Do I need bolts or fasteners to install this clamp?

The clamp itself uses a tightening mechanism to secure around the pipe joint. Confirm your specific installation setup matches the clamp band width and bolt pattern before purchase — lap joint clamps vary in fastening method.

Can I use this on a welded exhaust system, or does it only work for slip-fit pipes?

This clamp is designed for slip-fit or coupler-style exhaust joints where two pipe sections overlap or meet end-to-end. It won't work on fully welded seams — it's meant to secure existing pipe connections.

Will stainless steel hold up to direct muffler heat?

Stainless steel resists corrosion and oxidation in exhaust environments far better than mild steel. It won't rust from moisture or salt exposure, though extreme continuous heat cycling may eventually affect the clamp's clamping force — retightening after a few heat cycles is common practice.
