Will this bolt directly to my stock exhaust manifold and piping?

Yes. This converter is designed to mount at factory connection points with no modifications required. You'll need basic hand tools and jack stands for removal and installation of the original unit.

Do I need to replace gaskets or seals when I install this?

Factory gaskets at the manifold and downstream connection should be replaced during installation to prevent exhaust leaks. Pick up new gaskets when you source your converter — they're wear items.

What if this doesn't fit after I remove the old one?

Test-fit before fully tightening everything. This is a factory-spec replacement, but verify clearance at the exhaust heat shield and suspension components. If fitment is off, contact support with photos before permanent installation.
