Frequently Asked Questions
Do I need new gaskets or hardware to install this?
You'll want fresh gaskets at the catalytic converter connection point—reusing old ones can cause leaks. Check your vehicle service manual for the correct gasket size and any additional fasteners needed at that joint.
Will this bolt directly to my factory cat, or do I need an adapter?
This is designed for OEM-style mounting at the factory catalytic converter location. Test-fit at that connection before finalizing installation to confirm alignment with your specific vehicle.
Does stainless steel need any prep or coating before I install it?
No prep needed—304 stainless resists corrosion on its own and doesn't require painting or sealing. You can bolt it on as-is and it'll age naturally with a patina over time.
