With all of the discussions going on about which exhaust/high flow cats has the best sound, I am interested in what (if any) increase or decrease in the miles per gallon has been noticed. I am going to pull the plug next week on a Invidia Gemini CBE, CNT HFCs and K&N filters. Although I am more interested in the new found sound and performance of the new exhaust system, I am curious if the MPG is affected? I would guess that the MPG would increase slightly (if you can keep your foot out of it).
