  • Sideways exhaust?

    I heard this a long time ago but I forgot to ask. One of my friends is a big import guy and I asked him why he cocked his pipe to the side. He said that the sideways fartcan reduces drag. I'm not sure if I believe that or not. I just wonder if there is any truth about gaining anything front cockin it to the side. (not that I would do it)

    There is no gain from doing that. It makes no difference. He probably had no other explanation. If you think about it aerodynamically, a sideways pump would cause more wind resistance. Stick your arm out the window while you drive. Stick it straight out, then stick it out like you're pointing toward the side of the road. What puts more wind resistance on your arm? The cocked arm...

        My first thought was to laugh out loud. Very loudly.

        If anything cocking it sideways would increase the drag because it would increase the frontal area.

        But with it cocked sideways you would get a venturi effect. The air going by it would cause a suction out of the exhaust pipes. Look at a NASCAR car. They come out at a 45 to get the venturi effect. I really doubt it would help a 2 liter mountain dew powered civic much.

          i think they cock it sideways so their bumper doesnt get black with oil and who knows what else comes out of the muffler.....

            Man.... if turning one fart can sideways reduces drag, I guess my exhaust system with the two turndowns rotated to the center may be making my car almost "drag free".....



            Wait a minute... now I remember, I did that because it has a better chance of passing the noise tech check at the local track.

              Fred you didn't do your homework. One will give you reduced drag, two pointed towards the center will equalize and therefore no gains.

                  While we are having this discussion about possible gains with the exhaust I found one that's even better.



                  These tips bent upwards will give the car more downforce in the back resulting into better traction.

                  Do not install those on a single exhaust car since you may spin around due to better traction on one tire only!

                    If you turn it sideways will it help you do donuts?
