn spins the supercharger 9.5 percent faster. This results in a healthy bump in horsepower and torque across the entire rpm range with the supercharger operating at a higher rate of speed. The pulley is CNC-machined from billet stainless steel, E-coated factory black for an OEM appearance and is press fitted to the factory supercharger unit. The supercharger crank pulley increases the diameter of the factory pulley from 162mm to 187mm, which in turn spins the supercharger 15.4 percent faster. This results in a larger bump in horsepower and torque across the entire rpm range, as the supercharger is spinning at an even higher rate of speed. The pulley is CNC-machined from light weight billet aluminum with weight saving pockets throughout and has an anodized black finish and includes new crank pulley bolts. It retains the factory harmonically balanced crank pulley and bolts on top of the existing unit. Upgrading both the supercharger drive and crank pulleys results in the factory supercharger spinning faster than stock, which results in an even higher horsepower and torque gain across the entire rpm range. However, at the airflow levels achieved with a dual pulley setup, maximum power is severely restricted by the factory throttle body unit. APR's Ultra-Charger Throttle Body Upgrade is necessary to take full advantage of the dual pulley configuration and is available in platform specific variations for the B8/B8.5 A4/A4/S4/S5, Q5/SQ5 and C7 A6/A7.
