S58 Engine 200 CEL Catted Downpipes-Thermal Coated Black Finish (BM-EXH028TBCAT)

Upgrade your 2021+ BMW M3/M4 or 2023+ BMW M2 with the Evolution Racewerks Sports Series High Flow Catted Downpipes. Engineered to optimize exhaust flow, these downpipes feature a 200-cell metallic catalytic converter that increases horsepower and torque while reducing turbocharger lag. By replacing the restrictive factory catalytic converter, the Sports Series downpipes ensure faster turbo spool-up, better throttle response, and more power overall. Crafted from 100% 304-grade stainless steel with TIG-welded seams, these downpipes provide track-tested durability and a seamless fit with both factory and aftermarket exhaust systems.

The Sports Series High Flow Catted Downpipes utilize a 200-cell metallic core, allowing exhaust gases to pass through more freely compared to the factory's ceramic catalytic converter. The lower cell count and larger individual cells reduce backpressure, improving performance while also being more durable and heat-resistant than ceramic options. With precise CNC machining and stainless steel construction, these downpipes are built to last and handle extreme conditions on and off the track.

Fitment:

• 2021+ BMW M3 (S58 engine)
• 2021+ BMW M4 (S58 engine)
• 2023+ BMW M2 (S58 engine)
