To
achieve optimum gas flow and minimal exhaust back pressure is essential
for high power. APS High Output Exhaust systems for the MY01 Impreza WRX
really perform.
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 (6.8 psi
back pressure and APS high output exhaust system (an outstanding 3.5
psi).
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.
Careful attention has been paid to exhaust
noise and note without compromising outright performance.
Full stainless steel construction ensures
maximum performance and durability. |
