Product Details

Description

CTS Turbo is proud to announce the release of our High-Flow CAT downpipes for BMW F80/F82 M3/M4/M2 Competition

CTS Turbos stainless steel high-flow CAT downpipes allow for faster spool, better transient boost response, higher boost, and great sound. 

The downpipes are the first part of their modular exhaust system and are compatible with factory mid-pipes and CTS Turbos' upcoming mid-pipes. 

You should expect strong torque gains when paired with appropriate tuning software. CAD simulation is used to streamline exhaust gasses and ensure seamless integration with the factory and CTS exhaust components.  Many hours of R&D were spent to ensure a perfect fit, smooth exhaust flow, and excellent sound.

Please note: 

CEL will illuminate if correct software tuning is not used.

  • Sounds great

    I was worrisome when I first purchased this downpipe for my 2017 M3 ZCP because I didn’t see any reviews or YouTube videos but I took a chance and bought it. This is definitely the best catted downpipe in the price range. It sounds awesome and turns the rasp into a rumble. I have the competition package exhaust which is titanium which also helps. I also didn't get a check engine light when it was installed. I’m running it now with an intercooler, heat exchanger, charge pipes, j pipe, 1 step colder ngk spark plugs, intakes, and a Bootmod3 stage 2 tune. I’ve had no issues and am very satisfied.
