Re: Removing Baffels
open pipes work great in a drag racing application where you have a highly modified engine that needs to intake and exhaust as much fuel and air as possible in a brief period of time. But for the street in an EPA engine any benefit you could gain (and it's debateable whether there would be any) would be in an RPM range that normally you would never use. For anyone considering open piped also keep in mind that besides probably a performance loss in low and mid range RPM's that you can also damage your engine if not configured right. I beleive if I remember correctly (and I may be wrong) that you need a minimum of 22" pipe length or chance warping the valves at shutdown due to cold air rushing back in to the head up the pipe. At least with the old ironheads that was the rule couldn't swear to it with the new stuff.
