The
APS DR Series 3.5" Turbo to Tip Race
Exhaust is a true 3.5" internal diameter
exhaust system through each and every section.
By utilizing the latest technology precision
mandrel bends with the smallest possible bend
angles spread over the maximum possible length,
optimum exhaust gas flow minimum exhaust back
pressure is achieved.
By dissipating the hot exhaust gasses more
efficiently, the APS DR Series race exhaust
lowers the thermal load on vital engine components
such as pistons, combustion chambers, valves
etc., particularly at high horsepower levels.
Another significant benefit of the DR Series
race exhaust is better transfer of exhaust
gas energy to the turbocharger which results
in faster turbocharger spool-up and more efficient
turbocharger operation at high power levels.
A great deal of development effort has also
been put into accentuating the deep Subaru
boxer engine note - this exhaust is not for
the faint hearted and guaranteed to excite!
