Do I need to install this myself or can a shop handle it?

Either way works. The catback bolts directly to the factory catalytic converter connection point — a shop can knock it out in under an hour, or if you've got jack stands and basic hand tools, it's a straightforward weekend DIY job.

Will this system fit with my factory catalytic converter?

Yes. This catback bolts downstream of the cat converter, so your factory cat stays in place. No modifications needed on that end.

Does this come with gaskets and hangers?

The exhaust system itself is confirmed. Verify gasket and hanger kit inclusion before checkout — you may want spares on hand depending on your vehicle's condition.
