Hi,I have heard about a type of exhaust system you can install on your car where when you press a button or flip a switch, the headers or some part of the exhaust opens up basically making the car temporarily have open headers. im not sure what type of exhaust this is/what it is called. if anyone knows that would be greatly appreciated. thanks
Hi. The feature you are discussing is not an exhaust system - it's really just a part you add to your exhaust system. It is more less a gate valve. It is typically installed on a car with headers, right behind the collectors. In one position, it allows the exhaust to flow normally through the rest of the exhaust system (mufflers and tailpipe). In another position, activated by a switch you will install in your car, it will allow the exhaust to flow directly out the side of the car, emulating open headers (andvery loud!). Before this device was invented, some old school cars used a sort of mini Y-pipe behind the collector, with the end facing out the side of the car closed with a bolt on cover. Once at the track (or whenever you wanted to run open pipes), you would just unbolt the cover.
Hello If you are going to replace the Master Cylinder you might as well drain all the brake fluid and refill with new anyway. As it would need bleeding anyway Andy C
