APS delivers what is arguably the ultimate in high performance exhaust systems for turbocharged applications.

Huge exhaust gas flow and low backpressure are critical for delivering high horsepower, crisp turbocharger response and great gas mileage - The APS high output stainless steel exhaust system excels on all counts.

Twin 3" tubing Crafted in premium 304 stainless steel and precision TIG welded, the APS exhaust 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 Corvette.

By dissipating the hot exhaust gasses more efficiently, the APS High Output exhaust also 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 horsepower with far stronger low to mid range torque (greater power and torque under the curve). And best of all, improved turbo response (Zero lag) and maximum durability.

Careful attention has been paid to exhaust noise and note without compromising outright performance. A strong but subdued exhaust note that leaves no doubt there is a big cube Twin Turbocharged V8 under the hood - yet very refined with no drone at highway cruise and well matched to the dynamics of the Corvette.

The APS High Output Exhaust System mates perfectly to the stock cat exit position and is the ideal upgrade to any high horsepower forced induction system (Twin Turbocharged or Supercharged) on the C6 Corvette.

Extreme flow turbocharger specific metal matrix (150 CPI) catalytic convertors and a 4-bolt flanged balance tube is included with the APS High Output Exhaust System.

For total peace of mind and bullet-proof, leak free operation, the APS High Output Exhaust System utilizes 4 bolt stainless steel race flanges throughout.

The APS High Output system is engineered as a complete system including every nut, bolt and gasket required for installation.
