Valvetronic Designs' new EPA-compliant 400 cell high-flow catted downpipe for the B58 turbocharged inline-6, offered for Gen 1 / Gen 2 engines and the latest Gen 3 (B58N). Whatever the generation, the factory catalyst holds back exhaust flow and turbo efficiency; this downpipe lowers backpressure, improves spool and gives a deeper, more aggressive tone, on stock or tuned cars, while keeping a catalyst in place.

Features

  • EPA-compliant 400 cell high-flow catalyst: better exhaust efficiency while keeping a catalytic converter in place
  • Quicker turbo spool: less restriction for sharper response and more mid-range torque
  • More tuning headroom: supports higher boost than the restrictive factory catalyst
  • Deeper tone with stronger turbo sounds and sharper crackles
  • With the stock exhaust: more depth and turbo presence and better exhaust clarity
  • With a Valvetronic exhaust: the biggest change, with more crackles, sharper turbo spool sound and a more aggressive overall character
  • Designed to pair with Valvetronic Designs exhaust systems

Specifications

  • Engine: BMW B58 turbocharged inline-6 (Gen 1 / Gen 2 or Gen 3 B58N, select when ordering)
  • Catalyst: 400 cell high-flow, high-temperature resistant core, EPA compliant
  • Construction: high-grade stainless steel, precision TIG-welded
  • Tubing: mandrel-bent for smooth internal transitions and maximum exhaust velocity
  • Flow layout optimised to cut backpressure while keeping catalyst efficiency
  • OEM-style O2 sensor placement for correct sensor operation
  • Built for long-term reliability under high boost and tuned use
