The Hi-Power design does that by minimizing bends and giving gases the straightest path out, which on an engine spinning to 9,000 rpm is exactly where the gains are. Two configurations available: a dual exit built for naturally aspirated cars and a single exit racing system designed for turbo applications.\u003c\/p\u003e\n\n\u003ch4\u003eDual Exit Or Single Exit?\u003c\/h4\u003e\n\n\u003cp\u003eThese are genuinely different systems for different cars, not two styling options.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDual exit\u003c\/strong\u003e is the naturally aspirated system. Twin 94mm polished tips fed by dual 60-50mm center pipes, built from S409 stainless. This is the one for a stock or bolt-on S2000.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSingle exit\u003c\/strong\u003e is a racing muffler built for turbo applications. A single 74.7mm pipe into a 97mm adjustable-length titanium tip, made from S304 stainless.\u003c\/p\u003e\n\n\u003ch4\u003eWhy The Single Exit Uses One Big Pipe\u003c\/h4\u003e\n\n\u003cp\u003eWorth understanding, because the difference isn't cosmetic.\u003c\/p\u003e\n\n\u003cp\u003eA naturally aspirated F20C produces a manageable volume of exhaust gas, and dual smaller pipes suit it. You keep gas velocity up, which drives the scavenging that pulls spent gas out of the cylinder, and you get the balanced dual-exit look the S2000 wears well.\u003c\/p\u003e\n\n\u003cp\u003eAdd a turbo and the math changes completely. Exhaust volume climbs dramatically and the restriction moves. A single 74.7mm pipe gives that volume somewhere to go, which helps spool and top-end power. On a naturally aspirated car that same pipe would cost you velocity and midrange for nothing.\u003c\/p\u003e\n\n\u003cp\u003eSo buy the single exit if you're boosted. Buy the dual exit if you're not.\u003c\/p\u003e\n\n\u003ch4\u003eThe Titanium Tip Is Adjustable\u003c\/h4\u003e\n\n\u003cp\u003eA nice detail on the single exit system. The 97mm titanium tip is adjustable for length, so you can dial in exactly how far it sits relative to the bumper rather than accepting whatever the fabrication gave you.\u003c\/p\u003e\n\n\u003cp\u003eThe titanium gradient finish is the other half of it, and it's immediately recognizable on a car built seriously. The dual exit uses polished stainless tips instead, which suits the cleaner street look.\u003c\/p\u003e\n\n\u003ch4\u003eQuieter Than You'd Expect\u003c\/h4\u003e\n\n\u003cp\u003eHere's a number worth knowing. HKS measures the dual exit system at 95dB closed, and a stock S2000 measures 95dB. Same figure.\u003c\/p\u003e\n\n\u003cp\u003eThat doesn't mean it sounds identical, because tone changes considerably and you'll hear the difference immediately. But it does mean the Hi-Power isn't buying its flow by simply being louder, which is what a lot of cheaper systems do. You get better breathing without the car becoming a problem in your neighborhood.\u003c\/p\u003e\n\n\u003ch4\u003eStraight Path, Fewer Bends\u003c\/h4\u003e\n\n\u003cp\u003eThe core of the Hi-Power design, taken directly from HKS's endurance and GT racing work in Japan.\u003c\/p\u003e\n\n\u003cp\u003eEvery bend is a restriction. Gas has to change direction, which slows it and creates turbulence, and turbulent flow moves through a pipe considerably worse than smooth flow. HKS lays these out with gentle bends and direct pathways to minimize that.\u003c\/p\u003e\n\n\u003cp\u003eOn an engine that revs to 9,000, the top of the range is where a restrictive exhaust costs you most, and it's where you'll notice this most.\u003c\/p\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\n\u003cp\u003e2000-2009 Honda S2000, including CR\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDual exit:\u003c\/strong\u003e naturally aspirated application, S409 stainless, twin 94mm polished tips, 60-50mm dual center pipes\u003cbr\u003e\n\u003cstrong\u003eSingle exit:\u003c\/strong\u003e turbo application, S304 stainless racing muffler, 97mm adjustable titanium tip, 74.7mm center pipe\u003c\/p\u003e\n\n\u003ch4\u003eWho Should Run This Exhaust\u003c\/h4\u003e\n\n\u003cp\u003eThis is for the S2000 owner who wants a genuine HKS system rather than a generic cat-back. If the car is naturally aspirated, the dual exit gives you better flow, the Hi-Power tone, and a finish that suits the car. If you've gone turbo, the single exit is built for exactly that. Pick based on what your car actually is, and go use the revs.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e 2000-2009 Honda S2000, including CR. \u003cstrong\u003eType:\u003c\/strong\u003e cat-back exhaust system. \u003cstrong\u003eDual exit:\u003c\/strong\u003e S409 stainless, 94mm polished tips (left and right), 60-50mm dual center pipes, 95dB closed. \u003cstrong\u003eSingle exit:\u003c\/strong\u003e S304 stainless racing muffler, 97mm adjustable-length titanium tip, 74.7mm center pipe, 95.5dB closed.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003cp\u003e\u003cspan class=\"tag\"\u003e2000-2005 Honda S2000\u003cbr\u003e\u003c\/span\u003e\u003cspan class=\"tag\"\u003e2006-2009 Honda S2000 \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":"HKS","offers":[{"title":"Dual Exit","offer_id":46609585569826,"sku":"HKS-32003-AH007","price":1560.0,"currency_code":"USD","in_stock":false},{"title":"Single Exit (Passenger Side)","offer_id":46609585602594,"sku":"HKS-32701-BH001","price":1100.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/55d4222c8c40f60b8b26042952fdd08f.jpg?v=1787848326","url":"https:\/\/www.hybrid-racing.com\/products\/hks-hi-power-catback-exhaust-00-09-s2000","provider":"Hybrid Racing","version":"1.0","type":"link"}
