just a question?
hey ive got a 90 civic si hb with a 2000 civic si motor and I recently put a header on it that did not line up at all so they had to do some customizing. anyway, right now im running a straight pipe with resinator and I need to know if a high flow or getting a regular cat would take away the raspyness with out a loss of power.thanx
