OK here goes20 inch wheel and tire 31 inches tall and 3.42 gears, Ive lost alittle low end horepower. Im running a short glasspack and 2.5 inch daul outback.I have a 50 series flow thats just sittin around and Im thinking this might help my low end with a little more backpressure.I know gears would be the perfect fix..4.11
I just dont have the funds
Any opinions or Ideas or better yet where to get gears or a rearend 200.00

4.10s will definitely help but kill your gas mileage. A stock muffler will help your torque since you'll need the backpressure.

I have 3.73 gears and a buddy of mine has the same truck with 3.42 and I can run off and leave him. But any tire bigger than 31 in I would recomend 4.10. I recommend the flowmaster I love mine.
