Treat your S63M equipped BMW with our beautiful downpipe + midpipe and increase the horsepower & torque of your car while getting a nice, aggressive exhaust note to match.
The CAP Cast Downpipes Exhaust replaces the restrictive OEM catalyst systems and upgrades it to a superior & better flowing system that improves on many characteristics that car enthusiasts look for. Expect faster turbo spool, less turbo lag, better throttle response, more horsepower & torque and last but certainly not least: an exhilarating improved exhaust note.
Key Features:
Match your V8 equipped BMW with a downpipe it deserves, make the turbo work to its maximum efficiency! The F90 BMW M5 & M8 deserve the beautiful CAP downpipe & midpipe combo to wake its glorious engine up and do what it was meant to do with the increased flow & efficiency.
Heat shield (optional) - Using the highest quality heat shield available, protect your engine bay from the heat with our heatshielded downpipes!
Please note the regular downpipe & midpipe combo is not heatshielded, you must select the heat shield option for them to be heatshielded.
When it comes to choosing between heat shielded and non-heat shielded downpipes for your BMW, understanding the pros and cons of each option will help you maximize performance and protect your engine components.
Here’s a quick overview to make things easy:
Heat shielded downpipes offer several advantages that can significantly improve your BMW's performance and longevity:
Reduced Heat Soak: By effectively managing exhaust heat, heat shields prevent excessive temperatures from affecting nearby components, reducing the risk of heat soak and maintaining optimal engine performance.
Enhanced Engine Bay Protection: Heat shields act as a barrier, protecting sensitive components such as electrical systems, fuel lines, and wiring harnesses from heat-related damage.
Improved Air Intake Temperature: By keeping engine bay temperatures lower, heat shields help maintain cooler air intake temperatures, leading to better combustion and increased power output.
Optimized Exhaust Flow: Heat shielding helps maintain higher exhaust gas temperatures, which can improve exhaust flow and scavenging, potentially leading to better turbocharger performance and faster spool times.
Noise and Vibration Reduction: Heat shields can also help dampen noise and vibrations, contributing to a more refined driving experience.
For performance enthusiasts looking to maximize their BMW's potential, the benefits of heat shielded downpipes often outweigh the negligible increase in weight and cost.
NOTE: The removal of factory catalytic converters will trigger a check engine light. Software tunes are recommended to maximize the power gains.

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.
