Does this bolt directly to my factory cat or do I need an adapter?

This is a catback system, meaning it connects to the catalytic converter that's already on your vehicle. It bolts directly to the factory mounting points — no adapter needed.

Will this system require any modification to my current exhaust?

Not if your cat is in factory condition. The catback bolts on as-is. If you've made modifications upstream, test-fit before finalizing installation to confirm alignment.

What do I need to install this myself?

Basic hand tools are all you need — jack, jack stands, and standard wrenches. Refer to your vehicle's service manual for torque specs on the mounting bolts.
