well the top speed or the other ebay ones are all the same! too rough for me. the purpose of the manifold is to get you some more top end power and with the cheap manifolds i dont think too much can be accomplished! greddy one is 100% better made and looks alot better.$150 more for the greddy one i dont think its alot more to ask condisering that you dont have to polish it or bead blast it etc etc! may come out to almost the same after you get the cheap one treated!! .... for the $220 or cheaper i guess its not bad but then you might run into some problems in the long run! everyone gets different results!
