I have the banks headers now but have not fit them on my 08 JK, the reason is that we have installed JBA and Gibson headers and both of them have problems which are broken bolts on the headers or peices of headers flange braking off, burned ignition wires, melted valve covers, fuel air/mixture problems.

Any feedback will be cool

 

anybody has fitted them or has an experience 2 share

 

I have yet to figure out why people are relacing headers with headers. It just defies reason. I can almost promise you with no other mods, if you swap the factory "manifolds" for any shorty header available, you are not going to feel an improvement. The JK already has headers on it from the factory. They are a three tube into one collector design, just like any other available header. Until someone comes out with a full length header, there's no sense replacing the stock ones. Melted valve covers? Really now, were those "headers" worth all that?
