Frequently Asked Questions
Do I need gaskets or new bolts to install this?
Have new gaskets and exhaust bolts on hand before you start. The converter bolts into factory flanges—reusing old hardware or gaskets often leads to leaks. Pick up OEM gasket sets and stainless bolts while you're at it.
Will my check engine light clear once I bolt this on?
The light may stay on until the system resets. After installation, drive normally for 50–100 miles so the oxygen sensors recalibrate. If the light doesn't clear after that, scan the code to confirm it's converter-related and not a sensor issue.
What's your return policy if it doesn't fit?
Test-fit the unit against your old converter before you remove it from the box. Check that flanges align and bolt holes match up. If there's a mismatch, contact support with photos—returns are handled case by case within 30 days of purchase.
