Will this bolt straight to my factory cat?

Yes. This mounts at the factory catalytic converter exit and uses existing frame hangers. No modifications to the cat or mid-pipe needed.

Do I need to do any prep work before installation?

Inspect the connection point at the cat for debris or corrosion, then clean if needed. The stainless steel itself arrives ready to bolt on.

What if the hangers don't line up exactly?

Factory hanger mounts are designed to accept this system. Test-fit it in place before tightening everything down. If gaps appear, contact support with photos for hanger guidance.
