Roger I have a set fitted to my 02 wrx fit was good havent had any problems upto date with them as for gains I wouln't know until the middle of march when it goes on the rollers mind you I had the car remapped by andy f as well as a few other bits added.For the price that you pay for them I dont think you can go wrong for unequal lenght headers + you get the flexi uppipe as well.

 

oops my mistake roger I thought you were on about the manifolds.
