Please ensure your correct model is selected

When BMW began to offer more and more forced induction vehicles, some enthusiasts were upset and others were excited about the big power potential. While we love older, naturally aspirated BMWs, we LOVE forced induction BMWs. Upgrading your downpipe (or downpipes) is one of the easiest ways to reduce restriction and add more power to your BMW. We offer several brands, including our own designs, of downpipes for your BMW!

CTS Turbo High Flow-CATS are made to maximize exhaust flow for the highest power gains. Designed using the latest in CAD technology; this part is made to fit perfectly in place of the restrictive factory catalytic converter. Manufactured from CAST T304 stainless steel; hand TIG welded and back-purged to ensure years of reliable performance. In addition to unleashing the power and performance of your 3.0 Twin Turbo, CTS' High Flow-CATS will make your vehicle sound like it really should. When installed with factory exhaust, it produces a louder and deeper growl with a much more pronounced exhaust “crackle” on downshift. While up-shifting you will enjoy a confident “punch!” as you bang through all 8 gears. The sound will be even louder if you already have an aftermarket exhaust system. Product Details: Designed and tested on a real car in the real world Cast T304 stainless steel, TIG welded back-purged construction 200 Cell High Flow-CATS Great power upgrade with uncompromising performance Incredible sporty exhaust sound, subtle when cruising No drone with factory exhaust Fitment: 2019-2022 G01 BMW X3M 2019-2022 G01 BMW X3M Competition 2019-2022 G02 BMW X4M 2019-2022 G02 BMW X4M Competition To remove the CEL that will occur, proper stage 2 tuning software must be used.
