2009 Mitsubishi Eclipse GT - Power Pages

Notes
Almost any time OE catalysts are removed, a whole world of engine management problems opens up-anything from annoying check engine lights to ECU "safe modes" and all-out vehicle failure. Using the supplied O2 sensor adapters, we didn't experience any of these with the RIPP headers, but mid-range power and torque fluctuations from run to run were evidence of the ECU at work, trying to "correct" the increased power the headers brought. RIPP does offer a simple solution with their "BRAT" ECU plug-in, but we'll have to save that test for another day.

Conclusion
Outputting 290.5 whp and 284.1 lb-ft of torque, our Eclipse GT was transformed from a decently quick, aggressive-sounding commuter car into a tire-roasting, Z-killing, roaring beast, begging to be taken to the next level. We're not sure if any modification will continue to the car . . . but we're dying to drive a gutted one with sticky tires, a tuned suspension and a RIPP SDS supercharger!
