| Outstanding results right
across the RPM range to keep you grinning from idle to red line!
Significantly enhanced mid range torque and power (at 3,300 RPM an increase from 40 kW at the wheels to an outstanding 105 kW) really transforms the STI into a torque monster with fantastic straight line acceleration. An added benefit is an outstanding improvement in throttle response and low RPM torque. Anywhere, anytime, the Sprint Spec enhanced STI is swelling with turbo boosted torque.

"On the road, it all means the APS STi is a more relaxing drive because you're not constantly hunting back through the six-speed for a ratio that's actually gonna spool up some herbs. The thing will actually accelerate in sixth now, which is really saying something."

At higher engine RPM, the improvement is just as dramatic. At 7,500 RPM power output is increased from a standard power level of 121 kW at the wheels to a wicked 152 kW! - That's 35 more kW at the wheels!

The APS High Output Exhaust system
for the STI for example has set the benchmark for performance exhausts.
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 STI. |

The perfect exhaust for daily
driving and truly exhilarating under high speed driving conditions.
All components supplied have
been carefully matched and exceed APS's strict performance and reliability
criteria. With many kilometers of road and track testing, on APS engineering
vehicles ensures maximum performance and component durability.

have competed and won many hill climbs, club sprints and road rallies.
At APS we have a simple philosophy when it comes to performance. To
come first, first you must finish.
Performance is not only measured
