Description

Featuring a 4-inch diameter and a 200-cell high-flow metallic catalytic converter, this downpipe is designed to increase torque, horsepower, and throttle response. It offers a cleaner emissions solution compared to cat-delete pipes. This downpipe is constructed with a sport catalytic converter and mandrel-bent piping for optimal exhaust gas velocity. It is available in various finishes, including Brushed Silver, Mirror Polished, and Black Ceramic, to complement your vehicle's aesthetic. The Evolution Racewerks Performance Downpipe is specifically designed for the following BMW fitments: 2 Series F22/F23 (2018-2021) 230i and 230xi; 3 Series F30/F31/F36 (2016-2019) 330i and 330xi; 4 Series F32/F33/F34 (2016-2020) 430i and 430xi; and 5 Series G30 (2017+) 530i and 530xi. Note: Some users have reported potential check engine lights with this downpipe, and it is recommended to use GESI or HJS catalytic converters to avoid this issue. BimmerWorld reserves the right to cancel orders for parts not intended for legitimate racing or track purposes, and may require confirmation of racing licenses or build proof. Certain shipping restrictions may apply to specific states or territories.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
