I thought maybe the back pressure caused by lack of muffler can be bad for the engine, but hopefully a few days worth of driving won't cause any damage. > BTW - in my experience, car's without muffler are not loud for the > driver unless the throttle/air flow is closed, so as long as you keep > accelerating, it shouldn't be too loud :-) It's not bad at around 2500 rpm or higher on the highway, but below that it sure does turn heads! My only other minor concerns are asphixiation from the exhaust fumes and permanent hearing damage... -jw
