Overview

This precision-made system specifically delivers increased power, particularly in the low and mid rev ranges. It also significantly enhances the exhaust note, providing a deep, resonant, and sporty sound while neutralizing annoying frequencies in critical RPM ranges.

Show original supplier description

Beyond the performance enhancements, it dramatically alters the exhaust note, introducing a deep, sporty, and resonant sound while effectively mitigating undesirable frequencies. This precision-made performance system includes a ceramic-coated race downpipe. The construction prioritizes both performance and longevity, with the ceramic coating contributing to heat management and durability. This downpipe is compatible with a range of BMW models from 2017 onwards. Specifically, it fits the BMW 340i/440i (Chassis F30/F31), BMW 540i (Chassis G30/G31), BMW M140i (Chassis F20/F21), and BMW M240i Coupe (Chassis F22).

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.

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.
