Are there ANY downsides to having an open dump pipe?!? I just put one in a test pipe that took the place of my cat...I want to run an open dump, but I also don't want to hurt my car!!!
Dad, like any other dad, said that the car would need SOME back pressure, but I explained to him that on a turbo car...the turbo IS the back pressure, and that as long as you used a downpipe, anything after it was just restricting the car...WAS I CORRECT IN SAYING THIS?!? I don't want to harm my car in anyway, but DAMN...does it sound COOL
Thanks - John
