Frequently Asked Questions
Q: How do I know which exhaust is best for my Focus?
A: Match your year/make/model first. For most, a catalytic converter or muffler upgrade is easiest. If you want more power, look for a catback system. Check spark plugs for your Focus ST to pair with exhaust upgrades.
Q: Will a catback affect emissions?
A: Most catbacks don’t alter emissions, but always confirm with your state. EPA-compliant converters (like #641514) ensure legal status.
Q: Can I install an exhaust myself?
A: Bolt-on kits (like the A-Premium) are DIY-friendly. Complex manifolds or high-flow headers may need a pro.
Q: Which exhaust sounds the best?
A: Sporty catbacks (like PM PERFORMOTOR’s 4.5″) offer aggressive tones. Mufflers like Walker 50079 are quieter.
Q: Do exhaust upgrades void warranties?
A: Some manufacturers may deny claims for major mods, but simple converters usually aren’t an issue. Always review warranty terms.
