The K24 has a voice and the factory system does everything it can to hide it. This HKS Silent Hi-Power replaces it from the cat back, opening up flow with a 60mm center pipe while keeping the volume civilized enough to daily.\u003c\/p\u003e\n\n\u003ch4\u003eSilent Hi-Power Means Exactly That\u003c\/h4\u003e\n\n\u003cp\u003eHKS makes two versions of this exhaust and the choice matters.\u003c\/p\u003e\n\n\u003cp\u003eThe standard Hi-Power is loud. That's its whole identity, and plenty of people want it.\u003c\/p\u003e\n\n\u003cp\u003eThe Silent Hi-Power gives you the same flow benefits with a Type-H round silencer that keeps cabin noise down. On a TSX, which is a refined car by design, that's usually the right call. You get a better sound and a freer exhaust without turning a comfortable sedan into something that drones on the highway.\u003c\/p\u003e\n\n\u003cp\u003eIf your TSX is still a daily driver or a long-commute car, this is the version to buy.\u003c\/p\u003e\n\n\u003ch4\u003e60mm Center Pipe\u003c\/h4\u003e\n\n\u003cp\u003eSized for the K24 rather than being the biggest pipe that fits.\u003c\/p\u003e\n\n\u003cp\u003eExhaust gas needs velocity as well as volume. Oversize the piping on a 2.4 liter naturally aspirated engine and you lose the scavenging that helps pull spent gases out, which costs you midrange for a peak number you'll rarely use.\u003c\/p\u003e\n\n\u003cp\u003e60mm flows considerably better than the restrictive factory system while keeping velocity where the K24 lives. HKS sizes these per application for exactly that reason.\u003c\/p\u003e\n\n\u003ch4\u003eSUS304 Stainless Throughout\u003c\/h4\u003e\n\n\u003cp\u003eThe whole system is SUS304 stainless steel, which is the practical reason these last.\u003c\/p\u003e\n\n\u003cp\u003eStainless resists rust far better than mild steel, so this isn't an exhaust that rots out after a few winters of road salt. On a TSX that's now fifteen to twenty years old, a system fitted today will almost certainly outlast the rest of the car.\u003c\/p\u003e\n\n\u003cp\u003eThe silver finish keeps it looking right underneath rather than going dull and rusty the way the factory system eventually does.\u003c\/p\u003e\n\n\u003ch4\u003eWhat To Expect\u003c\/h4\u003e\n\n\u003cp\u003eHonest framing, since a cat-back on a naturally aspirated engine isn't a power modification.\u003c\/p\u003e\n\n\u003cp\u003eYou'll notice the sound immediately and the throttle response slightly. What you won't notice is a dramatic power increase, because you're replacing the last section of exhaust on a 2.4 liter that Honda already engineered reasonably well.\u003c\/p\u003e\n\n\u003cp\u003eWhere it earns its keep is in tone, in construction that outlasts the factory system, and in having capacity available if you add a header or intake later. If you want the TSX to sound like the K24 it has rather than like a rental car, that's exactly what this does.\u003c\/p\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\n\u003cp\u003e2004-2008 Acura TSX (CL9)\u003c\/p\u003e\n\n\u003cp\u003eCat-back system.

HKS quality, stainless construction, and a tone that suits a sedan you actually drive rather than one you're trying to make obnoxious.
