Bad Factory Cat?
Posted: March 24th, 2009, 11:11 pm
To make a long story long:
My cat was plugged badly, and from all indications, had been for a long time. I think it was partially plugged from the factory (Rubicon ordered in Dec. '02). Brand new, the power just died above about 4000 rpm, and I averaged 14.3 mpg, with the stock 31" MTR's.
Now I've got a 2" lift and 32" tires, and a stroker, and after rodding out the cat, I'm averaging 16.2 with my foot in the floor. The stroker is the animal I had always hoped, running strong past 4500.
Have any of y'all seen this with your own rig?
