Can Auto Performance has been building exhaust products for Audi's performance V6 platforms since the B8 S4 days. The same obsession with material quality, weld integrity, and fitment accuracy that earned CAP's B8 S4 downpipes a zero-failure track record is what went into these downpipes for the EA839 2.9TT.
The EA839 is one of the best engines Audi has ever built. From the factory it's also one of the most muzzled. The twin-turbo exhaust note gets filtered down to something polite and forgettable. These downpipes fix that.
Pull the OEM cats and the character that's been sitting underneath comes through. Louder, rawer, with actual turbo presence at every RPM. Spool response tightens up and EGTs drop under load. If you're building toward Stage 3, downpipes are required hardware at that point anyway. Get them done now
304 Stainless Steel - T304 austenitic stainless throughout, pipe body, flanges, and heat shield mounting. T304 handles the thermal cycling from EA839 exhaust temperatures without scaling, pitting, or degrading. It's also corrosion-resistant in road-salt environments, which matters for Canadian and northern US climates where most of these cars are driven year-round.
TIG Welded and Back Purged - Every CAP downpipe is TIG welded with inert gas back purging at the weld zone. Back purging prevents oxidation on the interior weld bead, the surface that exhaust condensate and acids contact first. Sugared welds corrode from the inside out. Back-purged welds don't. The result is a clean, full-penetration bead on every unit with no porosity and no variation between production runs.
CNC Machined Flanges - Machined to OEM bolt pattern at both the turbo outlet and midpipe junction. Bolt-on installation, no modifications to the OEM exhaust system required.
Integrated Heat Shielding - The EA839's underbody packaging puts the downpipes in close proximity to brake lines, chassis components, and wiring. The heat shielded variant replicates OEM-level thermal protection, keeping radiant heat away from everything around it.
CAP Limited Lifetime Warranty - No time limit. No exclusions for material or weld defects. The same warranty CAP offers on every exhaust product.
On stock turbos, removing the cats on the EA839 does not add measurable peak power. What changes is exhaust note, transient spool responsiveness, and EGTs. If you're after horsepower, tune first. This is the mod you do because you want your RS5 to sound like an RS5.
The removal of factory catalytic converters will trigger a check engine light. Software tunes are recommended to maximize the power gains.

Please read before ordering. Eurosport Performance does not carry live inventory on this site. Most products are ordered for you directly from the manufacturer or our suppliers, and we follow their lead times. Placing an order confirms you have read and accepted the availability terms below.
| In stock
Ships within 24 to 48 hours
Products marked in stock are on our shelves in Montreal and leave within one to two business days.
|
Ordered for you
Most orders ship in 5 to 7 business days
Everything else is ordered from the manufacturer or supplier when you order. Delays can occur; if they do, we contact you.
|
|
Supplier lead times apply
If a product is not listed as in stock here and is on backorder at the manufacturer, it will most likely be on backorder for us too. We will tell you as soon as we know.
|
We keep you informed
You receive a confirmation when the order is placed, a notice if a delay comes up, and tracking the moment it ships.
|
Only products explicitly marked in stock are on our shelves. For everything else, the fastest way to know the current lead time is to ask us before you order; we check with the supplier and reply with a date.
Confirmed means we have placed the order with the manufacturer or supplier on your behalf. Shipping follows once the part reaches us or ships directly to you, usually within 5 to 7 business days for products that are available at the source.
We tell you as soon as the supplier confirms it, with the expected date when they give one. You can keep the order open, switch to an alternative we suggest, or cancel for a full refund before the part ships.
Yes. Any order that has not shipped can be cancelled by contacting us, and the refund goes back to your original payment method. Please contact us rather than opening a dispute with your bank: a cancellation takes us minutes, a chargeback takes weeks and freezes the refund in the meantime.
Sometimes. Larger or special-order items can ship to you directly from the supplier to save days in transit. You still receive tracking from us either way.
Orders ship from Montreal or directly from our suppliers. For Canadian addresses the price you pay is the price, with no import or duty fees added on delivery. See our shipping policy for details.
You get an email with the tracking number the moment the label is created, and you can follow the order in your account on the site or in the SPECD app.
Want a lead time before you order? Email us or use the contact page with the product name and your vehicle, and we will confirm availability with the supplier.
Products are warrantied by their manufacturer. Eurosport Performance is an authorized reseller: every part we sell is covered by the manufacturer's own warranty, with its own terms and duration. Claims go through us, so you deal with Eurosport Performance rather than a form on the brand's site, but whether a claim is accepted is the manufacturer's decision.
|
Manufacturer terms apply
Duration and coverage are set by the brand and differ from one to the next: some cover one year, some a lifetime, some only the original purchaser. The brand's warranty page is the reference; ask us if you cannot find it.
|
We file the claim for you
Contact us with your order number, photos and a description of the issue. We open the claim with the manufacturer, follow it up, and arrange the repair, replacement or credit they approve. The manufacturer decides whether the claim is accepted.
|
|
Fitment guarantee: North America only
We guarantee fitment for vehicles sold in the North American market. Vehicles from other markets are out of scope; specifications differ, and it is the customer's responsibility to confirm compatibility before ordering.
|
No warranty on tuning files
ECU and TCU tunes and other software files are sold without warranty and are not returnable once delivered or flashed. Tuning can affect your vehicle's factory warranty; please read the brand's terms before purchasing.
|
|
Proof of purchase
Your Eurosport Performance order is the proof of purchase every manufacturer asks for. Keep the order confirmation; it is also in your account on the site and in the SPECD app.
|
What is usually not covered
Damage from improper installation, modification, abuse, racing or an incorrect application for the vehicle, and normal wear items such as pads, clutch discs and filters. Shipping and labour are covered only when the manufacturer's terms say so.
|
It is the manufacturer's warranty for that product. Where the brand publishes it, we note it in the description; otherwise contact us before ordering and we will confirm the exact terms with them.
Stop using it if it is a safety-related part, then contact us with your order number, clear photos, and when and how the issue appeared. Do not return anything until we confirm the claim; manufacturers often require an inspection or an authorization number first.
The manufacturer. We prepare and submit the claim, provide the proof of purchase and push for a fair outcome, but acceptance, replacement or credit is their call under their terms. We pass their decision on to you as soon as we have it.
It depends on the manufacturer. Simple cases are approved in days; claims that need the part inspected can take a few weeks. We keep you updated at each step and push when it drags.
No. Tuning files are software; once delivered or flashed they cannot be returned, and they carry no warranty from Eurosport Performance or, in most cases, from the tuner. Support for the tune itself (revisions, flashing questions) comes from the tuning brand under its own terms.
No. Our fitment guarantee covers vehicles sold in the North American market only. European, Japanese and other market vehicles can differ in engines, electronics and dimensions, and a part listed for the North American model is not guaranteed to fit. If you order for one of these vehicles, confirming compatibility is your responsibility, and fitment issues on such vehicles are not covered by returns or warranty.
Labour is not covered unless the manufacturer's terms specifically include it. Having the part installed by a qualified shop protects your claim: improper installation is the most common reason a manufacturer declines.
No. Returns cover unused parts you no longer want, under our refund policy. Warranty covers a part that fails in use, under the manufacturer's terms. If you are unsure which applies, contact us and we will point you to the right one; please do not open a bank dispute, as it pauses both processes.
Questions about coverage before you buy? Email us with the product and your vehicle and we will confirm the manufacturer's terms.
