whats the difference between open headers and not open headers? just sound performance or what does it basically come down to? thanks

@silverdiaz7 open headers means, there are only headers, or the exhaust manifolds, they are not connected to the rest of the exhaust system. Usually its loud as hell lol, and open headers is bad it can bend exhaust valves, and you lose horsepower and backpressure. When you have an exhaust system it creates backpressure and creates more horsepower, but there is a good and bad amount of backpressure.

@PinelochTundra Cool, yea cause i have a magna flow set up for my exhaust, and barely bought the jba headers but still havent had the chance to put them on, whats the difference between reg and y pipe? and do high flow cats make a big difference? yea im not that into loud ill rather go for performance so i will def. not get open headers for my install
