How much power does the APR Catback Exhaust for C8 RS6 add?

APR measured 9 horsepower and 16 lb-ft of torque at all four wheels with the Catback Exhaust for C8 RS6 and RS7. The gains come from a full-length dual 3 inch path, cast inlets and straight-through mufflers that let the twin-turbo V8 breathe with fewer restrictions.

Does the APR RS6 and RS7 exhaust keep the factory valves?

Yes. The valve-controlled rear mufflers stay on the factory control system, so drive select still decides when they open. Open, the exhaust takes an uninterrupted path to the tips; closed, it is routed through a smaller 2.5 inch path for a quieter cruise.

What tips come with the APR C8 RS6 exhaust?

The system includes two oversized RS-style oval tips measuring 8.23 by 4.76 inches, finished in diamond black with a subtle APR logo. They fill the rear of the RS6 Avant and RS7 Sportback with the shape Audi Sport uses, in a darker finish.

Will the APR RS7 exhaust drone at highway speed?

APR built a Helmholtz resonator into the multi-chamber rear muffler to reduce drone frequencies without restricting the open-valve path. When the valves close at cruise, the exhaust also switches to a 2.5 inch sound reduction path, so long trips stay comfortable for everyone in the car.

Does the APR system replace the whole exhaust on the RS6?

It is a full-length system that starts high in the engine bay and runs to the tips, replacing everything behind the factory hardware at the front. It installs with precision brackets and OEM-style slip clamps, and the factory valve actuators continue to work with it.

Description

APR Catback Exhaust for C8 Audi RS6 and RS7

APR’s Catback Exhaust for C8 Audi RS6 and RS7 is a full-length system for the 4.0 TFSI twin-turbo V8, starting high in the engine bay and running to a pair of oversized RS-style oval tips in diamond black. The whole path steps up to dual 3 inch mandrel-bent T304 stainless with cast inlets and smooth transitions, and APR measured 9 horsepower and 16 lb-ft at all four wheels with a bold, aggressive growl at full throttle. With the valves closed, a separate 2.5 inch route keeps the car civilized. It is built for the RS6 Avant or RS7 Sportback owner who wants both the sound and the look of the car to move up a level.

Design and Performance

With the valves open, exhaust travels uninterrupted from the front of the system out through the tips, and a Helmholtz resonator inside the multi-chamber rear muffler cuts drone without restricting that open path. With the valves closed, the gases take a smaller 2.5 inch sound reduction route, which brings the volume down for cruising. The valves remain under factory control, so the drive modes behave exactly as before.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
