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.

APR Turbo Muffler Delete Pipes
The APR turbo muffler delete pipes are designed to replace the factory muffler with a straight, uninterrupted piece. The delete pipes are CNC-machined from billet aluminum and anodized black. To ensure proper sealing, APR's engineers took a two-part approach. A Viton® seal is included and forms a seal between the base of the muffler housing and the new piece. With the seal in place and the outer flange installed, the muffler delete tube screws into place, forming a full, uninterrupted path for airflow. For a smooth, turbulence free, and leak-proof path for airflow existing in your turbo, install one of the APR turbo muffler delete pipes. Additional features include: * Removes factory turbo muffler * 2-piece design with gasket eliminates leaks and factory tolerance issues * Enhanced turbo sound * Faster spool * Better power delivery

Go Fast Bits DVX Diverter Valves
Go Fast Bits' DVX takes the extremely popular DV+ diverter valve and adds dual venting outlets, along with GFB's patented venting bias adjustment system. So, not only do you get improved boost holding and throttle response, you have total control over your blow-off sound volume! The DVX is not just a noise maker (like BOV spacers); by modifying the valve operation method, it offers the same performance benefits that the DV+ does. It retains ECU control for the fastest possible operation. No other blow-off valve has the advantage of GFB's venting bias adjustment, allowing you to alter the blow-off sound simply by moving the adjustment lever. GFB's DV+ design solves the longevity and boost leaking issues that are common with factory diverter valves, and also changes the operation method to "pilot actuation" to ensure better performance on stock or modified engines. Furthermore, these benefits won't cost you a fortune! Rather than throwing the entire factory diverter valve system in the trash (like other manufacturer's "solutions"), the DV+ keeps what works and replaces what doesn't. Order the model recommended for your vehicle.

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

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.

COBB Tuning Turbo Blankets
COBB Tuning turbo blankets not only look cool under the hood of your vehicle, but they also offer multiple benefits that can be found on both sides of the blanket. Obviously, they help prevent the turbo from heat soaking neighboring components in the engine bay, but the real magic happens on the underside. With a turbo blanket installed, the turbo RPM acceleration improves, which leads to faster turbo spool and being able to achieve peak torque more quickly. This insulation also helps reduce heat-related wear, potentially improving the longevity of the turbocharger and other engine parts. Order the blanket designed for your make/model. Key features and benefits: * Turbo blankets are constructed with a fragmentized fire-retardant volcanic rock outer layer * Turbo blanket insulates the turbine housing, and act as a shield, preventing the high heat from the turbo from dissipating into the engine bay and damaging sensitive components like rubber and plastic hoses, wiring, and painted surfaces * Designed to limit the amount of heat that is transferred from your turbocharger to your engine bay, as well as keeping hotter exhaust gases that exit the system faster through decreased density * By limiting the amount of transferred heat can help extend the life of underhood components, decrease intake temps, and improve the response from your car
