I found a Weapon R intake and header combo for sale for 350 dollars. I've been trying to do some research and from what I can find they seem to be pretty good at what they do. My question is that a far price for used items?

Decent price but if you dont get at least an additional 14 inch resonator installed in the midpipe you will CRY. The end

 

That's a good deal considering I sold my header for that alone.

 

18"resonator prevents that (at least it did for mine lol)
