Optimum gas flow and minimal exhaust back pressure is essential for high power. The APS high output stainless steel exhaust system really performs.

Crafted in premium 304 stainless steel and precision TIG welded, the APS system is designed to perform at the most extreme power levels. Careful attention to tube diameter, smooth radius mandrel bends and muffler design is essential for high performance. With 20 years of experience in exhaust system design, we have built a superb exhaust system for the 350Z.

Polished 304 Grade Stainless Steel twin 2.5 inch - in / twin 2.5 inch - out / True Twin Internal APS muffler. 304 Grade Stainless Steel is manufactured with higher nickel content than traditional 409 Grade as used in other systems. 304 Grade is not only more robust at high exhaust gas temperatures but also delivers a more durable finish.

By dissipating the hot exhaust gasses more efficiently, the APS High Output exhaust lowers the thermal load on vital engine components such as pistons, combustion chambers, valves etc., particularly at high horsepower levels.

The end result is an exhaust system that produces high outright power with stronger low to mid range torque. And in the case of the APS Twin Turbo System, improved turbo response (no lag) and maximum durability.

Further good news for the performance enthusiast is that the APS High Output Exhaust has provision for the stock wind deflector on the leading side of the muffler assembly. The stock wind deflector is an aerodynamic aid that slices through the turbulent under body air flow and channels air under the muffler.
