Will I need to modify my exhaust hangers or heat shields?

Test-fit before final installation. Factory hangers may require adjustment or repositioning to match the new exhaust geometry. Measure clearance to the fuel tank and underbody panels after dry-fitting.

Do I need to replace the O2 sensor or tune the engine?

This is a bolt-on catback — no O2 sensor work required. Your vehicle will run as-is, though some owners tune for optimal results. Consult your tuner or service manual for recommendations.

What's the return window if it doesn't fit?

Confirm your vehicle details and fitment before purchase. If there's a fitment concern, contact support with photos of your setup for guidance before installation.
