Will this bolt directly to my factory catalytic converter?

Yes. This system mounts at the OEM connection point—no adapters or modifications needed. Just unbolt the old exhaust and secure this one in place.

Do I need to remove or reprogram anything under the vehicle?

No. Since this bolts to the existing cat, your O2 sensors and emissions system remain untouched. Straight swap with basic hand tools.

What kind of maintenance does stainless steel need?

Stainless requires far less than mild steel—no painting or rust prevention treatments. Wash with the truck and it'll stay bright. No special care needed.
