I agree...the shiny pipes look cool, but they are probably actually helping you due to the fact that you appear to be running a stock tune(until the intense arrives) with the 3.4. You will probably be starving for air if you are not already at this point. The plog will help out a lot with reducing your KR. Are you scanning somehow now? It is too bad they don't make the nice shiny tubing with a good filter and sell it as a kit in the 4"...That would be worth some cash. Good luck modding though.
