Do I need new gaskets or hardware to install this?

New gaskets at the inlet and outlet flanges are always a good idea to avoid leaks. Hardware (bolts and clamps) are not included — pull your old converter first and reuse existing fasteners if they're in good shape, or grab replacements from the hardware section.

Will this pass emissions testing?

Yes. This converter is engineered to meet federal emissions standards and will work with your vehicle's OBD system. If you're due for a smog check, this gets you compliant.

Can I install this myself?

Absolutely. It's a bolt-on swap at the factory mounting points — you'll need jack stands, basic wrenches, and a little patience for tight access. Plan 30–60 minutes depending on how stuck the old bolts are. Work on a cool engine.
