Check Before Ordering
- Verify the exact model year, body style, 3.0L turbocharged engine and rear-wheel-drive configuration. The current FAQ also lists E91/E93 applications; confirm the individual vehicle before ordering.
- Compare both ends of your existing downpipe with the product and supplied hardware. The current written connection description needs confirmation against an installation drawing.
- This part has no catalytic converter. The current listing designates it for off-road, track and racing use and asks buyers to check applicable regulations.
- The current listing says a catalyst-related check engine light may appear. Confirm diagnosis and any calibration requirements with a qualified professional; do not assume a warning light will be absent.
