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

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 replacement muffler system.   

The end result is an exhaust system that produces high outright power with strong mid range torque. All this with improved turbo response (less lag) when running large turbochargers and maximum durability. 
 

Careful attention has been paid to exhaust noise and note without compromising outright performance. A strong but subdued exhaust note with no drone at highway cruise and well matched to the dynamics of the MY01. 

The chart below shows total exhaust back pressure at full throttle and compares the standard exhaust (9.6 psi back pressure) to the APS muffler high output replacement (an outstanding 6.8 psi back pressure).
