Ronnie I would be ready for a retest to be honest as the tester at Gillingham said nobody with a kit car ever passes first time, even if you make adjustments on the day that is still not considered as first time pass apparently.
hi vern the intake system is bike carbs they do have filters but they are minimal at best.
i will be playing about with different exit angles and different methods of noise suppression. I tried a bike can on the exhaust just to see if it made a difference and with the bike re-stricter that is built into the can it made the volume so low that the engine was much louder than the exhaust. once i have the db meter i will carry out some tests before and after to see how much i can actually get it down by without over restricting the flow.
