quick question
no cat= catalytic converter which is only good for emissions taking it out improves exhaust flow and frees up a little horsepower/torque. 3.55 gears is something i have a hard time explaining lol. the drive line rotates 3.55 times for the tires to spin 1 time. LS means limited slip or posi-trac (both back tires spin) mine just spins 1 wheel.
If you want speed, then go get a mustang, not a F-150. The speedometer only goes to 90 for a reason. These trucks aren't built for speed. I had my truck 75 one time and I thought I was gonna wreck. Lol. Of course, my speedometer is a little off because of the tires. It doesn't like the interstate either.
