Will this bolt directly to my stock catalytic converter?

Yes — this catback system connects at factory mounting points and bolts to your existing cat. No adapters or welding needed.

Do I need to jack up the car to install this, or can I work under there with ramps?

Either ramps or a jack works fine. You'll need basic hand tools and enough clearance to access the bolts under the vehicle. Allow a couple of hours if you're doing it for the first time.

Can I install this myself, or do I need a shop?

DIY-friendly — it's designed as a bolt-on system. If you're comfortable with hand tools and vehicle safety, you can handle it in your driveway. No welding, cutting, or specialized equipment required.
