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.

AWE Tuning Electronic Valve Simulators
Since the Touring Edition exhausts don't require the use of the S7's factory valves, they're eliminated. When this happens, the ECU stores what is known as a "soft code." While this code is not harmful, who wants it? Enter the AWE Tuning Electronic Valve Simulators. These simple devices plug right into the factory harness in place of the exhaust valves—and prevent any code from ever being stored in the ECU due to the removal of the exhaust valves. Plug them in. Start it up. Drive away. That simple. Comes as a set of two. Exhaust valve simulators are available for a variety of European autos, such as Audi, BMW, Mercedes-Benz, Porsche, and Volkswagen.

Go Fast Bits DV Plus Diverter Valves with TMS Advantage
Go Fast Bits offers DV Plus Diverter Valves with TMS (Turbo Management System) Advantage for a wide range of vehicles, particularly imports. GFB's DV+ solution couldn't be simpler—keep what works and replace what doesn't. GFB expands the DV+ range with a direct-fit solution for the weak factory diverter valve used on many European vehicles. The solenoid coil itself from the factory-fitted valve is great (the ECU opens it faster than any pneumatic valve so why replace it?)—but the weak point is the valve mechanism itself. So GFB's DV+ solves this problem by replacing just the valve parts with an anodized billet aluminum housing fitted with a brass piston machined to exacting tolerances. The end result is sharper throttle response, lightning-fast valve actuation, and it will hold as much boost as you can throw at it. Other manufacturers' products involve replacing the entire system with a traditional pneumatic valve, requiring long vacuum hose runs, additional parts for tapping into the intake manifold vacuum—plus either a different solenoid valve to actuate the pneumatic valve, or a ballast resistor to plug into the OE wiring loom. All these additional items result in a product that is slower, less responsive, more expensive and takes much longer to install. GFB's DV+ solution on the other hand is more responsive, less expensive, easier to install, and doesn't cause compressor surge/turbo flutter. Order the model recommended for your vehicle. Additional notes: * Retains the factory solenoid coil for seamless integration * Replaces plastic valve parts with metal for reliability and strength on chipped engines * Exclusive "pilot-actuated" valve mechanism for rapid response at high boost

Funk Motorsports Turbo Heat Shields
Funk Motorsports offers turbo heat shields for a wide range of (universal) applications, as well as vehicle-specific models for select BMW, Honda, Ford, and Subaru vehicles from 2002 and up. These turbo and/or turbo wastegate thermal blankets work to insulate the hot side and retain the heat within the exhaust gasses themselves. Hotter gasses accelerate faster, leading to them leaving the system sooner—improving spool up and throttle response. Insulating the turbo also helps to lower the amount of heat that dissipates into the engine bay and intake pipework. A cooler intake results in higher performance and more consistent power figures over time. The 4-layer shields are offered in three finishes: titanium twill, carbon fiber twill, and inside out (for turbos in contact with a heat source). Additional details: * Inside-out blankets have internal material mirrored on the outside, as well * Available for a variety of turbocharger and wastegate styles * A turbo is an absolute furnace within the engine bay. Excess heat produced by the turbo can cause devastation to surrounding sensitive components. Protect anything from oil lines, coolant lines, electronics, and even bodywork positioned close to the turbo from the dangers of excess heat * Funk shields feature specifically developed thread construction to allow for exceptional durability when removal is necessary for routine turbo maintenance. The new fireproof ultra-high temperature stainless steel thread is around 1mm in diameter and can now remain highly durable with temperatures in excess of 1,300 degrees C * New, thicker internal heat lagging insulation provides up to 3x improved heat reduction. This insulation wool is created from a ceramic silica complex matting to improve durability over prolonged heat cycles, as well as insulation quantities * ROHS tested and approved to ensure compliance and desired parameters * NOTE: Turbo blankets are not flammable. However, if any flammable fluids are introduced into close proximity of the blanket, the blanket could become a suitable ignition source for a flame to be produced. Please ensure that all necessary precautions are taken in regard to the appropriate maintenance of all oil and fuel lines and fittings surrounding the turbo charger and fuel injection system. Funk Motorsports takes no responsibility for fluid contamination their products.
