FAQ
Will 178498 fit my S500?
Yes—if your turbo uses the 110mm (≈109.7mm) turbine wheel. Always verify wheel OD and shaft spec before ordering.
Is this a divided or open volute housing?
Open (single-scroll) T6 volute; excellent top-end flow. For spool bias with certain manifolds, consider divided T6 housings.
What outlet does it use?
~5.16" V-band/Marmon style. Confirm your downpipe flange and clocking.
Do I need wastegate provisions?
This housing is non-gated. External gating can be added in the manifold or up-pipe as needed.
Street legal?
Race/off-road only where required. Check local and federal regulations.
