Do the Boost Logic Downpipes for C8 Audi RS7 fit the RS6 Avant?

No. The Downpipes for C8 Audi RS7 are listed for the RS7 only. The RS6 Avant shares the 4.0 TFSI engine, but Boost Logic sells separate RS6 downpipes under their own part number, so RS6 owners should order that listing instead. Contact Bulletproof Automotive with the VIN if there is any doubt about which part fits the car.

How many downpipes are in the set?

The set contains two downpipes, one for each turbocharger. The 4.0 TFSI V8 mounts both turbos in the valley between the cylinder banks, so each bank has its own downpipe. Boost Logic does not publish a hardware list, so confirm with Bulletproof Automotive which gaskets and clamps come with the pair before the car goes on the lift.

How do these compare to the RS7 downpipes with Sport Cats?

Boost Logic sells two RS7 downpipe listings for the same car. The version with Sport Cats is documented by Boost Logic with TIG-welded construction, direct bolt-on fitment and support for upgraded turbos. This listing is the lower-priced version and carries only brief vendor detail, so ask Bulletproof Automotive for the full specification before choosing between them.

Is a tune required after installing these downpipes?

Boost Logic does not say whether a tune is required. Exhaust changes directly behind the turbos alter flow through the system, and the tuner who looks after the car is the right person to confirm whether a calibration update is needed. Plan the software and hardware changes together so the car is ready to drive once the install is finished.

Will these downpipes fit a 2019 or 2020 RS7?

Yes, if the car is a C8 generation RS7. Boost Logic lists fitment as the 2019 and later RS7, which covers the C8 from its European launch, while US cars start with the 2021 model year. The earlier C7 RS7 uses a different part, and Boost Logic sells separate downpipes for the 2013 to 2018 4.0 TFSI cars.

Boost Logic Downpipes for C8 Audi RS7

Boost Logic’s Downpipes for C8 Audi RS7 are a two-piece set for the twin turbo 4.0 TFSI V8 in the current RS7 Sportback, one downpipe for each turbocharger. Boost Logic’s own listing for this part confirms fitment for the 2019 and later RS7 and very little else, so this page keeps to that and to what the vendor photos show. They suit an RS7 owner who wants Boost Logic downpipes from the same family it builds for the RS6 and RSQ8 on this engine. Buyers who want the construction and performance detail spelled out should look at the RS7 version with Sport Cats, which Boost Logic documents far more fully.

Features

Sold as a pair, one downpipe for each turbocharger
Built for the hot vee layout of the 4.0 TFSI V8, where both turbos sit between the cylinder banks
Black finish with Boost Logic branding, as shown in the vendor photos
From the same Boost Logic downpipe family as its RS6 and RSQ8 4.0 TFSI parts

Applications

Audi RS7: C8 | 2021-present | 4.0L TFSI Twin Turbo V8

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.
