Overview
The B9 S4/S5 EA839 3.0T factory Downpipe carries an OPF filter that is the primary restriction in the post-turbo exhaust path. Removing it with this catless Downpipe opens the exhaust circuit — improving turbo spool, exhaust flow and providing the foundation for meaningful power gains on tuned EA839 applications.
- Removes the primary restriction in the factory post-turbo exhaust path
- Improved turbo spool — the turbo recovers and builds pressure faster
- More defined exhaust tone under load
- Stainless Steel construction for longevity
Engineering Focus
Fabricated from SS304 Stainless Steel with OPF delete section. Matched to the OEM Downpipe flanges for direct replacement. No fabrication required.
Driving Experience
A catless Downpipe is the clearest sign a build has moved past stock thinking — every gram of OPF restriction gone from the EA839's V6 at once. It's a road-and-track piece for builds that have already committed to a tune, not a daily-comfort one.
