Will these clamps work with my custom exhaust piping?

These are sized for 2.0" diameter tubing. Measure your pipe OD to confirm fit—they won't clamp properly if the diameter is significantly larger or smaller.

Do I need bolts or fasteners to install these?

The clamp assembly includes all necessary hardware—just position around your tubing and tighten the band mechanism.

How often will I need to retighten them?

Exhaust systems expand and contract with heat cycles. Check clamp tension after your first drive, then periodically during regular maintenance to ensure they stay secure.
