Do I need new gaskets or exhaust clamps to install this?

Exhaust gaskets at the manifold flange and rear connection points are not included — source gaskets and hardware separately to match your current system. Most installs require standard exhaust clamps or bolts already in your toolkit.

Will this work with an aftermarket exhaust or does it need to stay OEM?

This converter is designed around factory exhaust pipe diameters and mounting points. If your exhaust system has been modified or fitted with non-standard piping, verify inlet and outlet dimensions match before ordering.

What's the return window if this doesn't fit my system?

Check the return policy on your order confirmation. Once installed, catalytic converters cannot be returned due to emissions regulations — test-fit all connections before tightening everything down.
