Exhaust Question.
I have got a serious question. Does a 2 1/4" or 2 1/2" exhaust give you that much HP? Can you place a 2" one on and get the same? I have heard that some people place a 2 1/4" on and loose HP.
I know my 1.5L don't put out a lot HP to begin with. Has anybody did dynos for these size exhaust? My belief is that if a 2" will be enough to get you in the 200hp range. Is this true?

Exhaust size is directly related to engine size. On a 1.5L I would go with a 2", maybe a 2.25" tops. 2.5" would probably loose HP and torque, except at the extreme top end.
