Overview

These Milltek Sport parts fit the 2014-2020 BMW i8 coupe and roadster with the 1.5 liter turbo three-cylinder hybrid. This large-bore downpipe with a hi-flow sports catalyst frees up the i8 turbo three while keeping a catalytic converter in place. A Milltek hot-side part replaces the restrictive factory section with larger, smoother T304L tubing, so exhaust gas leaves the engine with less resistance. The BMW i8 parts are T304L stainless steel with mandrel-bent tubing, which keeps the pipe at full size through each bend and resists corrosion for years. They bolt in place of the factory parts with no cutting or welding.

How to Choose

This page has one version: the Catted Hi-Flow Sports Cat Downpipe, which keeps a high-flow sports catalytic converter. Milltek recommends an ECU remap with it.

Pair them with the Milltek cat-back for the BMW i8 for a complete Milltek exhaust.
