C7.5 A6/A7 3.0T Valved Cat-Back Exhaust System & Luft-Technik Performance Intercooler Kit

C7.5 A6/A7 3.0T Valved Cat-Back Exhaust System

True automotive passion comes in many forms. For us, we've found driving euphoria with our new ECS Valved Exhaust System. 

Enjoy your C7.5 A6/A7 with the most engaging, race-inspired, performance-valved exhaust system. Intoxicating exhaust notes fuel your desire to push your engine to its limits with every ounce of power and every engine revolution. Experience your driving passion with our ECS Valved Exhaust System allows for MMI control and operation of the valves

The full exhaust system is made from high quality brushed T304 stainless steel with TIG welded joints for an exceptional look and durability. Exhaust gases are channeled through the integrated x-pipe, your choice of either a resonator or a resonator delete section, and then to the 3 chamber, in house designed mufflers. With this system, you, the driver, are in control of where the exhaust gases go from here. 

In normal, comfortable driving conditions, the valve remains closed and exhaust gases are directed through the channels of the mufflers, where sound reduction takes place. Once the exhaust valved are opened it unleashes a straight-through, raw, unedited exhaust symphony.

When paired with our standards of quality and design requirements here at ECS Tuning, we can provide your C7 A6/A7 a perfect blend of performance and an interactive driving experience. Through multiple design iterations and stringent product testing, we have engineered our exhaust system to not only free up horsepower but to provide trouble-free installation.

Our ECS Valved Exhaust System was designed, engineered, tested and quality inspected by our Research and Development team in our Wadsworth, Ohio facility. We strive for the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long term product testing.

Audi C7/C7.5 A6/A7 3.0T Luft-Technik Performance Supercharger Intercooler Kit

The ECS Tuning Luft-Technik Performance Supercharger Cooling Kit was designed and engineered in-house to provide you with a direct bolt-on system to improve consistency in engine performance, decrease intake air temperature, increase resistance to heat soak, and drastically lower temps!

The R&D team at ECS Tuning has spent countless hours creating and testing a system to optimize performance and efficiency while providing the clean look that Audi owners have come to expect. We designed the cooling system to directly mate with the existing OEM piping, resulting in a simple install.  

ECS Tuning's Luft-Technik heat exchanger features an aluminum tube and fin core with fabricated 5052 aluminum end tanks. The core offers a 140% increase in frontal area compared to stock heat exchanger and designed to increase power, improve efficiency, and reduce heat soak. Our engineers provided a proper fit by utilizing factory mounting locations, making installation completely reversible.

Increasing the surface area by using a larger core design with dual coolant flow channels per pass, we were able to lower IAT temps by 32 degrees Fahrenheit resulting in max gains of 19 WHP and 16 WTQ!  

Performance Data:

• Reduced intake air temperatures

• Increased resistance to heat soak

• Improved consistency in engine performance

• 140% increase in frontal area! 399 sq in vs stock at 165 sq in

• With SC Pulley and Stage 2 tune installed 75 deg F ambient:

  • IAT reduction of 32 deg F by 5th back to back dyno pull

  • Peak IAT of 159 deg F by 5th back to back dyno pull

  • IAT reduction of 25 deg F on 1st dyno pull

  • Peak IAT of 141 deg F on 1st dyno pull

• Max gains of 19WHP @ 6900 RPM and 16 WTQ @ 6400 RPM

• Peak WHP 416 @ 6900 RPM

• Peak WTQ 364 @ 6400 RPM

Features:

• Large volume, dual pass aluminum heat exchanger

• Dual coolant flow channels per pass

• Integrates with factory heat exchanger pump and lines

• Fluorosilicone lined custom molded silicone hoses

• Dual bleed ports with billet bleeder screws to remove all air from the heat exchanger

• Fabricated 5052 aluminum end tanks

• ECS billet bleeder screws for the supercharger 

For help with installation we have provided you with a PDF, available under the Installation category on the product page, to guide you through fitting on your new front mount intercooler!
