Do I need bolts or fasteners to install this clamp?

The clamp uses a tightening band mechanism — tighten the band with a wrench to create the seal. Standard wrench and basic hand tools are all you need; no additional fasteners are required.

Will this clamp work on pipes that are slightly dented or out of round?

Lap joint clamps work best on smooth, round tubing. Test-fit on your exhaust pipe first to confirm a tight seal. Minor surface imperfections usually aren't a problem, but significant dents may prevent full contact.

Can I use this on a muffler inlet, or is it only for pipe-to-pipe connections?

This clamp is designed for tubing couplers and connections. Muffler inlets vary widely by design — confirm your muffler inlet diameter matches 3.0" before purchasing.
