hey all, i am thinkin of getting them until i read the other post about them, i wanted to run the 18" purple hornies straight off them with turn downs, will that work or will i have to have those S ext.?? i dont want to spend very much money, i dont have emissions, and loudness isnt a real factor, but open headers is too loud, maybe a Dynomax bullet muffler off the headers would work, let me know thanks
