AWE Tuning 13-16 Audi B8.5 S4 3.0T Touring Edition Exhaust System - Chrome Silver Tips (102mm) Welcome to the mothership of 3.0T exhausts. Our 3.0T exhaust system represents the most comprehensive exhaust development project in our company history. The 3.0T systems have paved the way for future exhaust technologies that can now be found in most every AWE Tuning ® exhaust product. We have spent considerable time and effort during development to achieve remarkable civility when idling and at part throttle cruising, while also producing a war-cry wail when full throttle is applied. Handcrafted in-house, these systems command respect while remaining sophisticated, refined, and powerful, all at once. Highlights of the S4 3.0T Touring Edition System Handcrafted, every detail drives toward maximum performance, quality and perfect sound: Featuring AWE Tuning 180 Technology® +8 hp, +9 tq at the crank Increased pipe diameter to 2.5” to better let the engine exhale Strategic elimination of factory mufflers to release tone when uncorked Available with chrome silver or diamond black adjustable tips, 90mm or 102mm Engineered, developed, tested and manufactured in-house Thick .065" wall T304 stainless steel tubing Stainless steel TIG welds High quality stainless steel band clamps Stainless steel center muffler with OEM grade stainless steel wool and German composite packing material Optional downpipes for fine tuning sound volume Lifetime Exhaust Warranty Sound Perfection: AWE Tuning 180 Technology® As exhaust gases exit the 3.0T engine and flow into an AWE Tuning 180 Technology® equipped resonator, they pass through strategically located ports, and into reflection chambers. Sound waves, carried by these exhaust gasses, bounce off the walls of the reflection chambers. By controlling the size and location of the ports and the chambers, we also control when the sound waves exit the chambers. The specific timing of when the reflected sound waves re-join the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies. More on AWE Tuning 180 Technology® in the tab above. About the downpipes We offer our resonated and non-resonated downpipes. Our resonated downpipes (strongly recommended for S-tronic cars) feature resonators larger than the stock units in order to produce a mellow sound volume. Our optional non-resonated downpipes are suited for owners seeking a "loud" and aggressive sounding system. Both our resonated and non-resonated downpipes feature larger than stock tubing diameter. Looking for a lower cost option? Look no further than the AWE Tuning ® Track Edition Exhaust. For those open to a louder part-throttle experience, we're introducing the AWE Tuning ® Track Edition Exhaust. Same power and craftsmanship, with less mufflers and price. More, right here . Read this, too As with all AWE Tuning ® exhaust products, each TIG weld is hand finished internally, and flange openings are size matched to their ports, all to produce the smoothest flow possible. It is this intensive attention to detail that sets AWE Tuning ® exhaust products heads and shoulders above the rest. Notes: In limited cases, the factory downpipes have been known to emit minor rattling noises when paired with the AWE Tuning S4 exhaust system. The possibility of rattling is eliminated with the addition of AWE Tuning downpipes.
