The design philosophy is straightforward: get exhaust gases out with as few restrictions and as few unnecessary bends as possible. On a naturally aspirated Honda, that shows up as better mid and high rpm breathing, and it comes with the tone HKS built its name on.\u003c\/p\u003e\n\n\u003ch4\u003eTwo Versions, Pick Your Body Style\u003c\/h4\u003e\n\n\u003cp\u003eCheck this before you order, because the hatchback and the Si coupe take different systems.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e3203-EX019\u003c\/strong\u003e fits the 1996-2000 Civic hatchback in CX and DX trim.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e3203-EX014\u003c\/strong\u003e fits the 1999-2000 Civic Si coupe (EM1).\u003c\/p\u003e\n\n\u003cp\u003eThey aren't interchangeable, so confirm what you've got. Both are Hi-Power systems built the same way with the same piping and tip sizing, just routed for different cars.\u003c\/p\u003e\n\n\u003ch4\u003eStraight Path, Fewer Bends\u003c\/h4\u003e\n\n\u003cp\u003eThis is the core of the Hi-Power design and it's borrowed directly from HKS's endurance and GT racing work in Japan.\u003c\/p\u003e\n\n\u003cp\u003eEvery bend in an exhaust is a restriction. Gas has to change direction, which slows it down and creates turbulence, and turbulent flow moves through a pipe considerably worse than smooth flow does. HKS designs these to minimize direction changes and keep the path as direct as the chassis allows.\u003c\/p\u003e\n\n\u003cp\u003eOn a naturally aspirated engine, the benefit builds as you add other modifications. A stock car doesn't produce enough exhaust volume to fully use a free-flowing system, but as you add intake, cams, or a header, the exhaust becomes the bottleneck and flow capacity starts mattering. That's why the Hi-Power tends to be the exhaust people keep as their build progresses rather than outgrowing.\u003c\/p\u003e\n\n\u003ch4\u003eSized For The Engine, Not For Show\u003c\/h4\u003e\n\n\u003cp\u003eBoth systems run 55mm piping into a 95mm outside diameter tip, and that sizing is deliberate rather than incidental.\u003c\/p\u003e\n\n\u003cp\u003eBigger isn't automatically better on exhaust. Oversize the piping on a small naturally aspirated engine and you lose exhaust gas velocity, which costs you the scavenging that pulls spent gas out of the cylinder. What you end up with is a car that might show a marginally higher peak number and feels worse everywhere you actually drive.\u003c\/p\u003e\n\n\u003cp\u003eHKS sizes these to keep velocity up where these engines live while still flowing considerably better than the restrictive factory system. It's the right size for the car rather than the biggest pipe that fits.\u003c\/p\u003e\n\n\u003ch4\u003eSUS304 Stainless Throughout\u003c\/h4\u003e\n\n\u003cp\u003eBoth the muffler and the tip are SUS304 stainless steel, which is the practical reason these last. Stainless resists rust far better than mild steel, so this isn't an exhaust that rots out after a few winters of road salt.\u003c\/p\u003e\n\n\u003cp\u003eOn a car that's now twenty-five to thirty years old, that matters. A stainless system fitted today will almost certainly outlast whatever else you're doing to the car.\u003c\/p\u003e\n\n\u003ch4\u003eThe Hi-Power Sound\u003c\/h4\u003e\n\n\u003cp\u003eWorth setting expectations honestly. The Hi-Power is a well-known tone in the Honda world and it's not a quiet exhaust. That's the point, and it's why people buy them.\u003c\/p\u003e\n\n\u003cp\u003eWhat separates it from cheap alternatives is quality of sound rather than just volume. It's a deeper, cleaner note rather than the raspy drone that comes with a poorly designed system. If you've heard one on an EK before, you know exactly what you're getting.\u003c\/p\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\n\u003cp\u003e1996-2000 Honda Civic hatchback, CX and DX (3203-EX019)\u003cbr\u003e1999-2000 Honda Civic Si coupe, EM1 (3203-EX014)\u003c\/p\u003e\n\n\u003cp\u003eSelect your application at checkout.\u003c\/p\u003e\n\n\u003ch4\u003eWho Should Run This Exhaust\u003c\/h4\u003e\n\n\u003cp\u003eThis is for the EK owner who wants a genuine name-brand exhaust rather than a generic one, and who's building the car in a direction where flow will eventually matter.
