The deciding check
Borla specifically excludes cars whose original exhaust includes valves. The model badge and engine size do not settle this requirement. Record the factory exhaust configuration before ordering, and have Borla or the installer resolve uncertainty.

What the package provides

Plan the correct installation
If the original exhaust has valves, Borla directs buyers toward an appropriate system with valves or valve simulators. Do not treat deleting an electrical connection as a documented conversion. Save the exact product listing and download its installation sheet before scheduling. This is a compatibility decision guide; under-car removal, fastening and alignment follow the matched installation instructions.
