The lowest possible total exhaust back pressure after the turbocharger is vital, not only for turbocharger response and engine performance, but more importantly it lowers the thermal load on the engine - particularly at high power levels.

In addition to the huge 3.5" APS turbocharger down pipe - crafted from 304 Stainless Steel with internally divorced wastegate and 3.5" intermediate pipe, APS offers an optional high energy exhaust system to deliver true free flowing extraction of hot exhaust gasses.

Precision manufactured with durable highly polished 304 grade Stainless Steel and employing APS true dual exhaust - zero back pressure technology from the APS intercooled twin turbo, this exhaust system has the capacity to deliver huge horsepower and crisp turbocharger response.

From the 3.5" intermediate pipe included in the base APS intercooled single turbo system, exhaust gasses are split into two 2.5" pipes and into the true dual (internally divorced) APS muffler.
