Description

Unlock the full potential of your BMW B58 engine with the Catless Downpipes, engineered to enhance both performance and exhaust sound. These downpipes deliver a more aggressive, deeper tone while significantly improving exhaust flow to maximize horsepower and torque gains across the RPM range.

Constructed from high-quality 304 stainless steel with precision TIG welding and CNC-machined V-band flanges, these downpipes ensure a perfect OEM-fit replacement that reduces turbocharger thermal load and backpressure for quicker spool and improved throttle response.

Available in brushed, polished, or black thermal coating finishes, the downpipes include an optional EGT sensor bung for added monitoring flexibility.

Key Features:

  • Precision 304 stainless steel construction for durability and corrosion resistance

  • Direct OEM fit, 100% replacement for factory downpipes

  • Reduced turbo heat load and backpressure for increased power and torque

  • 4.5” piping with smooth flange transitions for optimal airflow

  • TIG welded for superior strength and quality

  • Optional EGT bung included (capped if not used)

  • Compatible with stock exhaust and most aftermarket systems

Performance Benefits:

  • Higher maximum horsepower and torque

  • Sustained torque across a wider RPM range

  • Improved throttle response and quicker turbo spool

  • Proven durability with track-tested reliability

Fitment:

  • BMW M140i / xDrive 2016-2019 (F20)

  • BMW M240i / xDrive 2016-2019 (F22/F23)

FAQ

Are these made from real carbon fiber or just overlays?

All of our products are full carbon fiber. Each product listing specifies the construction material, and we only source high-quality parts that are tested for durability and built to meet or exceed OEM standards.

How long does shipping take and where are orders shipped from?

Shipping times vary by location. U.S. orders typically arrive within 5–7 business days, international orders within 7–16 business days, and made-to-order items may take 1–3 weeks. Full delivery details are provided in your confirmation email. For any questions, reach us at aurenzioservice@gmail.com.

Do I need a professional to install, or can I do it myself?

Many of our parts are designed for simple bolt-on installation and can be done at home with basic tools. For more complex items, such as aero kits or performance components, we recommend professional installation to ensure the best fit and results. Each product page includes installation notes and difficulty levels.

Are your parts tested for quality and durability?

Yes — every product goes through strict quality checks and is either TUV-certified, ISO-certified, or tested by our in-house team and trusted installers. We only offer parts we’d confidently run on our own cars.

What if the product doesn’t fit?

We offer easy, hassle-free returns within 14 days of delivery. If the fitment issue is on our end, we’ll cover return shipping. For other cases, exchanges are simple. Full details can be found in our Returns & Warranty Policy
