The W213 E63's factory downpipe carries a restrictive section that limits exhaust flow from the M178 twin-turbo V8. This mirror polished stainless steel downpipe replaces it with a high-flow design, improving turbo response and exhaust flow.
Why Upgrade?
- High-flow design significantly less restrictive than the factory downpipe
- Improved turbo response and exhaust flow from the M178 V8
- Mirror polished 304 stainless steel construction
- Direct OEM replacement installation
Built for the Drive, Not Just the Dyno
The M178's twin-turbo V8 has real presence once the factory downpipe restriction is dealt with — this kit clears it on both banks at once, with a mirror finish that looks the part under the bonnet as much as it performs.
