Thought of getting carpenter kit, but I am afraid once you do that things might break down more.
And I don't understand why you can't use jardine pipes and the Tunboy , how much power would you really notice or would you?
Just going to tune boy and K@N filters and Jardines I went from getting 42 miles per gallon to 33 miles per gallon with out pushing it. And I was told at the time you will most likely get more because it will breath better.
So doing this kit what do you really get 18 miles per gallon ?
