Will this bolt directly onto my existing exhaust without cutting or welding?

Yes — this converter uses factory mounting points and flanges. Installation is a straight swap at the bolted connections. No cutting, welding, or exhaust rework required.

Does this come with gaskets or clamps?

The converter assembly ships as a single unit. You'll need gaskets and fasteners to complete the connection — source these from your vehicle's OEM parts list or a hardware supplier to match your factory specs.

What happens if I install this and my check engine light stays on?

A persistent light after install usually means a wiring or sensor issue unrelated to the converter itself. Scan the vehicle with a code reader to identify the fault. If the code clears after a few drive cycles, the system is learning the new component.
