You get a deeper,  sporty-sounding exhaust without turning your car into a raspy megaphone. We run Q300 systems on our own cars because they hit the sweet spot for a daily, clean tone on the highway, then you roll into VTEC and it actually sounds like a performance part.\u003c\/p\u003e\n\n\u003cp\u003eInvidia uses SUS304 polished stainless steel piping with mandrel bends, plus CNC machined flanges and robot TIG welding. That matters because a mandrel bent exhaust keeps the diameter consistent through the bends, so flow stays predictable and you do not choke it off where the piping turns. The Q300 also uses a flat bottom muffler, so you get a little more clearance and less turbulence under the car at speed. \u003c\/p\u003e\n\n\n\n\n\u003cp\u003e\n\u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003eVariants\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU: NVD-HS06HC2G3S\u003c\/strong\u003e | \u003cstrong\u003eBody Style: Coupe\u003c\/strong\u003e | \u003cstrong\u003eTip: Polished Stainless\u003c\/strong\u003e, this is the Invidia Q300 Civic Si coupe setup if you want the classic Invidia Q300 polished tip Civic look.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU: NVD-HS06HC2G3T\u003c\/strong\u003e | \u003cstrong\u003eBody Style: Coupe\u003c\/strong\u003e | \u003cstrong\u003eTip: Titanium\u003c\/strong\u003e, same Civic Si coupe exhaust Q300 fitment, with the darker, burnt style Invidia Q300 titanium tip Civic finish.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU: NVD-HS06HC4G3S\u003c\/strong\u003e | \u003cstrong\u003eBody Style: Sedan\u003c\/strong\u003e | \u003cstrong\u003eTip: Polished Stainless\u003c\/strong\u003e, a true Invidia Q300 Civic Si sedan option, also commonly searched as Civic Si sedan exhaust Invidia or Civic Si Q300 polished exhaust.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU: NVD-HS06HC4G3T\u003c\/strong\u003e | \u003cstrong\u003eBody Style: Sedan\u003c\/strong\u003e | \u003cstrong\u003eTip: Titanium\u003c\/strong\u003e, your Civic Si Q300 titanium exhaust option if you want the sedan fitment with a louder looking, not louder sounding tip.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cbr\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\n\n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003cp\u003e\u003cspan class=\"tag\"\u003e2006-2011 Honda Civic Si\u003c\/span\u003e\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003e\u003cspan class=\"tag\"\u003e2006-2011 Honda Civic \u003c\/span\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":"Invidia","offers":[{"title":"Coupe \/ Polished Stainless","offer_id":69040367501346,"sku":"NVD-HS06HC2G3S","price":875.83,"currency_code":"USD","in_stock":false},{"title":"Coupe \/ Titanium","offer_id":69040367534114,"sku":"NVD-HS06HC2G3T","price":938.45,"currency_code":"USD","in_stock":false},{"title":"Sedan \/ Polished Stainless","offer_id":69040367566882,"sku":"NVD-HS06HC4G3S","price":875.83,"currency_code":"USD","in_stock":false},{"title":"Sedan \/ Titanium","offer_id":69040367599650,"sku":"NVD-HS06HC4G3T","price":938.45,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/invidia-q300-cat-back-exhaust_i1jp.jpg?v=1792595941","url":"https:\/\/www.hybrid-racing.com\/products\/invidia-q300-cat-back-exhaust-for-civic-si-coupesedan","provider":"Hybrid Racing","version":"1.0","type":"link"}
