Want a car that sounds like an American muscle car should? This header will help your vehicle achieve that and it can add up to 8-20 horsepower. Install an exhaust system means about a 0.5 mpg gas mileage improvement. While that might not sound like much, consider this: If gas costs $3 a gallon and drive this truck 15,000 miles a year, you’re saving yourself about $85 a year on gas. In five years, you’ll have saved nearly enough money to pay for a complete cat-back exhaust system.\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Predator Performance®","offers":[{"title":"Default Title","offer_id":42358815293534,"sku":"FLES08368","price":113.44,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0030\/5315\/8515\/files\/Screenshot_2026-04-16_at_5.38.39_PM.png?v=1776386412","url":"https:\/\/10secondracing.com\/en-gb\/products\/06-09-honda-civic-si-2-0l-k20z3-fg2-fa5-exhaust-manifold","provider":"10 Second Racing","version":"1.0","type":"link"}
