APEXi N1-X Evolution Extreme Exhaust Systems

APEXi N1-X 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. Most of the tips are constructed with a lightweight titanium material rolled and riveted onto a double pipe structure; this acts as a diffuser enabling temperature reduction, while retaining a sporty heat gradiation appearance. Many options are available, including system style (cat-back, rear axle-back, etc.), exit location, pipe diameter, muffler quantity, inlet/outlets, tip size, and more. Order the model recommended for your vehicle. Additional details: * N1-X Evolution Extreme titanium tips are specially designed with clearance to reduce heat transfer * Top-level quality using full TIG-welded SUS304 stainless steel * Matched and manufactured for select chassis * APEXi intricate designed brackets * Resonated mid-pipe structure * Comfort with optimal performance gains

APEXi Aluminum Induction Boxes

APEXi aluminum induction boxes effectively shield the intake filter element from power-robbing heat caused by turbocharged engines and extreme underhood conditions. By fully enclosing the filter element and directing the intake air charge away from the heat-soaked engine components, the APEXi induction boxes help prevent the ingestion of hot, preheated air from within the engine compartment. This reduction of intake air temperature promotes more efficient combustion, which in turn creates better performance and increased reliability. All components are manufactured by APEXi to the highest standards to ensure precise fitment and maximum performance.
