FAQ
Is 430 stainless good for exhaust clamps?Yes. 430 stainless offers solid corrosion resistance and bright appearance at a lower cost than 304. For most street/truck use, 430 is a great value.
Will this 4" clamp fit my Diamond Eye 4" system?
If your system uses 4" tubing with a standard slip or preformed joint, this clamp is an appropriate replacement or upgrade.
Can I reuse a Torca band clamp?
Generally yes, provided the band and hardware are undamaged. Always inspect threads and band integrity before reassembly.
Do I need sealant with this clamp?
No sealant is typically required when the tubing is clean, round, and correctly overlapped. The preformed band provides even sealing pressure.
