Audi S4 & S5 (B9) Valved Exhaust System (Incl. Remote)
*Includes Carbon Fiber Exhaust Tips*
The iconic CAPRISTO Valved Exhaust System offers the "best of both worlds" through its capability to produce an aggressive exhaust note under acceleration, and a more subdued sound for city driving.
This feature is possible using vacuum-actuated valve flaps that open and close depending on driving conditions and input from the driver. At lower engine speeds and during cruise operation the valves are closed and produce a deeper exhaust note. At wide-open throttle, the valves open releasing the full symphony of the engine.
The exhaust valves are backpressure-controlled and user programmable via the included CES-3 Control Module. The programmable control unit provides 3 modes operated via a remote key fob:
Cruise - Exhaust valves open at higher RPMs
Sport - Exhaust valves open at lower RPMs and hard acceleration
Open - Exhaust Valves Remain Open
Both the Cruise and Sport mode can be individually programmed for specific backpressure allowances to determine when the exhaust valves open. This allows precise control of the exhaust based on the driver's personal tastes and tolerance.
CAPRISTO Exhaust systems are engineered and manufactured utilizing advanced 3D Laser-Scanning, CAD Design, Digital prototyping, and CNC-bending/milling at our factory in Germany. Each system is made of high-grade T309 Stainless Steel and hand polished to a mirror finish. After extensive research, this specific alloy was chosen for its sonic resonance properties, low weight, and durability which are close to the properties of Inconel (used in F1).
*The exhaust system is designed to be installed directly into existing OEM mounting points
WARNING: Cancer and Reproductive Harm
CAPRISTO® guarantees its exhausts for a total period of 3 years from the date of purchase (i.e. the invoice date), as long as your CAPRISTO® Exhaust was purchased directly via CAPRISTO® or one of its authorized re-sellers. All electronic components carry a 1-year warranty. Product warranties are non-transferable. The warranty is limited to the exchange or repair of the defective part, and not the entire exhaust, unless needed. A situation in which the entire exhaust is defective is extremely unlikely. Transportation costs and labor as well as other claims for compensation for damages are not part of our guarantee.
All our sports exhaust systems are designed on the basis of serial cars. Power enhancements, turbocharger modifications or other changes in design, which entail an increase in emission temperatures, may alter your CAPRISTO® Exhaust, hence voiding its warranty. Any modifications on our products without consulting us before, result in an immediate expiration of our warranty.
Subject to a claim being made during the applicable Warranty Period and meeting the other conditions of this agreement, Customer's sole and exclusive remedy for breach of warranty is that Seller will repair or replace the defective Seller's Products or, in the case of other Warrantied Items, re-perform the defective service. Customer shall be responsible for all other costs and expenses, including, without limitation, removing, shipping goods, and reinstalling any products. Customer hereby acknowledges on a continuing basis that any exclusive and/or limited remedies available in this Agreement are reasonable and sufficient and that they will not fail of their essential purpose even if Customer may not take advantage of them in some circumstances by their terms.
Customers who do not purchase a Capristo Exhaust® product directly or from an Authorized Dealer DO NOT have a warranty, and are likely buying a counterfeit or damaged product. ONLY BUY FROM CAPRISTO® OR AN AUTHORIZED DEALER.
