I know what catback I'm gettin. I'm down on that GD on the Greddy SP. Now need to know which Y-pipe to get and which High Flow cat to get. I did a search and seen alot of people complaining about the cattman Y-pipe and how it didn't fit right and made the car shake and that cattman doesn't have good customer service. Which Y-pipe is better the Warpspeed or the cattman. Which gives better gains and a better sound or are they the same. Also I noticed you can get the warpspeed Y-pipe with a high flow carsound cat for about the price of just a y-pipe from cattman. Is that cat as good as the RT cat from custom
maxima. So basicly please let me know what the best setup is. Cattman and RT Cat, Warpspeed Y and RT CAT or Warpspeed Y with carsound cat. Please give opinoins, want to order as soon as possible.Also are the obx headers from midnight motorsports any good, because I always read around hear they don't do anything for the max.
