OK, which ones are better?? HKS?? JUN??

equal lenght?? unequal lenght??

What are the pro`s and cons to fit them on a fairly modded STi6??

What do they sound like and what power gains should one expect??

Thanks in advance

 

I run Gruppe 'S' available from the US for 400$ inc. up-pipe. Do you have a mappable ECU? With a re-map I gained about 25 bhp over ported O/E cast headers. It will depend on your other mods.
