APEXi N1 Evolution Extreme Exhaust Systems
APEXi N1 Evolution Extreme Exhaust Systems are based on the proven performance basics of the N1 muffler—which emphasizes optimum exhaust efficiency utilizing a straight-thru layout design. They are equipped with an internal hybrid silencer uniting power and free-flowing characteristics with effective functional sound resonance. A newly adopted muffler tip completes the tail-end of the exhaust that serves both purposes of function and form. Many options are available, including muffler quantity, inlet/outlet quantity, and tip material/shape/size. Order the system recommended for your vehicle.
Additional details:
* High level of quality using TIG-welded SUS304 stainless steel, uniting quiet performance with high-power performance gains
* Matched and manufactured for select chassis
* Patented Megaphone piping structure to produce excellent torque and throttle response throughout the powerband. This piping design allows for a swirling exhaust gas flow effect that has for years produced proven results
