The CorkSport Advantage

Mazda 3 turbo downpipe upgrade


Designed with 3D Scan data and CAD, the CorkSport 80mm Downpipe is made to fit just like OEM, while allowing for greater exhaust flow! Our two-piece design ensures perfect fitment with the Turbocharger and OEM and aftermarket exhaust systems. The two-piece design also provides a much easier installation process without having to wrestle with or snake a big and cumbersome pipe into place.

Power Potential:

The CorkSport downpipe offers bonus power potential for your Mazda 3/CX30/CX50! By eliminating the poorly bent 65mm piping of the OEM downpipe and the restrictive catalytic converter, the CorkSport downpipe offers minimal restrictions and greater peak flow with a 300cel high flow CAT. The cast bellmouth provides a smooth transition from turbo to piping, with 80mm piping providing enough flow to efficiently support 500+ HP, giving plenty of headroom for tuning and future upgrades.

Each CorkSport downpipe is produced using high-quality materials and manufacturing processes. At the turbo, a cast 304 stainless steel bellmouth is used for its durability and flexibility in manufacturing. The OEM piping is replaced by 80mm mandrel bent and TIG welded piping, again for long-lasting durability. The sections are joined together using CNC machined v-band flanges for a leak-free seal.

Hardware and Accessories:

We provide all the necessary hardware to install your new downpipe, and then some. The OEM Turbo Studs are extremely long and prone to breaking, so we provide you with brand-new high-strength studs and crimp nuts. We also provide you with all-new hardware and a Remflex Gasket for the downpipe connection to the midpipe. The supplied V-band clamp ensures a secure connection between the top and bottom halves of the downpipe while providing an easier installation process. A custom heat shield is even included to protect surrounding engine bay components.

Product Advisory Note
  • Off road/motorsport use only
  • A check engine light (CEL) may be illuminated on your vehicle as a result of installation.
  • Ensure car is completely cool before working on the exhaust system to prevent injury
  • An ECU tune is recommended after installation to take full advantage of the high flow of the downpipe. While the car will operate without damage, you may experience some surging or “hiccups”, especially at wide-open throttle. This is simply the car hitting airflow & torque limits in the ECU and pulling power back.
  • Note: We are actively working on a new version that will eliminate the CEL and plan to have that available in the future once we have completed further testing and validation.

Additional Features

  • Vehicle Fitment: 2021+ Mazda3 & CX30 Turbo, 2022+ CX50 Turbo, running stock, CS 63.5mm, or CS 80mm Cat Back Exhaust.
  • Developed in America: Designed, tested, and validated in Vancouver, Washington, in the Pacific Northwest.
  • CorkSport Service and Support: Receive a 2-year warranty, full-color installation instructions, all of the needed installation hardware, and knowledgeable telephone installation support.

100 percent a must buy if you want to make power on the platform. Parts are amazing quality and look amazing. Instructions were amazing with the step by step including pictures!
Definitely worth the money if you want to make not only power but the factory downpipe definitely restrict flow for the turbo to spool up. The throttle response is night and day.
