I took out the x pipe as I needed some room for the gearvendors install. So my exhaust goes straight into the racepro mufflers. The car runs great at the moment. Our last race was 11.46 at 118. Prior to that we were at 11.7-12 sec. Amateur drivers here so there is much to be improved on. Launch and strip manners are good.
I know the cam is not ideal for naturally aspirated without nitrous as it was designed for a bit of boost. This may happen but not this year as I do not want to put a rollcage in. I would like to have consistent 11.50 time.
SO.... Would the installation of cutouts provide a bit of an advantage to take the 11.8s times to be more in the 11.5 times? I would never run open cutouts on the street. Older video of my exhaust sounds.
