Will this fit my current muffler?

It slides over any 3.0" diameter muffler outlet. Measure your existing outlet first to confirm the fit — if it's larger or smaller, this won't work without an adapter.

Do I need fasteners or clamps to install this?

You'll need hose clamps or band clamps to secure it to the outlet. The tip itself doesn't come with mounting hardware — grab stainless steel clamps to match the finish and keep everything tight.

How do I keep the polish looking new?

Stainless steel polished tips hold their shine longer than painted options, but exhaust heat and road salt will dull them over time. Occasional wash with a microfiber cloth keeps it looking fresh — no special coating needed.
