At $250 these really aren't cheap. Cheaper than Stillen or Powertrix but not the $90 Ebay variety. I found them on CZP not on Ebay. I know damn good and well not to get shit ass Ebay parts. Is CPZ not reputable? Since I do not know the full story I come here. I use the search to find 95% of my questions so I do not annoy edgey "experts" like you. Is it really necessary to reply like I am a F'n moron? It is a simple question with a simple "no good" answer.
