Product Description
Interstate-McBee M-5290118 S400 T6 5" Exhaust Outlet V-Band Clamp – Popular for 24V 5.9L Cummins Builds
Heavy-duty 5.0" V-band (Marmon) clamp designed for turbo and exhaust connections. Ideal for S400 T6 turbine outlets using a 5" downpipe and widely used across Cummins and other diesel platforms that require a 5" V-band joint. Stainless construction and OEM-style dimensions deliver a secure, leak-resistant seal.
- S400 T6 compatibility: Pairs with 5" outlet flanges common on S400/medium-frame turbos.
- Universal 5" application: Works anywhere a 5" V-band clamp is specified (turbo outlet, aftertreatment joints, etc.).
- Stainless & serviceable: Corrosion-resistant band with service-friendly fastener.
- Aftermarket value: Interstate-McBee quality at a fraction of many OEM prices.

- Other common applications: Medium-frame turbos (e.g., S400/HT60/HT3B families) and Cummins heavy-duty/aftertreatment joints that specify a 5" V-band.
Install Notes

FAQ
Will this fit my S400 T6 turbo?Yes—if your turbine outlet uses a 5" Marmon/V-band flange. Many S400 T6 housings do. Measure your flange OD (≈5.75" to 5.91") to confirm.
Is this clamp stainless?
Yes. The band is stainless to resist corrosion in high-heat exhaust environments.
Does this include the mating flange or gasket?
No—this listing is for the clamp only. V-band joints typically seal metal-to-metal when properly aligned and torqued.
Will it work on a stock 24V 5.9L Cummins?
This is a universal clamp. It’s commonly used on 24V builds running an S400 T6 turbo and a 5" downpipe. Stock hardware may use different sizes—measure before ordering.
