Does the APR Catback Exhaust for B9 RS5 fit the facelift car?

Yes, with one check. Some B9.5 facelift cars have an updated valve motor, and those with valve actuator part number 8S0-133-246-D need APR adapter EXH0712 to work with the Catback Exhaust for B9 RS4 and RS5. APR supplies that adapter free of charge with proof of purchase.

How much power does the APR RS5 exhaust add?

APR measured 9 horsepower and 15 lb-ft of torque at all four wheels. The gains come from dual 2.75 inch front and mid pipes, a 3.5 inch center pipe and straight-through mufflers and resonator that reduce restriction for the 2.9 TFSI twin-turbo V6.

Does the APR RS4 and RS5 exhaust keep the factory valves?

Yes. The rear mufflers carry valves that stay fully integrated with the factory control system, opening automatically during aggressive driving and closing at cruise for a quieter profile. Apart from the adapter some B9.5 cars need, no extra parts are required.

What tips come with the APR B9 RS5 exhaust?

Two oversized 7.25 by 5 inch RS-style oval tips in diamond black, each carrying a subtle APR logo, come with the system. They keep the Audi Sport oval shape at the rear while giving it a darker, more purposeful finish than the factory tips.

Why is a tunnel brace included with the APR RS5 exhaust?

The larger piping needs more room in the transmission tunnel than the factory brace allows. APR includes an upgraded tunnel brace that clears the oversized pipes while doing the job of the factory part, so the system installs without any cutting or modification.

Description

APR Catback Exhaust for B9 Audi RS4 and RS5

APR’s Catback Exhaust for B9 Audi RS4 and RS5 keeps the single oversized center pipe that sets the RS models apart, then enlarges everything around it for the 2.9 TFSI twin-turbo V6. Dual 2.75 inch front and mid pipes start high in the engine bay and merge through a cast Y-junction into a 3.5 inch center pipe, before splitting to valved rear mufflers, quad 2.5 inch outlets and two 7.25 x 5 inch RS-style oval tips in diamond black. APR measured 9 horsepower and 15 lb-ft at all four wheels. It is the exhaust for an RS5 owner who wants more voice from the V6 without losing the Audi Sport look at the back.

Design and Performance

A straight-through Helmholtz resonator with a sound-cancelling port minimizes drone without restricting the center pipe, and the rear mufflers combine sound absorption with valves that stay fully integrated with the factory control system. Electropolished cast splitters keep the transitions smooth, and an upgraded tunnel brace is included to clear the larger piping.

Electropolished cast Y-junctions and splitters
Straight-through Helmholtz resonator with a sound-cancelling port

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.
