Within the exhaust system, this assembly replaces the factory rear muffler and tailpipe section to change muffler construction, outlet configuration, and downstream piping dimensions while retaining the factory catalytic converter and upstream emissions hardware.\u003c\/p\u003e\n\n\u003cp\u003eOn the FK7, the factory rear muffler is designed primarily for low noise and broad fitment across trims. The SPEC L2 addresses packaging and mass targets by using a lighter muffler design and a dual outlet layout with defined tip sizing. This part is intended for installers who want a known fit cat back rear section built around documented tube diameters and documented exterior sound measurements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Honda Civic Hatchback FK7 only, L15B\/C engine, model years 2016 through 2021\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem position\u003c\/strong\u003e: Rear section cat back style exhaust, replaces the rear muffler and tail section\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction material\u003c\/strong\u003e: SUS304 stainless steel main construction\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMain pipe diameter\u003c\/strong\u003e: 60.5 millimeter inlet stepping to dual 50.8 millimeter outlets\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip diameter\u003c\/strong\u003e: Dual 94 millimeter outlets\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSound level, stationary proximity measurement\u003c\/strong\u003e: 93 decibel HKS value, 83 decibel stock value\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.4 kilogram HKS value, 5.9 kilogram stock value\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSelection and tradeoffs\u003c\/strong\u003e: Choose this part when the goal is a defined dual outlet layout and documented tube sizing, with a verified reduction in rear section weight versus stock. The published stationary sound level indicates a higher exhaust sound level than the factory system, which is a practical consideration for noise sensitivity and local enforcement. This product is specified for FK7 Hatchback fitment; it is not listed as a universal Civic fit and should be treated as chassis specific.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eInstallation scope and considerations\u003c\/strong\u003e: This is a bolt on rear section replacement that interfaces at the factory exhaust joint. Standard exhaust service steps apply, including inspection of sealing surfaces and correct gasket use where specified by the kit. No alignment changes are created by the exhaust itself, but installers should verify clearance to rear suspension components and rear bumper openings after installation due to the dual outlet tip configuration.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003cp\u003e\u003cspan class=\"tag\"\u003e2016-2021 Honda Civic Hatchback\u003c\/span\u003e\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003e\u003cspan class=\"tag\"\u003e \u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cbr\u003e \n\u003c\/li\u003e\n\n\n\n\n\u003cli id=\"TechnicalData\"\u003e\n\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\u003cli id=\"InstallGuide\"\u003e\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n","brand":"HKS","offers":[{"title":"Default Title","offer_id":69575054196770,"sku":"HKS-31019-AH108","price":1820.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/19681795.png?v=1793634744","url":"https:\/\/www.hybrid-racing.com\/products\/hks-hi-power-spec-l2-exhaust-for-17-21-honda-civic-hatchback","provider":"Hybrid Racing","version":"1.0","type":"link"}
