I'm trying to figure out the size of my gas tank and I think that it's around 12 gallons
. If someone's really bored, I'm getting about 220-230 miles to the tank, what's my gas mileage? I think that the straight pipes have helped considerably with my gas mileage.
do you have your owner's manual?.... cause that'll tell ya

There's backpressure, just not as much as there would be with mufflers. I have yet to see you say anything about the straight pipes hurting gas mileage. And why did I notice a gain in top end if it's really hurting my car? It's a unique set up, I'm sure that you haven't tried it.
