Boost and Vacuum Actuated exhaust cutouts Here at Loudvalves we sell Boost actuated exhaust cutout valves and turbo accessories.
The boost activated series are fully opened at about 6psi. you can use a boost controller to open at higher boost pressures if desired
Common Question: Do they valves leak? they may have a slight exhaust leak at idle. the vacuum your car makes helps to "suck" the valve closed, nevertheless they may still have a slight exhaust leak, some customers say its not noticible, some say it is.
