Hey y'all I'm getting straight pipes put in sometime next month. I'm getting them from the cat back 2, 2 1/2 in pipes with no mufflers. Will this effect my gas mileage, torque, or horsepower enough for me to notice?

Might effect your low end torque some but your mpg's will go down some, since you'll be stopping the gas pedal all the time, listening to them sound off! :D

Just do it... I doubt you'll notice any difference other then sound.

Yes you will have a little less low end torque but you really won't notice that its gone.
