well i found out from legend nisan today my vibration is due to a bad engine pipe aka flex pipe, and the rest of exhaust. it is all stock. So now I guess i am now forced to have to get a greddy exhaust. I have one question for people, greedy is only a cat back system, where do i get a flex pipe coming off the headers and a new cat. what should i use? Also what do people think is it a waste or should i get something else. I heard 3a was good too. plus does anyone know if greddy contains a resonator thanks

 

give warpspeed performance a call. what you need is a Y pipe. (the part with the flex section on it is the y pipe). they're pretty cheap, relatively speaking.
