Fits All Gen 1 and Gen 2 B58 Engines (including Mk5 Supra)

Unlock your engine's full potential with our precision-engineered B58 High-Flow Catless Downpipe. Designed for true performance enthusiasts, this downpipe features a genuine 4.5-inch or 5-inch diameter from turbo to exhaust connection, delivering superior exhaust flow and turbo efficiency. Unlike competitors, our design ensures no restrictive tapering right after the turbo, preserving peak flow and maximizing your engine’s power output.

Engineered for bolt-on compatibility with your OEM exhaust, installation is hassle-free. Alternatively, for those running custom setups, the downpipe can be cut at the taper and welded to a larger exhaust system, aided by a high-quality flex joint to ensure a seamless fit.

Key Features:

  • True 4.5-inch or 5-inch diameter for maximum flow and reduced backpressure
  • Enhances turbo performance by relieving stress and improving efficiency
  • Compatible with both OEM and custom exhaust systems
  • Built to last with premium materials, ensuring durability under extreme conditions

For Off-Road and Track Use Only: Installing this product on a street vehicle is illegal in many regions. We do not endorse or sell for road use.

Fitment: This downpipe is compatible with all BMW and Toyota B58-powered models, including:

  • BMW 340i / 440i / M240i / M340i / M440i / M140 (2015–2023)
  • BMW X3 / X4 / X5 / X7
  • Toyota Supra A90 / A91

Really good quality metal and welding!! Also designed well, even better than options on the market that are 4 times the price. Fits well in a 2021 BMW X3 M40i G01. Makes loud boom.
