Invidia 15+ Subaru WRX/STI Single N1 Stainless Steel Tip Cat-back Exhaust

This Invidia exhaust is built for real gains you can feel in the seat. Smooth bends and smart muffler design improve flow and throttle response while keeping the note tight and controlled. N1 is the classic motorsport look and sound with a freer flowing path and a sharper note when you get on it. The single-exit layout trims weight and simplifies flow for fast spool and strong midrange. This setup pairs well with the Wrx platform and responds nicely to basic bolt-ons and a clean tune. Quality materials and precision welding help resist heat and corrosion. The result is consistent fitment, solid hardware, and a system that performs without constant attention. Expect better response off the line, stronger pull through the midrange, and a tone that feels right for a quick street car. Bolt-on installation with standard tools in most cases.
