Product Description
This isn’t just an exhaust system—it’s an evolution in sound, style, and performance. The LEGAMAX Sports RX was crafted to give drivers the best of both worlds: a refined exhaust tone at idle and cruising speeds that won’t overpower your cabin, and a raw, dry, motorsport-inspired bark once you bury the throttle.
With a quad-tip design and rear diffuser garnishes included, your ride instantly levels up in looks. But it’s not just about aesthetics—the dual 80mm tips and efficient 60→50mm center piping significantly reduce backpressure while improving overall exhaust velocity. That means better throttle response, broader torque curves, and real-world horsepower gains—whether you’re stock or tuning your way to 350HP.
Inside the car, it’s whisper-quiet when you want it to be. Outside? It’s a different story—aggressive, sharp, and addictively sporty, thanks to HKS’ meticulous frequency tuning. And with SUS304 stainless steel construction, this system is built to take abuse and still shine through.
