haha yea. i didnt take it off. by the time i wanted to do it i had just finished reinstalling the driveshaft and exhaust on my friends 535i, and i was hella tired (and it was raining)Mr.Ames said:i had to back my car into the garage with no exhaust manifold (with the hood open) cuz i had to take my header off to get it re-welded. it sounded disgusting and i threw a CEL right away

yea i was wondering about the backpressure issue, thats also why i was hesitant about it. i dont plan on doing it. hopefully someday ill have the money for a header and exhaustthejetman said:(lol) besides no back pressure is bad for your EXHAUST VALVES! your exhaust not only directs spent air and carbon away from a 200 degree motor. The piping is designed in such away that with minimal effort by the enigine, the spent gasses are almost "sucked" out due in part of the diameter of the tubing and the amount of pressurized gas leaving the motor.....(blah) don't do it man.....
