Vehicle / Turbo Fitment
This clamp fits S400-series turbochargers with T6 housings and a 5" V-band outlet. Because S400 turbos are used across many engine platforms and custom builds, always verify by measuring your outlet and matching the mating flange profile.
- Measure before ordering: Confirm a true 5" V-band outlet and compatible mating flange.
- Not for: 4" outlets, non-V-band (Marmon/bolt-on) connections, or non-S400 housings.
Install Notes
- Ensure both V-band sealing faces are clean and fully seated before tightening.
- Snug the clamp evenly; then tighten gradually until the joint is secure. Do not overtighten.
- Follow the turbo/downpipe manufacturer’s torque guidance when available.
- Re-check clamp tightness after initial heat cycles.

FAQ
Will this fit my S400 turbo?
If your turbo has a T6 turbine housing with a 5" V-band exhaust outlet, this clamp is the correct style. Measure your outlet and verify the mating flange to be sure.
Is the mating flange included?
No. This listing is for the clamp only. A matching 5" V-band flange on the downpipe side is required.
Can I use this on a 4" outlet?
No. This part is specifically for 5" outlets. A different clamp is required for 4" V-band applications.
What torque should I use?
Tighten gradually until the joint is secure and fully seated. If a torque value is provided by your turbo or hardware manufacturer, follow that spec.
