test pipes

[dac55]

Does a test pipe increase or decrease gas mileage on a all motor car? I've heard it does and doesn't. I think it does since there is less back pressure. Just trying to squeeze more miles out of my car since I drive so much. Let me know what yall think.

your mileage may go down because it will have a little more power and you'll probably be enjoying said increase in power (even though it won't be substantial).
