Do I need custom piping or brackets to install this?

Your inlet diameter needs to match or adapt to the outlet size. Mounting method isn't locked to factory points — you'll need to verify how it connects to your existing pipe and use appropriate hangers for your setup.

Can I paint or coat this muffler before installation?

The exterior can be painted or ceramic coated if desired. Let any finish fully cure and cool before bolting it in. The interior doesn't need prep — it's ready to handle flow as-is.

What's the return process if this doesn't fit my setup?
