this is my special title
If I was thinking of taking my 95 5.2liter Dodge Dakota to a dual exhaust system... how much would it cost and what benefits would I gain?
Kruz said:yes you would get a small to moderate gain in HP...
but ! the problem comes from the emissions side of this.
the EGR (exhaust gas resurculation) Valve is controlled by exhaust "backpressure". if you change the backpressure by creating a free flowing exhaust, you can prevent the egr valve from working , and then failing the emissions test for high N0X readings
