You're not wrong there Vocky. I finally got a chance to swap out the panel filter and the car feels a lot livelier now. It was practically asthmatic before but it feels more responsive now and pulls from lower down the rev range. I wasn't able to mod the inside of the airbox but will be looking at that later on.
I was considering a cat-back stainless exhaust system so are there any companies that Griffin fans can recommend? A remap might be on the list as well.
