Hi All, I just had my lift redone because the mechanic who installed it the first time did it wrong, I took it to a shop in North Jersey and they did a great job of fixing the probelms.
I also installed a MagnaFlow exhaust and an AEM Bruteforce cold air intake trying to improve my mileage.
I have seen about 2Mpg improvment so far but I was talking to my nephew and he told me that the Jeep Liberty has 2 small catalytic converters that come off the manifolds and this is a 1.5" pipe which adds restriction to the exhaust resulting in less then optimum performance. Does anyone out there know any thing about this and is there any aftermarket subtitutes
Thanks.

Rusty`s Lift, all armor, BB`s, locked, and tons more stuff...and more to come

Just curious... what kind of gas mileage do you get? I get about 13mpg pretty consistently. I have 11,000 miles right now and a few people have told me that I will get better gas mileage when the engine is broke in more. Dunno if its true though.

Before the lift and tires I was @ 19-20 after the lift and tires I went down to 15-16 with the CAI and the Cat Back exhaust I"m @ 17-18.
I"m a little heavy on the petal but if I make a consceince effort and keep it light I can do 19-20 MPG.
My best was 22-23 on a trip to Canada. I have just turned 100,000 miles and I this is the best Jeep I have owned so far.

Your not the only one bud...I have a flowmaster 40 on my KJ with wider pipes and I have filled up once. I saw around 14.6 mpg with mixed driving. This tank should show the true colors of how the new muffler helps. I am looking into intake to see if that will help as well.
