T4 Divided Flange – 3/8″ Stainless Steel
When your build demands precision at the turbine inlet, do not settle for a flange that fights you. This t4 divided flange stainless steel piece is built to the spec serious fabricators want.
Features & Benefits
Divided Port Design
The divided, twin-scroll port layout preserves exhaust pulse separation all the way to the turbine wheel, helping your turbo spool faster and run more efficiently than an open T4 flange allows.
3/8″ Material Thickness
At nearly 10 mm thick, this flange holds its shape under sustained exhaust heat and cycling. The extra rigidity supports a solid, leak-free seal between your manifold and turbine housing, build after build.
Stainless Steel Construction
Stainless steel shrugs off the corrosion, road salt, and moisture that eat through mild steel flanges over a Canadian winter — or any winter. No coating required, no rust creeping toward your manifold welds.
Straightforward Fabrication-Friendly Fitment
Machined to the standard T4 bolt pattern, this flange welds cleanly onto fabricated or modified exhaust manifolds. Whether you are laying down fresh tube on a custom manifold or patching a turbo upgrade into an existing setup, this is a plug-and-play starting point for the hard work.
