All engines need some backpressure to make max horsepower. < Message edited by RTexasF -- 2/19/2005 7:38:06 AM > (in reply to Deleted User) Post #: 3

I disagree. I have witnessed dyno runs with and without open exhaust. In one case the engine made more HP WITH some restriction/backpressure. Not true in all cases I admit, but to call it a myth is not correct. < Message edited by RTexasF -- 3/23/2005 8:02:38 AM > (in reply to 2000Ex) Post #: 6
