APEXi | Innovative Performance Parts for Cars, Exhaust Systems, & Tuning Solutions

APEXi, founded in Japan in 1992, has become a globally recognized leader in high-performance automotive tuning parts, providing enthusiasts with cutting-edge solutions for enhancing engine performance and exhaust systems. Over the years, APEXi has established itself as a pioneer in the aftermarket automotive parts industry, offering products known for their precision engineering, durability, and innovation.

One of APEXi’s standout products is the Active Tail Silencer (ATS), designed to provide a dynamic solution for exhaust sound management. Traditional tail silencers restrict power under high load, sacrificing performance for quieter operation. The ATS features a pressure-activated valve that adjusts automatically: keeping sound levels low during low load and allowing for straight-through power under high load. The ATS comes in two sizes—115mm and 90mm—making it a versatile addition to various exhaust systems. The best part? You don’t need to swap your entire exhaust system, as the ATS works with any APEXi muffler, turning your exhaust into a variable sound system that delivers both performance and quiet operation.

With a focus on cutting-edge engineering and customer feedback, APEXi has become a trusted name for tuning enthusiasts around the world. From exhaust systems, performance mufflers, fuel management, to turbochargers, APEXi’s comprehensive product lineup offers solutions for every aspect of tuning your vehicle to perfection.
